2015/07/11 (S) Impactful Tools

Leave a reply

We had a small crowd for our SLAARC breakfast this morning but good conversation.  After breakfast we drove to Chuck’s house and picked up the manual impact screwdriver.  Barb was up in the thumb visiting her brother-in-law who recently lost his wife (Barb’s sister).  We lingered for a while and then left for home, stopping for gas on the way.

Back at the house I started a load of laundry and then went to work on the stop block screws.  Linda helped steady the ladder and pass tools and parts back and forth.  I got three of the four screws out of the two stop blocks but the head stripped on the forth one so I was only able to remove the aft stop block.  I tried different bits and even tried drilling a small hole in the center of the head to allow the bits to go in farther but it did not work.  The next approach will be a screw extractor, but first I have to go buy one.

We had soy yogurt for lunch with red grapes and I had a few pretzels with roasted red pepper hummus.  I kept trying to get to the basement to work on the desk design but kept getting detoured.  Once I finally reached my office I found that the mouse trap that I had placed under one of my desks was out in front of it.  The food was gone but there was no mouse, only mouse poop.  I realized that the trap was upside down which allowed the door to swing open.  Our best guess is that a mouse was trapped and the cats pulled the trap out from under the desk and accidentally turned it over while pawing at it trying to get the mouse.  Since there was no sign of a mouse having been caught by one of the cats my best guess is that it escaped, for now.

I checked e-mails and found the one with the credentials and instructions for the QTH.com web-hosting of SLAARC.com so I shared those with the other members of the SLAARC website team and then logged in to check out the log file I had created the other day as a test.

I decided to reconnect the Yaesu FTM-400 radio to the Diamond X-50 antenna on the tower so I could monitor the Novi and South Lyon repeaters while I worked in my office.  I had quite a mess on the ham shack desks and decided the best way to deal with it was to install Mike’s Icom IC-2820H in my car in place of our Icom V-8000 2m rig.  At least that would get the 2820 off the desk.  I checked that the mounting brackets and they were identical so I removed the V-8000 but left the mounting bracket installed in the car.

Mike had modified the power cord on his radio by cutting off the T-connector and replacing it with Andersen PowerPoles so I had to modify the power cable in my car to match as I could not modify Mike’s radio.  I removed the fuse from the positive (+12VDC) lead and then cut off the T-connector, leaving about 6″ of wire so I can add PowerPoles and make it into an adapter cable.  I brought my Hakko soldering station up from the basement, set it up on the floor behind the center console, ran an extension cord from the garage, and used it to solder PowerPole contacts to the two wires.  I then inserted them into the black/red housing pair and snapped them in place.

I mounted the IC-2820H, connected the power cable and connected the coax from the antenna.  I reinstalled the fuse in the positive lead, started the engine, and turned the radio on.  A couple of hams were chatting on the Novi repeater, one of whom I knew (Jim, KB8TAV).  When they finished I gave Jim a call and he came back to me, the first time I have been able to use the Novi 440 repeater from my car.  Jim signed off and I switched to the South Lyon 2m repeater and gave a general call.  Steve (N8AR) came back to me and we had a short QSO that verified the radio/antenna was also working on 2m.  As we were wrapping up Linda started fixing dinner.

Linda fixed a simple salad and Dr. Praeger’s vegan hamburgers with Daiya non-dairy cheese.  These patties were also squishy rather than firm and, like the ones at Zingerman’s Roadhouse the other night, where not very satisfying.  They tasted OK, and we ate them because we are not inclined to waste food, but there is a lot more to what makes food satisfying than just taste.  Sight, smell, and texture (mouth feel) are also important.

Linda had several TXT messages from Mara letting us know that she would be arriving tomorrow sometime before 2 PM as she wanted to watch the Wimbledon finals at that time.  Linda and I considered how best to accommodate Mara’s motorhome and finally decided to just pull our bus straight forward until the nose was at the edge of the concrete driveway.  That created more than enough space on the level part of the pull-through driveway for her to park and plug in to our 50 amp service.  The only loads we have in the bus at the moment are battery chargers so we used our 15 amp cord to plug it into a garage outlet.  Since I had to start it to move I switched it to high idle once I had it positioned, leveled it, turned on the OTR air-conditioning to put a load on the engine, and let it run for 30 minutes.

I returned to my office after dinner and work on the desk design for a while but by this point I was tired and not really in the mood.  The last time I updated the BCM page on our website was after the February 2015 issue came out.  I have had articles in the March, April, and May issues and will have articles in the June and July issues.  I captured the covers from March, April, and May and updated the page.

I exchanged e-mails with several people and spent some time looking at dual and triple monitor stands on EBay.  We rarely use EBay and the site made me change our password before it would let me log in.  There was a large selection of products but none of them were exactly what I am looking for.  There wasn’t any rush so I decided to revisit this tomorrow.

 

2015/07/07 (T) Field Day Photos

Leave a reply

We did not sleep well last night, were slow to get up this morning, and slower to get going.  A cold front was pushing in from the northwest with the promise of cooler temperatures and sunny, blue skies, but first we were in for a day of overcast conditions and rain, which started around 8:30 AM.  It was a perfect morning to sit quietly in the living room, reading, writing, and drinking our coffee but too warm to turn on the gas fireplace logs.

Yesterday Linda started researching RV parks in southern Florida for this coming winter and we spent some time this morning looking at them online.  There was one in particular, Riverside RV Resort and Campground, which caught our attention.  Located on the Peace River near Port Charlotte and Punta Gorda, it is a short distance southwest of Arcadia where the annual Buss’in rally is held.  We went to the rally two years ago and had a great time so we will go again this year if we decide to winter in Florida, which is our current inclination.

One of the reasons for us to winter in Florida, at least occasionally, is our many contacts there.  Our friends, Steve and Karen, bought a mobile home near Venice; our friends, Chuck and Barbara, bought a lot at Pelican Lake in Naples; our ham radio friends, Bruce and Linda, bought a house on 25 acres near Brooksville; our GLCC fiends, Ed and Janet, bought a place that I think is near Sarasota; our FMCA Freethinker friends, John and Marian, bought a place in Dunnellon; and our other FMCA Freethinker friends, Ed and Betty, bought a place in Bradenton.  In addition to all of those folks quite a few of our RV friends, like Pat and Vicki, spend the winter in Florida, and the state has a lot of things to see and do, including one of the best state park systems in the nation.

Linda left for her appointment with the dermatologist and I got to work at my desk.  I continued to deal with e-mails related to the SLAARC domain transfer and an ongoing conversation with BCM publisher Gary Hatt.  I got a Dropbox link to some Field Day photos from Steve (N8AR) a few days ago and downloaded them.  Last night I got a similar e-mail from Mike (KE8AGY) with a Google Drive link and today I got one from Jim (N8HAM) so I downloaded all of those photos.  I spent most of the rest of the day selecting and processing the photos I took and then processed all of the ones I got from other people.

I took a break to chat with Linda when she got back from her appointment.  I then removed the defective Morgan M-302N VHF/UHF Lightning Arrestor from the cable entry box and boxed it up to ship back to Morgan.  I took another short break for dinner, which was an excellent Farro and kale dish, and then worked until 8:30 PM when we had agreed to watch a movie.  This evening’s choice was The Imitation Game, a film about Alan Touring and the concepts he invented that allowed the British to build a machine that broke the coded messages generated by the German Enigma machine during WWII.  I spent another hour at my desk after the movie before going to bed and finishing this post.  Tomorrow morning I plan to finally upload some blog posts and then get back to work on the design of the custom desk for the bus.

 

2015/07/06 (M) Arrested

Leave a reply

Our morning started with coffee, once we got up, and then granola for breakfast.  We are both in better health, generally, than we were in our 30s, 40s, and early 50s, but having Madeline here requires a different kind of constant energy and attention and we are somewhat tired by the time her parents take her home.  It’s a good tired, of course, but we were still tired this morning and slept in for a while.

I had hoped to get back to work on the bus today but the afternoon highs were forecast for the mid-80’s which would make for less than comfortable working conditions.  The forecast for the rest of the week was for highs in the 70’s so I decided to wait another day.  I really needed to get back to work on the bus but I also had other things to take care of that seemed at least as pressing.

At the top of my list was the SLAARC website.  Scott Neader had successfully copied the SLAARC WordPress website from GoDaddy.com to QTH.com and changed the domain pointers to point to the QTH servers.  He needed me to check that everything was working correctly.  He was also preparing to transfer the domain name registration and needed my involvement for that process.

Continuing with the ham radio theme, I needed to resolve how I was going to mount the new Diamond X-300NA 2m/70cm antenna and possibly remount the outside omnidirectional antenna for the cellular booster system.  That meant doing some minor engineering and possibly ordering parts.  I was also preoccupied with the fact that I was unable to participate in the SLAARC info net last night, apparently due to some malfunction in our ham radio system, and it was going to bug me until I figured it out.

Last, but not least, was the fact that I was now one month behind on uploading posts to our blog.  The farther behind I get the more of a chore it is to get caught up.  Like cleaning up my e-mail inboxes, which I also need to do, it finally becomes “the” thing I “have” to take care of before I can concentrate on any other work.  I hate it when that happens, but it is a recurring problem and I have no one to blame except myself.

I often seem to spend the first part of each morning finishing up my blog post (draft) for the previous day and outlining the one for the current day or making notes for future days.  It’s my way of reflecting on what I have done and thinking ahead to what I need/want to do next.  By the time I actually got to work this morning it was after 10 AM and Keith showed up to cut the grass.  It did not rain this past week and he was finally able to cut the grass at the west end of the property, which is low and often wet.

Before going to my office I checked the rebate paperwork which Linda had assembled for the new Yaesu ham radio and got it ready to mail.  I also started filling out the prescription form to send in to Catamaran Home Delivery when I realized the doctor had written the Rx for 30 days instead of 90.  I called the clinic and they said it would (probably) be OK to have Linda bring it to her appointment tomorrow and have the doctor rewrite it.

When I finally got to my office I looked at the SLAARC WordPress website on my computer to make sure everything was working.  The only thing that was not working was an online tool for logging check-ins for the Sunday evening info net.  I e-mailed Scott about that and then logged in as an administrator and updated several plugins.  I logged in to the FMCA-GLCC website and updated it and then did the same for our personal website.  I then created a support ticket at iPower.com regarding the broken FMCA Freethinkers website.  I dealt with SLAARC related e-mails throughout the day.

I spent the rest of the morning editing blog posts for the second half of June and early July and then started selecting and processing photos to use with blog posts, and processed those further.  By the time I quit working I had photos ready for everything except the three days of the ARRL Field Day event.

It was a nice day, if a bit warm, and we had the house opened up including the basement doorwall.  Other than a short break for lunch by 2 PM I had sat long enough and decided to setup the new Diamond X-300 2m/70cm antenna on a temporary pole.  I rummaged around the garage and found the four section pole I had used at the old house.  The pieces were buried under a pile of GLCC related PVC flag pole sections but I was able to slide them out.  I cleaned up the swaged connections and used a light coating of anti-seize compound before assembling them.  I stood it upright on the ground at the NE corner of the deck and zip tied it to the corner post at three points.  I then set up the 7-foot step ladder on the deck and removed the upper two sections.

I unbolted the X-300 antenna from its storage place on the side of the 40-foot tower and set the base on the east deck railing.  I then got one of the 35-foot heliac coax cables from the basement and attached it to the feed point of the antenna.  With Linda’s assistance I mounted the antenna to the top of the topmost mast section and zip tied the coax to the mast.  Back up on the ladder I was able to slip the upper mast sections into the lower mast sections and add a couple more zip ties to secure the coax.

I routed the coax over to the cable entry box (CEB) so that it was not visible.  The antenna is shielded from view by our Norway Crimson King Maple tree and the mast is very inconspicuous; not bad for a temporary installation.  I disconnected the X-50 antenna coax from the Morgan UHF/VHF Lightning Arrestor in the CEB and attached the coax from the X-300 in its place.  I went back to the ham shack, turned on the Yaesu radio, and listened.  Nothing.  I tried calling the South Lyon 2m repeater but nothing came back.  I tied the Novi 440 MHz repeater…nothing.  I turned the radio off and moved the coax to our Icom IC-7000 radio and repeated the tests.  Same results.  Something was clearly wrong so I called Mike (W8XH) to see if he could help me figure it out.

Mike was out but on his way back home and called me when he was back at his base station.  We verified the transmit and receive squelch settings on my radios and then tested both antennas on both radios.  Using our cell phones we confirmed that he was not hearing my transmissions and I was not hearing his, either direct (simplex) or through the repeaters.  It was now clear that RF signals were not making it into or out of my system and there was one component that was common to all configurations; the Morgan M-302N VHF/UHF Lightning Arrestor.

I have a coaxial cable adapter kit that allows me to temporarily interconnect most of the connectors used in amateur radio coaxial cables.  At Mike’s suggestion I used the kit to assemble an adapter (barrel connector) with N-female connections on both ends.  I then disconnected the antenna and radio coaxial cables from the lightning arrestor and connected the radio coax directly to the X-300 antenna coax.  Back in the ham shack I tested this configuration with both radios on both repeaters.  I was receiving both repeaters with S7 to S9 signal strength, which is good, and very little noise, which is also good.  Mike reported that my signal was very strong into both repeaters and that he was receiving me full-quieting.  I shut the radios off and then switched the connection in the cable entry box to the X-50 antenna.  We repeated the tests with the same results, confirming that the problem as the lightning arrestor and only the lightning arrestor.

Although I was disappointed that the M-302N was defective I was overjoyed, or at least relieved, that everything else was working perfectly.  Although the new X-300 antenna turned out not to be “necessary” having it on a mast above the tower will give us an even better transmit and receive capability than the current X-50 installation.  I even have some hope of being able to reach repeaters farther away in the Detroit metro area as well as in the Lansing, Flint, Ann Arbor, and Ypsilanti areas, and perhaps much farther beyond.  Windsor (Canada) and Kalamazoo are possible when atmospheric conditions are right for longer range propagation, and the Saginaw, Mt. Pleasant, Fort Wayne (Indiana), and even Cleveland (Ohio) areas are not out of the question.  Once, at the old house, I was on the Spirit of 76 repeater atop the Renaissance Center in Detroit when it picked up a 2m station from Iowa.

Relieved of my concerns, especially about the operation of our new radio, I returned to my computer-based tasks.  The first thing I did was e-mail Chris Perri at KF7P Metalwerks regarding the lightning arrestor, which I purchased from him as part of the cable entry box.  He apparently forwarded my e-mail to Morgan Manufacturing Inc., or at least e-mailed them, as I got an e-mail from Bob at Morgan with instructions on where to return the unit.  It has a lifetime warranty and he indicated they would repair or replace it as needed.

I spent the rest of the afternoon and evening, except for dinner, working on photos.  Dinner was chickpea salad on a bed of greens with steamed baby bok choy dressed in rice vinegar.  It was a perfect meal for a warm summer evening.

The humidity had been up all day and rose as the temperatures dropped at sunset, although they did not drop much.  Linda was watching an episode of Scorpion when I finally came upstairs.  We watched an episode of NCIS Los Angeles after that and then an episode of Two and a Half Men, which I have always enjoyed.  We turned on a small fan but it was a warm, uncomfortable evening for sleeping.  For whatever reason we did not turn on the air-conditioner although in hindsight we should have.

The day started with Grandma Linda’s fabulous, made from scratch, blueberry vegan pancakes for breakfast, which Madeline helped make!  After breakfast we took Madeline to the Howell Farmers Market (HFM).  She had been to this market with us once before and it was a beautiful Michigan summer morning for a return visit.  On the drive over we discussed why it is that you cannot buy a farmer at a farmers market and you cannot buy a garage at a garage sale.  English can be a funny/strange language.

We walked the entire market, which is not really that big, and Linda bought some fresh strawberries.  A couple of the regular vendors were missing.  In particular we wanted to buy some more soap from Marjorie but she was not there.  Madeline enjoyed checking out the child and doll sized wooden furniture that one vendor had for sale.  We kept an eye out for someone selling jelly beans but did not see any so we stopped at the CVS on the way home and got a small bag of them.

We had just gotten home and I was unlocking the front door when Brendan and Shawna arrived.  We had a nice visit and they stayed for a light lunch.  By the end of lunch Madeline was showing signs of being ready for her nap so Brendan transferred the car seat and stroller from Linda’s car to their car, gathered up all of Madeline’s things, and loaded their car.  Madeline left with her parents at 12:30 PM and Linda laid down for a nap shortly thereafter.

I looked at the SLAARC WordPress website on my iPad to make sure it was working.  I checked most of the pages except for the Member Only Area, which requires a login, and they appeared to be OK.  I then went to my office to deal with things that needed to be dealt with from there.

My first task was to update the roster and financial records for our FMCA Freethinkers Associate Chapter.  I sent e-mails to new members, uploaded the updated roster to our Dropbox, and e-mailed everyone that they were available.  I had received the draft copy of the June 2015 issue of Bus Conversion Magazine on Friday.  I proofread part 3 of my 4-part article on the exterior renovation of our motorcoach and sent corrections to the editor.  I then settled in to edit blog posts.

I took a break for dinner.  Linda cooked Brussels sprouts and heated some vegan riblets.  The barbecue sauce on these riblets is very tasty.  We had vegan chocolate cupcakes for dessert and they were very tasty too.  I then went back to my office and continued editing blog posts.

I took a break just before 8 PM to join the South Lyon 2m Information Net using our new Yaesu FTM-400DR/DE RADIO but I did not hear anything except noise.  I left the radio on for a while and then turned it off.  I switched the coax to the Icom IC-7000 and turned it on but did not hear anything there either.  I turned the IC-7000 off, switched the coax back to the FTM-400, turned it back on, and went back to work at my desk.  Around 8:30 PM the squelch started opening and I heard very faint voices way down in the noise.  After listening carefully I was able to determine that it was Steve (N8AR) running the net but I could not understand most of what was being said.

It was the first time in a long time that I had tried to participate in the net and I was disappointed that the new installation of the antenna on the tower and coax cables to the radios in the basement was not working adequately.  They were working OK when I tested them with Mike (W8XH) so it could have been an unusual band condition but Steve was obviously getting in from farther to the west than our QTH.  I enjoy operating and am looking forward to finally having our larger tower up and some HF antennas in operation but for now I need to concentrate on getting the VHF/UHF stuff working reliably (correctly and consistently).

I exchanged some e-mails with Gary at BCM regarding the magazine and then continued editing blog posts.  I got through the end of June by 11 PM and quit for the night.

2015/07/03 (F) 4th Anniversary

Leave a reply

Several SLAARC members were gathering at 10:30 AM this morning to unload the Field Day equipment from Steve’s trailer and store it in the South Lyon water tower.  I was going to join them but decided last night to stay home and work on the design for the desk and HVAC chase covers for our motorcoach.  Having played ham radio for much of the last week and a half I needed to refocus my time and attention on the interior remodeling of our bus.  Besides, Brendan was bringing Madeline to our house sometime mid-to-late morning and I wanted to be home when they arrived.  Today was Brendan and Shawna’s 4th wedding anniversary and they asked Linda if we would take care of Madeline for a couple of nights so they could have some time together without the constant demands of child care.  Of course Linda said ‘yes.’

I had a call last night from XPO Delivery Services letting me know the new refrigerator for the bus would be delivered to Chuck Spera’s shop in Novi today between 6 and 8 PM.  That meant I would have to be at the shop by 5 PM just in case they arrived early and could be there past 8 PM if they arrived late.  At 7:45 AM this morning I got a call from the Lowe’s in Howell asking if XPO could deliver the refrigerator in about an hour.  Sure, why not; I was still in bed but about to get up anyway and having the refrigerator delivered early would actually open up my entire day.  I hurried the process along, had Linda get the receipt, grabbed my iPad, and headed for Chuck’s shop in Novi.  Linda was getting ready to go for a walk as I left.

One never knows what the traffic will be like on I-96 headed into the Detroit metro area from the northwest but on this Friday, at the start of a major holiday weekend, the traffic was very light and I was able to get to Novi in the minimum legal time.  Traffic headed westbound actually appeared to be heavier than the inbound traffic.  I stopped at the Tim Horton’s on Beck Road just north of Grand River Avenue and got coffee which I had not taken the time to make at home before I left.

I texted Chuck to let him know that the refrigerator was being delivered this morning.  He called me back to clarify where to have them set it.  This would be a great weekend to do the swap as all of the other businesses around his shop building will be closed for the holiday, making it easy to get our bus in and out.  But his daughter arrived last night from New York and will be visiting for a week so the refrigerator replacement will have to wait, probably until at least next weekend.

By 9:30 AM XPO had not arrived so I called Lowe’s in Howell and talked to Erica in scheduling.  She said she would call the driver and see what was going on.  I texted a status update to Linda and continued to wait.  By 10 AM there was still no truck and no call back from Erica.  At 10:20 I was dialing Lowe’s again when an Enterprise rental truck drove past the building headed east and a few minutes later went by headed west and pulled into a parking lot.  Moments later my phone rang.  It was the XPO truck driver.  I explained where the driveway was and flagged them in.  When I ordered the fridge I gave detailed special instructions on how to find the building but the driver did not bother reading them and did not bother calling me until he had failed to find the delivery location for the second time.

They backed the truck into the area in front of Chuck’s garage door, lowered the refrigerator down on their lift gate, slid a pair of lift straps under it, picked it up, and carried it into the shop.  I looked it over as best I could and then signed for it.  Only later did I notice a small dent towards the bottom of the door.  I had an automated call later asking if I was satisfied with the delivery and indicated ‘no’, noting the arrival delay and the small ding.  The message said I would hear back from someone within an hour but no one ever called.  We do not plan to make an issue of the ding as we will be lucky to get it into the bus and into its alcove with no further damage.  Still, it should have arrived in perfect condition and did not.

I called Linda to let her know the refrigerator had arrived and that I was getting ready to head home.  She said Brendan had just arrived with Madeline.  As I started to back out of my parking spot Chuck arrived so I spent about 30 minutes talking with him about the timing and approach of the refrigerator swap.  I will almost certainly take our bus to his garage on a weekend.  Only later did I find out that Brendan will not be available to help for the next two or three weekends.  Ugh.  Chuck called a friend (golf buddy) who has narrow pallets (24″) to see if he could get a 5’ long section.  With the long forks set close together on his forklift we can slide the pallet over the forks and have a much more secure platform form for raising and lowering refrigerators, probably laying on their backs.

Linda called back and asked me to stop on the way home for some toddler toothpaste and a toddler toothbrush.  I did not know they made such things but I found them at the CVS in Brighton.  Not long after I got home Linda had lunch on the table.  She heated some veggie nuggets and set them out along with baby carrots, grapes, pretzels, hummus, vegan deli slices, bread, lettuce, and onion.  We all had a good lunch with lots of variety.  Brendan got Madeline down for her nap at 1 PM and hung around long enough to make sure she was asleep.  I took a few minutes to show him the new Yaesu radio before he headed back to Ann Arbor.

I was very tired and took a nap on the living room sofa which is especially comfortable for this purpose, better actually than for sitting on.  Madeline slept until almost 4 PM.  When she woke up she wanted her mommy and daddy and was a little weepy but Grandma Linda got her quickly engaged in doing things.  Linda took her for a walk to see the chickens while I went downstairs to check e-mails.  I responded to ones having to do with the transfer of the SLAARC website and domain name registration from GoDaddy.com to QTH.com and made mental note of others.  When they got back from their walk Linda brought Madeline downstairs to see Grandpa Bruce at work in his office and ham radio shack.  We told her we would help her become an amateur radio operator when she was older.

Linda decided that baking a vegan chocolate cake would be an excellent activity to do with Madeline and give us a nice treat for later.  Madeline helped pour and stir ingredients.  She ended up with chocolate cake batter on her face and clothes but it was worth it as she got to lick one of the spoons.  (Without any animal products, especially raw eggs, vegan cake batter is perfectly safe to eat.)  Linda had previously found a small baking set for Madeline that included a small bunt cake pan.  Some of the batter went in there to make a little cake just for Madeline and the rest was used to make 11 cupcakes.

After the cupcakes were cooked and taken out of the oven to cool Linda made dinner.  We had mock chicken strips (vegan), fresh sautéed green beans, vegan refried beans, and fresh berries leftover from earlier.  When the cakes were cool enough Linda got out the powdered sugar and sifter and we dusted them.  Madeline enjoyed the decorating but somehow ended up with powdered sugar in her hair, on her dress, and all over her face.  I took pictures and then Linda cleaned her up while I cleaned the floor.

After dinner and dessert we played and read a bit.  Linda had gotten three Sesame Street Workshop DVDs from the Howell Public Library so we all climbed up into the bed in our bedroom and watched one of them.  We played along with the various activities and games and encouraged Madeline to do the same.  The program ended at 8 PM which is Madeline’s bedtime.  Linda helped her in the bathroom, got her into her pajamas, and helped her brush her teeth.  She laid down without a fuss and drifted off to sleep. We stayed up until the last chime of the grandfather clock at 9:45 PM and then turned in for the night.  We are always satisfyingly tired after a full day of Madeline.

We were tired and did not get up until almost 8 AM.  Linda prepared a tofu scramble for breakfast, as we were almost out of her homemade granola, and served it with some cinnamon raisin toast and fresh grapefruit.  It’s the closest thing we eat to scrambled eggs and she serves it as an occasional change of pace from our standard granola breakfast.

I had my annual appointment with my dermatologist this morning at 11 AM.  I needed to pick up a cable from Scott (AC8IL) at Adams Electronics, which was on my way to the Henry Ford Health System (HFHS) clinic, so I left the house a little after 9:30 AM.  The drive was fine initially and I had a nice QSO (chat) with Steve (N8AR) on the South Lyon 2m repeater.  As I was approaching Wixom Road, however, all lanes of eastbound I-96 were stopped.  I was able to exit at Wixom Road and headed north a short distance to West Road which I took east over to Beck Road where Scotty’s business is located a little north of West Road.  I had a brief chat with Scott about the antennas on my tower before I left.

Two miles north of Scott’s shop I turned east on Maple Road (15 Mile Road).  The HFHS has many clinics around the greater Metro Detroit area and my dermatologist is located at the intersection of Maple and Farmington Roads in West Bloomfield.  That should have been an easy trip but there was construction on Maple Road that had the road down to one lane with flaggers.  There were signs advising motorists to seek other routes but I did not heed the warning.  I patiently worked my way through and arrived for my appointment about seven minutes ahead of time.  Good thing I left as early as I did.

My exam was fairly routine and Dr. Nydorf wrote out a prescription for Doxycycline.  I will try taking it (again) three times a week and see if it helps.  I headed straight for home after my appointment but took a different route.  Once I was back at the house Linda went for a walk.  While she was walking I removed the license plate from her car, took the protective (anti-theft) cover off, and cleaned everything.  When it was dry I put the new registration sticker in the corner, reassembled the cover, and installed the plate back onto the car.  I then started working with the various pieces of the new Yaesu FTM-400DR/DE mobile radio.  When she got back from her walk she heated up a couple of tofu hotdogs for lunch.  These are such simple fare but so tasty (with mustard, onions, and relish) and so appropriate for a summertime lunch.  They are also a really easy lunch to get on the table.

After lunch Linda took her car to the Howell library to get some books and children’s DVDs and then stop at the Meijer’s supermarket to pick up a few grocery items for Madeline’s visit this weekend.  While she was running errands I assembled our new Diamond X-300NA antenna.  Once it was assembled it was over 10 feet long so I stored it by mounting it to the side of the tower.  I put it up as high as I could reach from the ground to get the three counterpoise (elevated ground plane) rods above eye level.  Moving it to the top of the tower as a replacement for the Diamond X-50NA will have to wait until next week or later.  The exact timing will depend on the weather, Mike’s (W8XH) availability, and whether I have acquired appropriate standoffs by then for the X-300 antenna and/or the cellular booster omnidirectional antenna.

With the antenna taken care of (for now) I disconnected the coaxial cable for the X-50 from the radio side of the lightning arrestor and positioned it so I could pull it back into the sump pump room.  From there I fed it into the ham shack, disconnected it from the radio, and coiled it up.  I uncoiled the new 20′ LMR-400 cable with the N-male connector end positioned so I could feed it through the corner of the ceiling in the ham shack (by the ground wire) and into the sump pump room.  From there I fed it through one of the 2″ conduits into the cable entry box.  Back outside I shaped the cable (LMR-400 cable is double shielded and stiff) and connected it to the radio side of the Morgan VHF/UHF lightning arrestor and closed the lid on the box.

Back in the ham shack I attached the PL-259 connector to the SO-239 socket on the back of the Icom IC-7000 GoBox.  I could have gotten away with a 16′ cable but the 20′ length gives me more flexibility with respect to equipment placement.  I turned on the IC-7000 but did not hear anyone on either the South Lyon 2m or the Novi 70cm repeaters so I turned it off.

I disconnected Mike’s Icom IC-2820H and set it aside to make space for the new Yaesu FTM-400DR/DE dual band mobile transceiver.  I moved the new coax to the new radio, powered it up, spent a few minutes configuring some basic things, and then listened to the South Lyon and Novi repeaters.  I tried calling them but was not triggering them so I knew the PL Tone was not set correctly.  I called Mike for assistance and left him a voice message.

Linda was back by this time so she came down to see the new radio.  We then went out to the bus to make our final decisions about upholstery fabric and window shade materials.  In the end we chose the Lambright Notion Linen fabric for all four chairs and the MCD B50 material for the dark out shades.  We brought all the samples back in the house and I e-mailed our choices to Josh at Coach Supply Direct.

I had an e-mail from Scott Neader (KA9FOX) at QTH.com requesting an admin login for the SLAARC WordPress website so I set that up and e-mailed him back.  I had the new radio on and was listening to a conversation on the Novi repeater.  It had just concluded when Mike returned my call.  He walked me through how to set up the PL Tone and Squelch Tone for both of the repeaters on the FTM-400.  We were then able to verify that the radio was working on both bands.

For dinner Linda made a salad and pan-grilled tofu with caramelized onions and barbecue sauce which she served open-faced on hamburger buns.  We had watermelon for dessert, which we have been doing a lot this summer.  I did not care for watermelon as a child but it has become a favorite summertime treat.  I had dropped a small lock washer while mounting the new antenna to the tower earlier so I went to Lowe’s to get a replacement and some spares.  On the drive there I got a call from XPO Delivery Service letting me know that the new refrigerator for the bus would be delivered to Chuck’s shop in Novi tomorrow between 6 and 8 PM.

At Lowe’s I picked up some 6mm x 1.0 Nylok nuts in addition to the lock washers.  I also got some grass seed patching mix, a few more bags of decorative broken brick pieces, and a hummingbird feeder with a red reservoir so Linda can use sugar water without red food coloring.  When I got home the odometer on my car read 100000 so I took a picture of it with my phone.  I then spread the patching mix over the bare dirt I had used to fill a hole and troughs left by the installation of the natural gas line to our house last September.  The rest of the evening Linda read and I worked on completing drafts of blog posts.

2015/06/30 (T) Three Score and Five

Leave a reply

Today was a milestone birthday for Linda.  We had our usual leisurely early morning with coffee, fresh fruit, and cinnamon raisin toast (from Metropolitan Baking) for breakfast.  We talked some more about our long-term ham radio plans and decided we would order one (1) of the new Yaesu FTM-400DR/DE dual band mobile radios and a slightly more powerful VHF/UHF base station antenna.  Our daughter called around 9 AM to wish her many happy returns of the day.  My Michigan Public School Employee Retirement System (MPSERS) health insurance shifted her to secondary, with Medicare as primary on June 1st, the first day of the month in which she turned 65.

The temperature was in the low 60’s when we got up at 6:30 AM.  The weather forecast for the afternoon had an increasing chance of rain and the possibility of isolated thunderstorms so Linda went for a mid-morning walk.  I headed to my office to order the radio and a Diamond X-300NA 2m/70cm antenna.  All of the online distributors are selling the radio for the same price.  I decided to buy both products plus the RTSystems programming software, from Amateur Electronic Supply (AES).  Their UPS Ground shipping is “free” and since they are based in Ohio the shipment will be here in 1-2 days rather than 4-5 days.

I took a break and spread three more bags of brick pieces around the base of the tower and in front of the cable entry box.  Back in my office I dealt with some personal e-mail.  I sent an e-mail to Scott (KE9FOX) at QTH.com with additional information he needed to transfer the SLAARC website and domain name registration from GoDaddy to QTH.com.  I then gathered up a load of laundry and put it in the washer.

By the time that was all done it was getting close to lunch time.  Lunch was a big spinach and lettuce salad, baby carrots, a few sourdough pretzel nibblers with roasted red pepper hummus, fresh sweet cherries, and the blueberries/strawberries/raspberries that were left from breakfast.

After lunch I transferred the laundry to the clothes dryer and then got cleaned up.  We left around 3 PM for the U.S. Bar and Grill in Wayne and stopped on the way to get a card.  Today was John Smallwood’s last day at Wayne RESA and there was a gathering from 3-to-6 PM to see him off.  John was the VP of the Wayne County Salaried Staff Federation (WCSSF) and succeeded me as President of the local when I retired.  Now it was John’s turn to enjoy a well-earned and well-deserved retirement.  This was the second gathering for a colleague in the span of just over a month.  Besides wishing John well it was an opportunity to reconnect with other former colleagues.

After a suitable amount of time visiting at John’s party Linda and I drove to the Mongolian Barbecue in Novi for a celebratory birthday dinner.  It is a very noisy restaurant but was not as bad on a Tuesday evening as it was the last time we were here on a Saturday.  I would have preferred a quieter and more relaxing atmosphere, but the Mongolian Barbecues have a lot of ingredients that we can eat and we find the method of preparation very much to our liking.  By the time we had a small bowl of soup, a moderate sized salad, and a good size bowl of ingredients we were full.

I had a brief QSO with Chris (K8VJ) on the drive home.  I stopped at the Shell station and topped off the gas tank in my car so we would be ready to go in the morning.  We finally got home at 8:30 PM.  Linda made some hot tea and we each had a piece of Prickly Pear Cactus Jellied Candy.  I restarted the dryer on Touch Up and checked my e-mail.  We were tucked in by 10 PM as we needed to be on the road by 7:30 AM tomorrow.

 

2015/06/28 (N) Field Day Teardown

I was up at 7:15 AM and showered.  The rain finally cleared out leaving blue skies but with scattered white clouds still blowing across the region on brisk winds out of the NNE.  Linda was up by 8 and got the fresh fruit ready for our breakfast cereal while I made the coffee, which we enjoyed in the living room to warmth of the natural gas fireplace.  I did not expect to be using the fireplace this time of year but we have the furnace turned off, and are still getting overnight lows in the 50’s, so the fireplace is an effective and charming way to alleviate the slight morning chill in the front of the house.

I finished up the draft of my blog post for yesterday and started on this one while I drank my coffee.  By 9:45 AM I was ready to install the #6 green coated ground wire I bought last night.  I also decided to switch out the coax from the cable entry box (CEB) to the ham shack.  Linda had made a grocery list and left to do the shopping.

Outside I opened the CEB and disconnected the current VHF/UHF coax and let it slide back into the sump pump room (SPR).  Inside I removed the suspended ceiling tile in the northeast corner of the ham shack and routed the ground wire over the wall into the SPR.  I fed it through an existing cable tie on the bottom of one of the floor joists and through the outer wall into the CEB.  I had an unused copper ground lug and used it to connect the ground wire to the lower right mounting stud for the CEB copper backplane.

Back inside I uncoiled a length of 50 ohm coax that I borrowed from Mike (W8XH) and followed the same path as the ground wire.  Outside at the CEB I installed an N-male/SO-239(F) adapter onto the PL-259 connector on the end of the coax and attached it to the N-female socket on the lightning arrestor.  I was finished working in the CEB, closed the cover, and went back to the basement.

I decided to install the 36″ copper ground bar on the wall behind the ham shack desks just below the 120 VAC outlet strip, which required me to move the desks away from the wall.  I attached the end of the ground wire to one of the studs by spreading the strands and placing them under a washer and wing nut.  I need to get another copper lug to do this right.

I had a five foot length of braided tinned copper strap and used it to connect the ground terminal on the Go Box to the ground bar.  I spread the braid apart to make a small hole near each end, slipped the holes over the studs, and clamped them under washers.  This was a temporary arrangement for testing purposes.  I need to configure a length of #10 copper wire with a ring terminal on one end and a make spade connector on the other but did want to take the time to do that today.

With everything hooked up I called Mike (W8XH) to see if he was available for a quick radio test.  He was still at home and about to leave for the SLAARC Field Day site but gladly delayed his departure long enough to help me test the new configuration.  The result was a better send and receive signal on 2m, both direct and through the South Lyon K8VJ repeater, with an S3 received signal strength with the pre-amplifier turned on.  The direct signal was also a little better on the 440 MHz band but my received signal from the Novi repeater was still weak and noisy and my transmit signal was still not strong enough carry the repeater.

I had planned to leave around 11AM for the SLAARC Field Day site but wanted some lunch before I left.  I had just made a sandwich and was gathering up my equipment when Linda got back from her grocery shopping.  By the time I left it was past noon.

I was interested in our ham radio club’s participation in this year’s ARRL Field Day event but neither Linda nor I had had any need or desire to operate radios.  I worked all day Friday on the setup of the towers and antennas and helped a bit last night with the emergency teardown of the VHF/GOTA canopy.  The 24-hour Field Day operating window closed at 2 PM today but some of the teardown began before that time and I wanted to be there to help.

Some teardown was already underway when I arrived at the SLAARC Field Day site and lunch was also just being served, so everyone took a break to get something to eat except Steve (N8AR).  He was sitting in his car making contracts on the six meter (6m) band using the mobile radio in his car.  He had connected it to the 6m beam antenna on top of the big tower.  The 6m band is known as “the magic band” because it will suddenly “open” and allow very clear communication over great distances and then just as suddenly close.  It had apparently opened up this morning from the Mississippi River to the East Coast and south into the Caribbean.  One of our members made a contact with someone in the Dominican Republic.  While I was watching and listening I heard calls coming in from South Dakota and New Mexico.

This is the fourth year that Marianne Roney, the wife of one of club member Ed Roney (KD8OSM), has taken care of the Field Day meals, which include lunch and dinner on Saturday and breakfast and lunch on Sunday.  The meals are $5 per person per meal, which is a bargain for the variety and quantity of things she prepares and provides, except that there is typically very little we can eat.  She would make special provisions for us if we asked (she did the first year) but it is extra work for her and we are still left with not being able to eat most of what is available, so we do not purchase meals.

Operating stations are often staffed by two people, one operating the radio (left) and the other logging the contacts (right).

Operating stations are often staffed by two people, one operating the radio (left) and the other logging the contacts (right).

As the operating event was drawing to a close the computer in the 40m tent shut down.  The computers are not used to operate the radios, but are connected to them and are used to log the contacts using the N1MM Logger+ program.  The program reads key information about frequency and mode from the radio so all the logger has to capture are call sign, operating category, and section.  (Club member Larry, K8UT, is a member of the N1MM Logger development team.)  Every radio was paired with a laptop computer running this program, and the computers were all linked together via Wi-Fi.  As a result, the operators/loggers at each station could see all of the contacts that were being made regardless of which station made the contact and each computer contained a complete list of contacts.  The program also flags “dupes” (duplicate contacts).  In a contest situation this allows the operator to see that they have already worked that station on a particular band and mode and not spend time working it again on the same band and mode as duplicate contacts do not contribute to the contest score.

Just as it had started 24 hours earlier, at 2 PM it was all over without any fanfare.  The radios and computers were shut down and then the AC power generator was shut down.  Cords were unplugged, coiled, and staged near the vehicles they would eventually be loaded into.  Radios and computers were carefully disconnected, boxed (in some cases) and carried to the vehicles of their respective owners.  Tarps were pulled from the tents and folded and then the tents were collapsed and folded.  Four of use took down the 40m crossed dipole (inverted V) antenna and then took down the small support tower and disassembled it.  A larger crew eventually lowered the bigger tower, which required a winch, until it was resting in a step ladder.  This was necessary because of the two beam antennas at the top of the tower.  They removed the 6m and then the 20m beam antennas and then lowered the tower to the ground.  Part of the crew disassembled and packed the two beam antennas while the rest of them took the tower apart

We were essentially done with the teardown by 4 PM.  The teardown is always much faster than the setup and yet it was very relaxed and went very smoothly.  In spite of weather challenges all day Saturday and overnight into Sunday, and the disappointment of not having all of our stations on the air due to losing tents to the wind, we had a beautiful last day for the event and teardown.  Blue skies, white puffy clouds, cool temperatures, lighter breezes, and low humidity combined with a sufficient number of competent, helping hands, made for easier work for everyone.  The group stood around reflecting on the event and everyone was in a good mode, a sure sign that the 2015 ARRL Field Day had been a success for the South Lyon Area Amateur Radio Club.

I was the last one to pull out, right behind Steve who was towing a fully loaded enclosed trailer with a lot of the club’s equipment in it and on it.  We chatted via the South Lyon repeater on the drive home, our last radio work for the day.  I was home by 5 PM and just relaxed until dinnertime, tired from the sun, fresh air, and work.  For dinner Linda made a potato and spinach curry dish that she found in her Indian cookbook.  She also steamed some asparagus that she bought at the Howell Farmers Market this morning.  We had a quiet evening of reading, writing, and games before turning in at 10 PM.

At 5 AM I was vaguely aware of the sound of rain.  The cats were chasing each other through the house so I got up to make sure nothing was amiss, such as another mouse.  They were just having a bout of morning friskiness.  I added a little food up to their bowls, which drew their attention, and went back to bed.

I finally woke up and got up about 8:15 AM and got dressed in a suitable manner for today’s American Radio Relay League (ARRL) Field Day event.  The temperature was in the mid-50s, overcast and raining with blustery winds; not exactly the nice summer day we were all hoping for.  Some of the members of the South Lyon Area Amateur Radio Club (SLAARC) were gathering for breakfast at the usual place (Senate Coney Island) at the usual time (8 AM) but we obviously did not join them today.

I went to my office to retrieve my Sony DSLR and decided to turn on our Icom IC-7000 ham radio.  I had it tuned to the SLAARC (K8VJ) repeater in South Lyon when Keith, KD8YYJ, announced his presence.  He was driving from the west side of Howell to Wixom and seeing what repeaters he could hit.  We chatted for 10 to 15 minutes and I invited him to stop by the SLAARC Field Day site at the South Lyon Township James F. Atchison Memorial Park.

I worked all day yesterday as part of the SLAARC Field Day setup crew.  There was more setup to do starting at 9 AM this morning but the setup mostly involved radios, computers, Wi-Fi networking, and power.  I was not in any humor to rush off into the clammy weather conditions, and Linda was up by this point, so we had breakfast.  She found some Silk brand ‘yogurt’ at Meijer’s last week so we had that.  It was OK.  It is a creamy style yogurt, which is not my preference, but it was tasty enough.  Bananas, cinnamon raisin bread, and juice rounded out the meal.  Linda even made the coffee.  I turned on the natural gas fireplace to ward off the chill in the living room where we lingered and enjoyed our morning brew.

I finally left for the Field Day site around 11 AM.  The operating event started at 2 PM but the first of four meals was lunch today at noon and I wanted to capture photos of the rest of the setup and the lunch event.  It was raining lightly when I arrived and continued to rain until I left at 2:15 PM.  In between arrival and departure I took some photos and helped out a little bit, but there were plenty of people there taking care of what needed to be done.

Mike (W8XH) brought his Icom IC-2820H dual band mobile radio and several lengths of 50 ohm coax and we transferred those to my car.  He then walked me through the various menus and functions his new Yaesu FTM-400DR/DE radio, a dual band (VHF/UHF) 50 Watt rig with digital voice capability and a color touch screen display.  A group of SLAARC members recently purchased a Yaesu DR-1X repeater that works with the new Yaesu digital voice and data modes in addition to the traditional FM mode and are testing it as a replacement for the current, and very old, K8VJ repeater.

Mike’s IC-2820H is available for $350 but the FTM-400DR has a $100 rebate through the end of June, bringing the price down to $500.  As much as I would like to have a VHF/UHF radio in my car I am looking at one of these radios to install in the cockpit of the bus so we can use it going down the road.  The long-term plan is to put the Icom IC-7000 HF/VHF/UHF radio in our towed vehicle and get the Hi-Q 80-6 antenna mounted and operational in addition to the Diamond SG-7900 VHF/UHF antenna that is already on the Honda Element.

For base station use I would like to get an Elecraft K3s or Flex SDR rig.  The K3s has become the rig of choice among the members of the SLAARC who are serious about working HF and contesting.  Either of those are radios that could be fairly easily moved from the house to the bus when we travel.  Antenna options in the bus could include running coax to the Hi-Q on the toad and/or a “flagpole” HF vertical that is mounted using the towbar receiver or a base stand that goes under one of the tires.  An antenna switch would allow the use of the VHF/UHF antenna that was already installed for the cockpit radio.  All of these “base station” options would obviously be for stationary use only.

I uncoiled the coax cables that Mike lent me to see how long they were.  There was a 5 foot piece that was too short for what I needed, and a piece that was approximately 40 feet, which was longer than I needed.  The third piece was at least as long as the 40 footer.  I “tagged” his coax with small white cable ties so I could identify them later and return them to him.

I did not want to mess around switching coax cables in the rain so I unboxed Mike’s Icom 2820 and got it set up to use with my existing antenna and transmission lines.  I spent a little time with the manual and then powered it up.  It was already configured from when Mike used it in his ham shack so I did not need to do any setup to use it.  I monitored both the South Lyon 2m and Novi 440 MHz repeaters and was able to “hear” both of them, although the South Lyon signal was much better (stronger, quieter, clearer) than the Novi.  A couple of SLAARC members were on the South Lyon repeater taking care of Field Day business.  I waited a suitable amount of time after they were done and called for Mike (W8XH) and he came back right away.

We repeated the testing we had done last night.  The performance with the 2m South Lyon repeater seemed to be much better but the performance on the 70cm Novi repeater was the same or worse with a fading component to the noise.  I think we were on the air 15 to 20 minutes.  Based on the test results from last night and this afternoon I think I have two separate issues that are probably interacting; the IC-7000 needs to be grounded and the 25 feet of coax from the cable entry box (CEB) to the radio (Go Box) needs to be shorter and much higher quality.  I need to install the ground bar on the wall behind the ham radio desks and then purchase a suitable length of ground wire and run it from the CEB to the copper ground bar.  I will also need to get a 15 foot length of 50 ohm LMR-400 coax from Scott (AC8IL) with an N-male connector on one end and a PL-259 connector on the other end.

Linda prepared our dinner at 5 PM.  She made corn-on-the-cob and “cowgirl steaks,” a new (to us) vegetable protein product she found at Meijer’s.  After dinner we drove back to the SLAARC Field Day site to socialize with club members at dinnertime.  The weather at our house was still rainy with light-to-moderate winds and occasional stronger gusts.  We arrived at the Field Day site to find a flurry of activity and strong, steady winds out of the north with continued sporadic rain.

The small red tent that was originally supposed to be the VHF tent was nowhere to be seen and at least eight people were engaged in trying to control and fold up the large canopy that the club purchased yesterday at Costco to serve as the combined VHF and GOTA tent.  We quickly learned that the small tent, which was not being used, had collapsed and the large tent, which was unoccupied but full of radios and computers, had come unstaked and blown over in the wind.  Those who were not helping with the equipment canopy were gathered in the food canopy.  I pitched in on the equipment canopy rescue and Linda took the camera and joined the folks in the food tent.

After gathering up all of the pieces of the canopy and getting them back in the trailer some of the team added extra ropes and stakes to the windward end of the food canopy and both the 20m and 40m tents.  Another part of the team, including me, got Marty’s (KB8JIU) satellite tracking equipment out of the screen room, which had been draped with solid plastic tarps to keep the rain out, and then took the room down, disassembled the legs, folded it up, and stuffed it in the trailer.  The red tent was stuffed under a picnic table that was in the screen room so I grabbed that and put it in the trailer.  The support pole for one end of our off-center-fed dipoles was bending over to the south more than we liked.  Steve, N8AR, tied a rope around the existing rope, which was inline with the antenna and being used to keep it taught.  He slid the second rope up the first one as far as he could get it to go and then pulled it out to the northwest (the antenna was oriented east-west with the tension rope running east off of the east end).  He pulled it out until the support pole was reasonably vertical and I staked it down.

The winds really howled out of the north driving the rain before them. This shelter (from Costco) did not survive along with another tent and a screen room.

So the bad news was that some of our Field Day setup had not survived the weather which had not even reached severe conditions.  The good news was that our generator was still producing power, all of our towers and antennas were intact and functional, we had our two key stations on the air, and our food canopy was full of people and hot food.  Not the Field Day everyone had hoped for, but a great opportunity for teamwork and camaraderie and a learning experience to be sure, even if it was not the kind of lesson we wanted to learn.

We left around 7:30 PM and went to the New Hudson Lowe’s, which was very close to our Field Day site, where I bought 18 feet of AWG 6 stranded copper wire with a green sheath.  As soon as the weather improves I plan to run this from the CEB to the ham shack and use it to connect the ground bar in the shack to the copper backplane (ground plane) in the CEB.  I will then connect the ground on our Go Box (Icom IC-7000) to the ground bar and see if it helps with my noise issue.

Back at the house Linda wanted to watch an episode of NCIS Los Angeles, which we can now do thanks to our new OTA TV antenna.  We then watched an episode of Christina Cooks, Christina Perillo’s vegan cooking show from a decade ago.  These are still relevant and useful episodes and we especially enjoy them having seen and met her and her husband Robert on our two Taste of Health Holistic Holiday at Sea vegan cruises.  Linda read and I wrote for a while before lights out and off to sleep.

 

2015/06/26 (F) Field Day Setup

Leave a reply

I was up at 7 AM and ready to leave for breakfast with the other SLAARC members who would be setting up our temporary field site for the ARRL Field Day event.  I called the SLAARC repeater and Steve (N8AR) came back and wanted to know if I had the site use permit from the township?  No, I did not.  Paul, N8BHT, got on the air and said he gave it to Linda so I went back home.  Linda was up but had no recollection of receiving it.  We looked through the materials she got from Paul but could not find it.  I left again for breakfast but after more radio QSO went back a second time to retrieve all of the records and bring them with me to the field day site.  (Our best guess is that he gave the permits to the other Linda (NF8C) who is the club secretary.

By this time it was too late to make it to breakfast so I stopped for coffee and fueled my car.  Mike (W8XH) also did not go to breakfast with the group in South Lyon so we were the first to arrive at the site.  Another 10 guys showed up shortly thereafter.  John’s Sanitation then arrived and dropped off our rented porta-potty.

We had 12 people for most of the day and 14 total who were there for at least part of the day.  It was a good group and just the right size for the task.  We worked steadily from 9 AM until almost 5 PM except for an early afternoon lunch break.  By the end of the day we had erected two towers and set up six antennas (20m beam and 6m beam co-located on the taller tower, two off-center fed dipoles from the taller tower, a 40m crossed dipole from the shorter tower, and a 40m 1/4 wave vertical with four elevated counterpoise wires).  We also put up three radio tents, a screen room, and the big food tent.

The weather was cloudy and dull and not the best for taking photographs but I took pictures anyway.  I had to be deliberate in my shot selections, however, as both of my memory cards were almost full.  All of the work that needed to be done today was finished by 4:30 PM and most of us took off.  Our Field Day chairman, Paul (KD8SNZ), and a new member, Ron, setup their tents as they would be spending the night and keeping an eye on the site.  Steve (N8AR) and Eric (K8ERS) stayed a bit longer to test the antennas using the mobile radio in Steve’s SUV.

Back home I took a nap for an hour before dinner.  Linda grilled Portobello mushrooms and corn on the cob and cut up some fresh strawberries and cantaloupe.  After dinner I went to my office and transferred all of our recent photographs from the Sony alpha 100 DSLR to my computer and then to our older NAS device which we had with us this past winter.  I then started backing up all of the photographs we had taken since December 2014 from the old NAS unit to the new one.  This involved a significant number of images, a lot of gigabytes of data, and took a bit of time.

Rather than sit around waiting for file transfers to finish I decided to turn on the Icom IC-7000 ham radio and see if I could figure out why I could not hear the Novi 440 repeater on Wednesday when we tested the antenna and coax installation.  I checked the Nifty guide for the Icom IC-7000 and, as Mike had suspected, I did not have the Tone Squelch frequency set correctly for the Novi repeater.  I changed the mode on the 440 MHz band from ‘Tone’ to ‘TSQL’ and then caIled Mike (W8XH) on the phone to see if he could help me do a radio check.  We spent about an hour going back and forth between the Novi and South Lyon repeaters.

With the correct settings I was able to work both repeaters although I had a lot of background noise (static).  I played with the noise reduction (NR) and pre-amplifier functions and both seemed to help.  Mike tried various combinations of power and simplex operation and we determined that the basic problem seemed to be a weak signal in both directions.  I am still suspicious of the fact that I do not have the Go Box grounded as I vaguely recall from three years ago having noise problems with this setup until I grounded the box, which is tied to the radio ground.

Mike was suspicious of the coax I used to go from the lightning arrestor to the radio but looked up the specifications on my Diamond X-50N antenna and suggested that an antenna with more gain might be in order.  We also discussed the location where I placed the antenna on the tower.  Although most of the antenna is above the tower it is on the northwest leg.  The two repeaters lie to the southeast so the tower may be ‘blocking’ some of the signal although that does not seem likely to me.  Of more concern to me is that I mounted the base of the antenna so that two of the three counterpoise (ground plane) rods are even with, and parallel to, two of the three topmost crossbars.  If anything is being blocked it is likely those as the crossbars are between the rods and the repeater locations.

Ed (KD8OSM) jumped in briefly to let us know that I also had a ‘hum’ that sounded like the 60 Hz power line frequency only higher pitched.  I have a small fan installed in the back of the Go Box so I hummed the same pitch as it was producing into the microphone and both Ed and Mike confirmed that this was the tone they were hearing.  The fan is audible, but not that loud, and was two feet behind the microphone so I would be surprised if it was picking up the fan noise.  It is possible that the fan is inducing the hum electrically, but I believe it is a DC fan, so that seems unlikely.  I do not have an AC line filter installed on the fan, or anywhere in the box, so that may be a next step.

The larger of the two towers is up and secured. It has a 6m beam antenna on top of 20m beam antenna on a common mast with a rotator. We also attached one end of an off-center-fed dipole to this tower.

It has a 6m beam antenna on top of 20m beam antenna on a common mast with a rotator. We also attached one end of an off-center-fed dipole to this tower.  Tents are being erected to house the various operating stations.  The weather was overcast and forecast to get much worse before Field Day as over on Sunday.

Mike and I wrapped up our QSO and I shut the radio off.  I checked my e-mail and saw that the May 2015 issue of Bus Conversion Magazine was available.  I logged in to the website and downloaded both the standard and high definition versions of the April and May digital editions.  By the time I got to bed it was well after 11PM.  I finished up yesterday’s blog post draft and outlined as much of today’s post as I could before I lost the sequence and details of the day’s events.

 

2015/06/20 (S) Cable Entry Box

Leave a reply

We had not been to our local ham radio club breakfast the last two Saturdays because of the GLAMARAMA rally and a visit from Linda’s brother, Ron, and his wife, Mary.  The club was conducting VE testing today, rather than the usual 4th Saturday of the month, because the ARRL Field Day event is next weekend.  When we got to breakfast at 8 AM there were already a lot of people there and seven more came in after us.  We did not take a head count but it was somewhere between 25 and 30 people.  We also did not have our usual waitress but the substitute very efficiently got everyone’s order taken and delivered.

I checked with Mike (W8XH) and he is available to help us get the antennas mounted on the small tower on Monday or Wednesday, assuming I have the cable entry box (CEB) installed and all of the necessary coaxial cable on hand.  Getting the CEB mounted was my main goal for today, but not the first thing I had to do.  I called Chuck as we were leaving breakfast at 9:15 AM.  He was at home and suggested we stop by there and pick up a key to his shop.  He was working on landscaping when we arrived so we did not stay long and we were back home by 10 AM.  Linda finalized her shopping list and headed off to gather the things she needed to prepare tomorrow’s brunch.  I changed into my work clothes, gathered up the laundry, put a load in the washer, and got to work on the CEB.

The CEB is designed to mount on the outside of the house, allowing wiring to pass between the inside and outside of the house in a way that is weather tight and animal proof.  Coaxial RF cables and control lines enter through the bottom, connect to lightning arrestors in the CEB that provide a path to ground if/when needed, and then continue through the wall of the house and thence to various devices.  Those devices might include cellular phone signal boosters, Wi-Fi systems, TV sets, satellite receivers, personal weather stations, or amateur radio gear such as radios, remote antenna switches, and antenna rotators.

Superficially the installation looked simple.  With the copper back plane removed there were four mounting holes, one near each corner, and two large holes in the back.  All we had to do was hold the box against the wall, mark the locations of the four mounting holes and the big cable entry holes, set the box aside, drill the holes, put the box back up and secure it.  Right.  Sort of, but not exactly.  Mounting the box took seven hours to complete.

The first step was to remove the copper back plane with the three lightning arrestors installed on it.  I took care of that yesterday.  The next issue was that the house has shiplap siding, i.e., the east wall where I needed to mount the CEB was not a flat surface.  I decided to use 1″ square aluminum tube, installed vertically along the back of the box at the outside edges, to span multiple siding boards, ensuring that the CEB would be plumb.  I also decided to leave the tube long enough to go all the way to the ground and use it to support some the weight, in effect creating legs for the CEB.  That was Linda’s idea.  She’s a smart girl and a licensed amateur radio operator.

We had some surplus pavers and garden blocks and I found one that was just wide enough to catch the bottom of the legs.  I also had some left over paver base material, which meant I did not need to make a trip to the store.  The paver base material was from a project long, long ago (in a place far, far away) and I used it to create a base for the foundation paver, which was approximately 18″ x 12″.  I leveled the base side-to-side and pitched it away from the house for drainage.

Yesterday I purchased a 3′ long aluminum tube at Lowe’s and a 4′ long tube at The Home Depot.  Three feet turned out to be a good length, so I cut a foot off of the 4′ tube.  Things then got trickier.  The positioning of the CEB was critical as the two large holes in the back were for adapters for 2″ plastic conduit.  I was going to have to cut 3″ diameter holes through the bond that would come out above the plate on top of the concrete block foundation.  In the chosen mounting location the bottom corner holes in the CEB would be below the siding.  The lower right leg would be at least an inch away from the concrete block foundation and the lower left hole would be in front of a basement window opening so neither of these were going to be screwed into anything.

I wanted the CEB anchored at more than two points so I decided to drill two additional holes in the back, one on each side, approximately half way between the existing top and bottom holes.  I measured the spacing between the top and bottom holes as carefully as I could.  I measured down from the top end of each leg a distance for the top holes that was just sufficient to make sure the door of the CEB was below the 2″ iron gas pipe that runs horizontally along the outside of the house.  I measured down from there for the new middle hole and the bottom hole.  I then drilled the three holes through each leg by drilling opposing sides.  I had to use a powered hand drill for this work as my drill press was stored behind a large pile of RV furniture that we took out of the bus and was inaccessible.

I attached one of the legs to the back of the box using two short bolts through the top and bottom holes.  I then used the middle hole in the leg as a guide and drilled through the back of the CEB.  I repeated this procedure for the other leg.  I drilled the holes in the legs as accurately as I could but they did not quite line up so I had to enlarge them slightly by using the drill bit like a router bit.  Not ideal, to be sure, but aluminum is relatively soft and it worked.

I attached each leg to the back of the CEB using 1.5″ 1/4-20 bolts through the bottom corner holes.  I snugged these up but left them loose enough that we could move the legs.  The top and middle holes were located in positions that would allow lag screws to be screwed into the siding and underlying plywood.  We had to tilt the legs to get them under the 2″ iron gas pipe and then straighten them and set them on the foundation paver.  We had to do this multiple times but it was easy once we figured out how to do it the first time.

With the CEB in position I marked the location of the holes for four 3″ 1/4-20 lag screws.  We removed the CEB so I could drill the holes for the lag screws and then put it back in position and screwed it to the wall.  I marked the locations of the two holes for the conduit as best I could and then unscrewed the box and removed it again.  I used our 1/2″ Craftsmen corded drill for the 3″ hole saw.  I bought this drill in 1978, along with a lot of other Craftsmen tools, when we moved into our house in Farmington Hills.  I still have almost all of those tools and they all still work.

With the conduit holes drilled I cut one of the 18″ lengths of conduit in half, inserted the pieces into the adapters, and placed them in the holes.  We then put the CEB into position, got the adapters through the holes in the back of the CED, and tried to line up the holes in the legs.  The conduit was being forced up as it went through the bond, especially the one on the left, and would not allow the holes in the CEB to line up with the holes in the legs.  We took the retaining rings off of the adapters and removed the CEB, again.

I shortened the conduit pieces to approximately 5″ and checked the fit in the holes.  We wrapped two bands of adhesive backed foam weather-stripping around each piece of conduit and placed them back in the holes.  I then applied a bead of adhesive caulk all the way around each adapter at the wall.  We put the CEB in position for the final time, got the conduit adapters through the holes, snugged up the retaining rings, and put the four lag screws in.  After tightening the four lag screws I tightened the two bolts in the lower corners.  I then tightened the adapter retain rings and put the open end caps on.  The conduit ended up getting pulled back out of the wall a bit so I used the thin end of a 10″‘wood shim to try and force the caulk back into the gap around the conduit adapter.  It did not go back in very well so I will have to figure out something else to seal around the conduit.

The CEB was finally installed and very solidly anchored.  I got the copper base plate and remounted it to the five studs (four corners and one center) using some antioxidant/anti-seize compound on the stud threads.  The last step (for today) was to install the snap in covers for the 16 cable entrance holes in the bottom of CEB.  I also ordered 16 grommets and will remove the caps and replace them with grommets as I install devices and run their cables and wires into the CEB.

The two pieces of conduit open into the sump pump room (large closet) in the northeast corner of the basement just above the wood plate that sits on top of the concrete block foundation.  I plan to install the SureCall Fusion5s 5-band cellular booster (amplifier) in this room to keep it close to the CEB and because there is AC power available there.  I bought an installation kit for the Fusion5s that includes a lightning arrestor which will get mounted in the CEB.  I also bought an amplifier for the OTA TV antenna that will mount on the tower a few feet below the antenna.  The amplifier will get its power through the coax from a power inserter that doubles as a lightning arrestor and will be installed in the CEB with the AC power supply (wall wart) in the sump pump room.

I did not get these two additional lightning arrestors installed today.  By the time we got the CEB installed we were tired.  The high temperature was OK (near 80?) but the relative humidity was very high.  I was also very sore the whole time, especially my left knee, undoubtedly the lingering after effect of using the power chisel earlier in the week to remove thinset and mastic from the floor of the bus.  Getting down and up at least 50 times during the afternoon did not improve matters, but we got it done.

Even though she was also tired, once we reached a point where I could finish up alone Linda got busy making several food items for tomorrow.  In the midst of all that she heated some Amy’s Lentil Soup and made grilled cheese sandwiches with Diaya cheese or dinner.  Diaya makes an excellent non-dairy cheese that works well cold or cooked into dishes.

After dinner I returned a call from Butch to find out more about their new property and buildings, and discuss bus and ham radio projects.  One of the things Linda made was an apple pie so we stayed up until it was cool enough to wrap up.  That turned out to be 10 PM, by which time we ready to turn in for the night.

 

2015/06/16 (T) More Stupid

Linda was scheduled to go to the bakery this morning but rescheduled to tomorrow due to last night’s weather forecast and the possibility of flooded highways in Detroit.  The morning rush hour traffic is bad under the best of conditions and flooded roadways can make it near impossible.  She also did not sleep well and woke up tired.

The Apex roofing crew started showing up just before 8 AM and the Wimsatt truck showed up with the shingles a little after 8 AM.  They brought a conveyor truck this time and were able to get the shingles off the truck and onto the roof without difficulty.  The Apex crew did not waste any time getting to work.  It turned out to be a great day for roofing; clear skies, no rain, moderate temperatures, lower humidity, and some breeze.  Even so, it is work that is done without the benefit of shade and roofs are hot places to work even on the nicest of days.

Linda continued working on the financials for our amateur radio club while I checked my e-mail.  I had a reply from RV Critter Guard telling me what to order and how much it would cost.  I placed the order through their website and used PayPal to complete the transaction.  I tried calling the concrete contractor that Phil recommended (Bid Rite Concrete LLC in Whitmore Lake) but the phone would disconnect after the first ring and revert to a dial tone.  Perhaps the recent storms caused a problem but I e-mailed Phil to see if he had a different number for them.  I called the Henry Ford Medical Center in West Bloomfield and made dermatology appointments for myself and Linda.

With all of that taken care of I turned my attention to the bus.  The toilet is a Microphor LF-210.  It uses pressurized air to operate the waste valve and the water valve and to help push the waste through the drain pipe and into the black tank.  To remove the toilet I had to undo three connections—air, water, and waste—and take out the four screws securing it to the floor.  If only it was as easy as that makes it sound.

Undoing the air line was easy and undoing the water connection only a little less so.  The waste connection was another matter.  The 1.5″ black plastic drain pipe was routed from the water bay through the floor and into the HVAC chase that runs along the driver’s side of the coach.  The converter, Royale Coach, brought it out through a hole in the wood that covers the chase, making it impossible to take the wood cover off.  The pipe then made two right angle bends, the first one towards the floor and the second one towards the back of the toilet.  The waste pipe was connected to the toilet discharge pipe with a length of rubber hose and a compression sleeve.

The toilet has a large hole in the back for all of these lines to pass through to the inside where they get hooked up.  It should have been a simple matter to slide the toilet away from the wall/chase but the last bend in the drain line was below the top edge of the bottom of the hole, preventing it from coming out.  After wiggling the toilet enough to get the rubber hose loose from the drain pipe I was able to lift the drain pipe just enough to slide the toilet out.  I took pictures for a possible BCM article on our interior remodeling project and then Linda helped me move the toilet out of the bathroom to the front of the coach.

The more I disassemble this coach the more stupid I think the design and construction of its systems are.  I don’t know that coaches from Marathon, Liberty, Vantare, Featherlight, Parliament, Millennium, Custom Coach, or any of a dozen other companies that have come and gone, is any better as I have never tried to disassemble one of them.  These are one-of-kind vehicles that are custom built specifically for the original purchaser and the over-riding factor in every case is the interior design.  Stuff, like toilets, go where the customer wants it, and systems, which are generally buried and hidden from view, get built wherever and however they can be made to fit.  The converter does not expect to have to repair or replace anything during the very short 12 month, 12,000 miles, warranty period and if stuff breaks after that, or someone wants to do a remodel or upgrade sometime later, it will all be time and material.  How difficult it is to do, and how many hours it takes, is someone else’s problem at that point.

We had a call from Butch updating us on a possible property purchase.  They are waiting for a clear title search before making an offer.  The property includes a house and a sizable barn.  The barn needs a new roof and the house will have to be gutted and the inside rebuilt, but for the right price it will still be a good deal.  They already have a good estimate to replace the barn roof and since they are now retired they have more time to work on the house than they would have a year ago.  They also have family and friends who can help.  Besides, they still have their home/business building in Twelve Mile, Indiana and their bus, which they lived in all this past winter, so they will not be under any pressure to get the inside rebuilt quickly.

Linda started downloading updates from Adobe Creative Cloud, which take a very long time, and then left at 3:30 PM for Ann Arbor.  She agreed to take care of grand-daughter Madeline while Brendan and Shawna attended a reception at the University of Michigan – Ann Arbor for newly tenured and promoted faculty.  I was on my own for dinner and Linda bought an Amy’s pizza so I would have something easy to prepare.

The roofers finished up for the day around 5 PM.  By the time they left most of the trash was in their dumpster trailer and the roof was tarped as a precaution against rain even though the forecast for tonight and tomorrow is for dry weather.  Rain returns to the forecast tomorrow night into Thursday but turns dry again on Friday, so we are optimistic that they will get the job finished this week.  It’s a big job but Apex has a big crew working on it and they got a lot of work done today.  We are very pleased with the look of the Certainteed Landmark Pro Max Def Resawn Shake shingle that we chose.  I took pictures of the work throughout the day as I always try to do with major projects.

After the roofers left I worked for a while in the bus.  I took the mattress into the house along with the electric heating pad controls.  I disconnected the two gas struts that support the plywood bed platform so I could open it far enough to reinstall one of the drawers.  I left them disconnected as I plan to remove the platform to provide better access to the sides of the box and floor.  I also plan to reposition them when I reinstall the platform to provide better access to the storage area underneath.  I then took measurements and made a sketch of the file drawer box for the desk.

I cooked the Amy’s Roasted Vegetable Pizza on the outdoor gas grill, both to avoid heating up the house and to see how it responded to that cooking method.  I used the grilling mat and the result was quite acceptable.  A glass of Franzia Moscato was a nice accompaniment.

After dinner I worked at the drafting board in my office turning my sketch and measurements into a scale drawing.  The two boxes for the desk will be trickier than a standard desk box because of the HVAC chase and because I have to put an Aqua-Hot heat exchanger in the bottom of each one.  I worked until about 9 PM and then came back upstairs.

The air-conditioner worked fine yesterday but was once again unable to bring the temperature in the house below 74 degrees F even though the outside air temperature never rose above 80.  There is clearly something wrong and I am wondering if one of the cold air ducts is open into the attic and/or one of the return air ducts us drawing hot air from the attic.  Either of these conditions would reduce the air flow to the house and overtax the evaporator in the air handling unit.  The more likely cause, however, is lack of refrigerant.  Whatever the case I shut the system off and opened up the house.

I was relaxing in the living room when Linda called at 9:30 PM to let me know she had left her babysitting gig and was stopping at the Whole Foods Market before heading home.  The reception started at 5 PM and lasted until 9 PM.  She was home by 10:15 PM and straight away to bed as she has to go into the bakery tomorrow and wants to leave early enough to be ahead of the morning rush hour traffic.
