2015/11/03 (T) The Penultimate Cut

I heard noises in the kitchen at 7 AM and thought the cats might be up to something.  I got up and discovered that Linda was just leaving the house.  She is normally out the door between 6:15 and 6:30 AM but did not set her iPad alarm last night.  I stuck my head out the door and said “good morning” as she was getting in the car.

I had my usual breakfast of granola with fresh blueberries and brewed a half pot of Sumatra Mandheling half-caffe coffee.  I was enjoying my cup-a-joe by the fireplace when Linda called to let me know there was a story coming up on Michigan Radio (WUOM) at 8:30 AM about an underground landfill fire in Bridgeton, Missouri.  Bridgeton is where my sister, niece, future nephew, and grand-niece live and I had just heard about this fire for the first time on Sunday evening while talking with my sister.

I got the leaf blower out at 10 AM and spent a couple of hours blowing as many leaves out from under bushes and away from the house into the yard as I could.  Keith arrived at 10:30 AM and followed his usual mowing pattern starting with the west half of the property.  The lawn in the immediate vicinity of the house is the last area he cuts which gave me enough time to get the leaves out into the yard where Keith could mulch them.

Most of our trees have dropped most of their leaves by now and Keith’s mower did a pretty good job of mulching most of them.  Before he left we discussed having him come back one more time.  The grass has quit growing so my preference is to wait two weeks but that will depend on the weather.  Keith will check with us next Monday and we will decide what to do at that time.

Mike (W8XH) is planning to come over tomorrow after breakfast and help me work on the tower and our Hi-Q 6-80 antenna.  I have been collecting materials that I need and took a little time to see if they would work with the tower.  I also took the Diamond X-300N antenna down as I planned to put it on the tower in place of the X-50N that is currently up there.  My materials were not working quite the way I had hoped they would so I headed to Lowe’s to see what else I could find.  I also planned to drop off the used oil and filters from the bus at O’Reilly’s Auto Parts store.

At Lowe’s I found clamp sets designed for mounting antenna masts and bought a pair.  O’Reilly’s parking lot was still closed off.  It looked like it had been re-blacktopped and they were painting the stripes for the parking spaces.  This was my second attempt to get rid of the waste from yesterday’s bus maintenance.  I will try again tomorrow; with any luck the third time will be the charm.damage

I finally got back to work on the bus at 2:30 PM and removed the front passenger chair pedestal base.  The entire area under the base, between the side-to-side seat mounting channels, was rotten so I cut out the water-damaged wood.  Just below the wood I found rusted metal which appeared to be delaminating.  Metal does not do that so I presume there was a layer of sheet metal on top of a metal housing.  The main structure of the bus is welded stainless steel but mild steel was obviously used to create compartments.  Ugh.

After cutting out the damaged wood the remaining piece towards the outside was loose but would not come out.  I removed a couple of screws from the 1/4″ walnut veneer side panel and pried the top out with a small screwdriver.  This panel has a lot of switches mounted in it and a lot of wires behind it so I could only pull it out about four inches.  That was enough to see a 3/4″x3/4″ piece of blocking screwed to the floor to catch/secure the bottom edge of the panel.  It also enough to see a very large nest made of tiny bits of shredded paper.

The cavity behind the panel to the right of the co-pilot/navigator seat was apparently a great place for a mouse to build a nest.

I left the nest alone for the moment and removed two screws from the block that went into the piece of wood I need to remove.  It appeared that a drain line for the front air-conditioner went through the floor near the outside edge and possibly some wires.  I left the nest for Linda to see and will resume working on this tomorrow.

Linda made vegan grilled cheese sandwiches for dinner and served them with some of the leftover broccoli soup and sliced fruit.  We each had a small glass of the Frey Natural Red organic/vegan wine.

After dinner I called Phil to see what his plans were for this week vis-a-vis our driveway and French drain projects.  I got his voice mail and left him a message.  When we left on Saturday afternoon he was just finishing up placing and compacting the gravel in the driveway but said the west end of the yard needed to dry out (again) before he could finish working down there.  Hopefully the new drain will help speed that process along.

Phil uses a self-leveling laser level system to measure elevations.  Not only has he assured me that the new 40 foot parking area is level, he has demonstrated it with his system.  Still, it does not look level, especially from certain points of view, and it does not feel level when driving in it, although that may also be an optical illusion.  We have a transit level and I plan to use it to check the pad, but it requires two people, one to hold the measuring stick and one to look through the telescope and record the readings.  That means I need Linda’s assistance, which means this will have to wait until the weekend.  Perhaps by then I will have the cockpit in the bus repaired.  It’s also possible that Phil will have returned and completed the job, I which case I may have him help me use the transit as a check on his laser system.

We watched our usual lineup of Tuesday evening TV shows while Linda checked in on her online word games and I worked on this post.

 

2015/10/24 (S) Meghan and Chris

We drove separately to our SLAARC breakfast in South Lyon as Linda had plans to walk with Diane at Kensington Metropark after breakfast.  We drove through some heavy rain after which I chatted a bit with Tom (W8TAF) and Mike (W8XH).  As always, we enjoyed the breakfast conversation with our fellow amateur radio operators.  Linda left at 9:15 and I lingered until 9:30 enjoying my last cup of coffee.  I paid our check and had just headed for home when Mike (W8XH) called me on the radio.  We had a good chat about my Hi-Q 6-80 mobile HF antenna and will try to find a time to test it using his newer VNWA.  Mike has learned a lot about how to use it in the last couple of years and is always willing to put that knowledge to use to help his fellow ham.  I would love to figure out a way to mount this antenna so we can take it with us this winter and use it, but I doubt that will happen.  We just have too much else that has to get done in the next month that is more important than this.

At home I pulled up the DX Engineering website on my iPad.  I found their Mix 31 snap-on ferrite chokes and put them in my cart.  If I can find a few other small things to buy the order will qualify for free shipping.  I suspect that will not be a problem.

Next I pulled up the Sony alpha app and researched the acronyms they use for various features of their cameras and lenses.  The model numbers for their A-mount lenses all begin with SAL (Sony “A” Lens) and their E-mount lenses all begin with SEL (Sony “E” Lens) so that helps sort those out right up front.  However, they make both 35mm full frame (36mm x 24mm) and APS-C (24mm x 16mm) lenses in both mounting systems.  The FF lenses can be used on APS-C bodies, such as our Sony a100, but the APS-C lenses, which always include the letters “DT” in the product name, cannot generally be used on FF bodies.  Our new Sony SLT-a99v DSLT camera body, however, can detect a DT lens and automatically limits the active portion of the sensor to an APS-C size area.

SAM stands for “Smooth Action Motor” and SSM stands for “SuperSonic wave Motor” both of which are used with certain lenses, especially large telephoto ones, that have their own internal focusing motor.  OSS stands for “Optical Steady Shot.”  Even though the alpha series cameras have image stabilization built into the body some Sony lenses also have image stabilization built into them.

One of the things I was trying to find out is which lenses have distance encoders so they will work with the ADI (Advanced Distance Integration) feature of the a99 body and compatible Sony flash units.  The lens specification table in the alpha app was not really clear on this point.  Some lenses were marked with a small circle for this feature and others with a dash.  If their nomenclature is consistent with other entries the dash means “no”.  Logically then the circle means “yes” but I did not pursue this further.  I will have to experiment with the 18-70mm APS-C format lens that came with the a100 and see if it supports ADI.

I opened the B&H Photo Video app and revisited the reviews on the Sony HVL-60m flash.  Although more expensive than the HVL-43m I added it to my cart.  Besides being more powerful it has an available external battery pack which I found and also put in the cart.  Finally, I added the Cotton Carrier dual camera harness to the cart.  I found my Minolta electric shutter releases and checked to see if they worked with the alpha 99.  They did!, so I did not need to order new ones.  B&H was closed for online order processing until 7:30 PM this evening so I did not submit the order right away.  The Cotton Carrier is on sale until the 26th so I will submit the order tomorrow while the sale price is still valid.

Linda got home at 12:30 PM and we had the last two vegan hotdogs for lunch.  She then started preparing dinner and I went to my office.  I did a load of laundry, dealt with e-mail, checked in with RVillage, and copied photos from both the Sony a100 and the Sony a99 to my computer.  I updated my BCM article spreadsheet and then moved article folders to the proper directories and deleted them from my BCM Dropbox folder.  I added 80 pounds of solar salt to the water softener and then brought the laundry upstairs and hung it up.  By 4:30 PM I was feeling very tired and took a short nap until Meghan and Chris showed up at 5 PM.

We showed them the driveway and bus projects and then went inside the house just as it started to sprinkle.  Everyone selected a beer and we were standing around the kitchen when a brief, but very intense, line of storms moved through our area with heavy rain and strong winds.

For dinner Linda made a salad of dark leafy greens with tomatoes, carrots, mushrooms, and raisins dressed with a raspberry vinaigrette.  The main course was a Farro pilaf with dried cranberries, onions, garlic, broccoli leaves, and slivered almonds.  Yes, broccoli leaves.  The whole broccoli plant is edible but until recently only the flowerets were available in stores.  The side dish was Brussels sprouts cut in half and oven-roasted with salt, pepper, and a little olive oil.  Dessert was pears in wine.  She used the Witch’s Brew, a spiced red wine that was perfect for this dish and this time of year.  After poaching the pears she reduced the wine to a sauce and chilled everything in the refrigerator for hours.  (The pears were made ahead of time as was the Farro, with the main dish being finished just before serving.)

We sat in the living room with the fireplace on and chatted about houses, pets, travel, sports, and the upcoming holidays.  Meghan and Chris stayed until 8:30 PM and then headed home.  It was a nice visit during which both cats actually came out of hiding and allowed themselves to be petted, a rare treat in Jasper’s case.

We were both tired, partly the residual effect of our altered schedule on Wednesday and Thursday, so we finished clearing the table and went to bed.  The Detroit PBS Create channel was featuring vegetarian (including vegan) episodes of various cooking shows so we watched a few of those before turning off the TV and going to sleep.

 

2015/06/27 (S) ARRL Field Day

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.
