2015/06/25 (R) The Mouse

Brighton Honda called yesterday in the afternoon to get permission to do additional work on my car.  Since we plan to keep the car for a while, and then perhaps give it to our son, it was the kind of work that needed to be done regardless of the costs.  They called back later to indicate that they would not have it aligned before closing time.  That was fine with us as it would have been inconvenient to impossible for us to get there by 6 PM to pick it up.  Linda told them to call in the morning when it was ready.

It is amazing how attuned we become to routine sounds and how sensitive we are to non-routine ones, even (especially?) while sleeping.  So it was last night that I was suddenly aware that one of our cats was making a repetitive sound that was unusual.  I turned on my flashlight, hoping to not disturb Linda, and got out of bed.  Both cats were hunched down on the floor on Linda’s side of the bed with Jasper in front.  He was the one responsible for the sound and the reason was next to his head and about 3 inches away; a little dark gray mouse.

My first thought when I see one or both of the cats with a mouse next to them rather than in their mouth is that it is dead but that was not the case.  This mouse was alive and apparently not injured.  I have seen this behavior before in which the mouse basically “plays dead” and the cats leave it alone but watch it carefully.  Mice seem to know that cats are triggered by movement and that if they sit very still the cats just sit there and guard them.  It was 4:30 AM and I was not fully awake so I do not recall the exact sequence of events, but the mouse somehow ended up in our master bathroom.   I do not recall what I did with the cats but I think I went and got a box with high sides and tried to get the mouse to go in it and it made a run for it towards the bathroom.  Linda was awake by this point so she got a towel for me.  I went in the bathroom and used the towel to block the gap under the door and prevent the little critter from getting back into the bedroom while I tried to get it into the box.  I was unsuccessful and it managed to find a place to hide in the hot water baseboard radiator.

Linda got one of the live traps we recently purchased and baited it with the recommended saltine and peanut butter.  We set the trap near the radiator, turned out the bathroom light, shut the door, and tried to plug the gap with the towel from the outside, figuring we would deal with the mouse in the morning.  Juniper kept pawing at the towel and pulling it back from the door so we put both cats out of the bedroom and shut the door.  They found that confusing as they sleep with us and generally have the run of the house.  One or both of them pawed at the door meowing to get back in for quite a while.  It wasn’t the best night’s sleep we have had and the timing was unfortunate given the hard day of tower work.

Brighton Honda called at 8:01 AM to let us know the car was ready.  Hello, I’m awake now!  I checked on the mouse and it was now safely tucked away on top of the radiator fins inside the housing where neither the cats nor I could get to it.  We decided to leave the live trap in place, sealed the gap under the door, and kept the bedroom door shut to keep the cats out.

I had planned to drive to Isringhausen’s U.S. headquarters in Galesburg, Michigan today but first we had to get my car.  As long as we were headed that way we decided to go to the Brighton Panera for coffee, but had toast and juice for breakfast at home before we left.

The 100,000 mile service is extensive and includes changing the spark plugs.  Beyond the routine service items the Element needed a new ball joint and tie rod and had a stuck brake caliper pin that had to be repaired.  Given the front end work I also had them align it.  Butch and I rebuilt the front brakes last year so I was surprised that there was an issue with them, but the car has been towed and driven in some harsh environments since then so that may have been a factor.

The Panera at Grand River Avenue and I-96 is not one of our favorites.  More often than not we end up with coffee grounds in our cups and the bathrooms are not maintained as they should be.  Today was not the first time we have been to this location that the men’s restroom was out of toilet paper.  It is also often freezing cold inside the restaurant and today was no exception.  The weather was overcast and a bit gloomy but the outside temperature, while not warm, was much more comfortable than inside.  We were also unable to connect to their Wi-Fi signal, which is generally useable.  That’s pretty basic stuff to not be able to get right and falls squarely on local management in my opinion.

While we drank our coffee I called Rick Short at ISRI to make sure he would be in but I got his voice mail again.  I asked for a call back but never got one so I did not make the trip to Galesburg.  Apparently they have better things to do than be of assistance to me.  I only want to buy one chair, not a fleet of chairs, so I understand my relative unimportance, but I don’t like it just the same.  We decided to spend the day at home completing the work from yesterday, which had made a mess throughout the house.

One of the things we needed to do was register our cellular booster system.  Given that it is a five band device I was not clear on whether we had to register it only with Verizon or with all of the carriers.  I called the company we bought it from, Cellular Solutions, and talked to Judy who said we only had to register it with the carriers we personally use.  For us that is Verizon Wireless.  Registration was via the Verizon Website and was simple enough.  It did, however, require me to log in to our My Verizon account and navigate through a couple of screens to a page where we could enter the information from the label on the box.  The serial number was on two peel off tags, so one of those went on the booster and the other one went in the manual.

With the unit registered I turned the power switch on and watched the ‘Alert’ lights all go solid yellow.  As I mentioned in yesterday’s post solid yellow lights are not described anywhere in the manual.  I called Cellular Solutions back and said I had a technical support question.  The woman on the phone took my name and number and said someone would call me back.

Since I was apparently taking care of phone chores I decided to call Universal Towers and inquire about their B-30 base.  The woman who answered the phone never gave her name but was able to answer some questions.  She indicated that their base might or might not be compatible with older Heights Tower products, depending on exactly which product I had, and that I would have to talk to the owner, Bill, who wasn’t there at the moment.  She did know that the outside-to-outside measurement of the legs on a B-30 base was 30 inches and the base cost $290.  She also told me that the larger bases, like the B-30, consisted only of the three rods with the mounting yokes on top; the three rods were not otherwise connected together in any way.  She also confirmed that the ‘U’ shaped yokes at the top of the base rods were welded on and not adjustable.  The normal installation procedure involved connecting them to the bottom of the legs of the first section of the tower, setting them in the hole as the concrete is poured, and adjusting them by moving them around until the legs of the tower were plumb.  That sounded to me like a process where a lot could go wrong and not be repairable.

I pulled a 75 ohm coax out of the ceiling of the basement yesterday.  We laid it out in the basement to see how long it was and it looked to be at least 60 feet.  Linda suggested we test it before running it through the basement ceiling which was a very sensible idea.  I unplugged the power adapter for the TV amplifier power inserter, detached the coax that feeds the TV in the bedroom, attached the downstairs cable, and connected the other end to the basement TV set.  Linda set up the TV for Antenna input, did an All Channels scan, and got the same stations we got yesterday, minus a couple.

In spite of what appeared to be acceptable performance I decided I wanted a new coax cable and Linda wanted to return three of the ropes I bought at Lowe’s but never used.  She found the receipt and we went to Lowe’s.  They had a good quality RG-6 quad-shield coax (75 ohm) in various lengths including 50 feet, which is what I needed.  At the register I decided to buy two more 40 pound bags of solar salt.  I am not an impulse shopper as a rule but their supply of Morton Solar Salt was very low and stocking up seemed like a good idea.

We stopped at Teeko’s to order coffee.  Mary took our order and rang it up; one pound each of the three different half-caff blends that have become our standard.  We took note of the fact that the Bennigan’s restaurant building on the northwest corner of Grand River Avenue and Latson Road was gone and a sign said a Panera would be coming soon to that location.  We didn’t say anything to Mary, but that cannot be good news for Teeko’s.  We will continue to buy our custom roasted beans at Teeko’s as long as they are open but it is going to be difficult for them to compete with a $2.25 cup of bottomless coffee, free Wi-Fi, a restaurant, a bakery, drive through service, and ample parking with great access to I-96.

When we got home I checked the live trap in our master bathroom and we had captured the mouse.  We took the trap to the northeast corner of the property, towards our neighbor’s pond, and set it free.  It did not want to leave the trap and I had to encourage it to go.  Once it hit the ground, however, it scampered away looking for a place to hide.

We then worked on running the new coax from the basement TV to the sump pump room above the suspended ceiling.  I disconnected the power inserter for the amplifier and disconnected the old coax we had tested earlier.  I notched a ceiling panel at the corner of a boxed support column behind the basement TV to allow the ceiling tile to go back into place around the coax.  We then installed one of the wire channels to contain and hide the coax from the ceiling down to the TV set and connected it to the back of the set.

In the sump pump room I attached the coax from the cable entry box (CEB) to the input of the new 1-to-2 signal splitter.  I attached the coax for the bedroom TV to one output from the splitter and the coax we just ran to the other output.  I mounted the splitter on the wall of the sump pump room and secured the cable coming from the CEB to the ceiling.  I then plugged the power supply for the power inserter back in to an AC outlet.  Linda scanned for channels and verified that everything was working correctly.  We then installed the other wire channel alongside the trim on the bedroom doorwall to route and hide the cable coming up from the basement.

I continued to fuss with the cell phone booster gain settings.  We had not gotten the promised return phone call from Cellular Solutions Technical Support so I called them.  I got Judy again and explained what I was seeing with the solid yellow lights.  She checked with her tech support people and they said the manufacturer (SureCall) told them the solid yellow was the same as the blinking yellow; that the booster was adjusting the gain and it was “normal.”  The manual says that normal is when the light is off, so I’m not sure I buy this explanation, but based on that I left the booster turned on.

With all of that done we started cleaning up the tools and materials we had scattered over two floors of the house.  I decided that was also a good time to start a load of laundry, although it was actually rather late in day for that.  I did three loads by the time I was done and it was sometime after 10:30 PM before the last load was dry.  I needed to be up at 7 AM to be at breakfast in South Lyon at 8 AM as our SLAARC group would start setting up for the ARRL Field Day event at 9 AM.

 

2015/06/24 (W) Up The Tower

Today was the day to finally climb the tower to remove an old TV antenna, reposition an amateur radio antenna, and install two new antennas, one for OTA TV and the other for a cellular booster system.  But there were other things to do before I was ready to climb.

I was up at 7 AM and on my way to Lowe’s in Howell by 7:20 AM in search of a solution to the problem of how to mount the outdoor cellular booster antenna.  I ended up buying two 2-1/2 inch U-bolts.  Although the tower legs are 1-5/8″ in diameter the angle bracket attached to the bottom of the antenna is 2-1/4 inches wide.  Thus I needed the 2-1/2 inch spacing for the threaded ends of the U-bolt to clear the bracket.

Back at the house Linda was up and had the coffee made.  We had a quick breakfast of homemade granola.  I removed the tire pressure sensors and GPS from my car and headed to Brighton Honda to drop it off for its 100,000 mile service appointment.  Linda arrived at the dealership about 10 minutes later.  We then headed to Adams Electronics in Wixom.  While Adams Electronics primarily serves the public and business communications markets owner Scott Adams, AC8IL, is a long-time ham and a member of the South Lyon Area Amateur Radio Club and Novi Amateur Radio Club.  Well known in the local amateur radio community, Scotty is the local go-to guy for certain kinds of equipment.  I ordered two coaxial cables from him the other day and we were here to pick them up.

We left to return home at 10 AM so I called Mike (W8XH) to let him know we were running a little behind.  So was he, but thought he could be at our house by 11 AM.  That gave me time to drill a hole in each of the two U-bolt retaining plates and cut a short piece of 1″ square aluminum tube to use as a spacer.  That was the last fabricating I needed to do and we got busy staging all of the materials we were going to need to get the tower work done efficiently.

Setting up the tools and parts outside the "drop zone" of the 40-foot tower on the east end of the house.

Linda set out a sheet near the tower but not in the “drop zone.”  We spread out materials and tools on the sheet and used it to make sure we could find things quickly and keep them from getting lost in the grass.  I also brought all of my tool boxes to the tower area.  With everything assembled it was time to climb.  I set up our 7 foot step ladder on the east end of our rear deck to provide access to the roof near the tower.  Mike helped me into his climbing harness and got it adjusted.  Once on the roof I took the harness off temporarily as my first task was to remove the 2m/70cm base station antenna.  After clipping the plastic cable ties I lowered it down to Mike while Linda took photographs.  (She helped with many aspects of the work today but was the only photographer.)

I put the harness back on and Mike tossed me one of the 100 foot ropes which would eventually be used to haul materials and tools up and down the tower.  I secured the haul rope to one of the unused seat clip rings and Mike instructed me on how to secure the harness while climbing.  I put the waist strap around the tower and clipped it in.  I then put one of the two fall cables, attached to the ring at my upper back, around one of the legs above one of the cross bars above my head and clipped it into the ring at my chest.  The tower is adjacent to the east end of the house and is attached to it by two pipe assemblies just below the soffit (the house has hip roofs) so it was easy to step onto it.  After that things got tougher.

The horizontal trussing on the tower is two feet apart vertically.  That spacing was right at the limit of how high I could lift my right foot and required me to pull myself up part way until I could push with my right leg.  Once up on the next rung I attached the other fall cable, moved the first one higher, and slide the waist strap up to position myself for the next step.  I repeated this pattern with the two fall cables and the waist strap as I worked my way slowly up the tower, clipping old plastic cable (zip) ties as I went.  The tower definitely had some give but I was quickly acclimated to the amount of sway and found it to be acceptable so we decided not to guy the tower with the other three ropes, which would have slowed my ascent even more.

When I finally reached the top of the tower I untied the haul rope, looped it over one of the southeast facing horizontal bars and hauled it up allowing the free end to lower down to the ground.  Mike then tied the rope to the standoff pulley I had fabricated and hauled it up to me.  I already had cable ties, a diagonal cutter, and a pair of slip pliers with me.  I set the threaded rod on the northeast and southeast cross bars, inside and against the two legs that were parallel to the side of the house, and secured it with cable ties.  This was a three-handed job that I had to do with two hands but I got it done while only dropping one cable tie.  With the pulley rod secured I undid the rope and then undid the knot tying the two loose ends together.  I fed one end through the pulley and retied it to the other end.  We now had a way to haul materials and tools (in a bucket) up to me at any needed height while keeping it 18 inches away from the tower.

The next task at the top of the tower was to remove the old TV antenna, mast, and rotor.  When I finally had a close up view of these old components it became apparent that my best course of action was to try and unclamp the base of the mast from the rotator, lift it off of the rotator, and toss it to the ground.

The mast clamp parts were all very rusty so Linda got the WD-40 and Mike sent it up in the bucket.  I sprayed the nuts on the mast mounts and also the rotator leg clamps.  I tried undoing the mast clamps with a slip pliers but it was no good, so Mike sent up three open/closed end wrenches.  One of them was the right size and to my surprise the rusted nuts broke loose and started backing off.  One of them did not want to come off but unscrewed the entire bolt instead.  Fine.  The bolt had a screwdriver slot in the top and was threaded into the rotor housing and I did not care how it came out as long as it did.  I got the mast clamps loose enough that I could work the bottom of the mast free from the top of the rotor.  There was a lot of rust there too.  After clipping some coax cables, rotor control wires, and plastic cable clamps I repositioned myself up one rung on the tower so I could get enough leverage to the lift the mast clear of the rotator collar and control it well enough to make sure the antenna fell to the ENE away from the house and my helpers down below.  And that is exactly what happened.

The first antenna to get mounted was the outdoor antenna for the cellular booster system.  Mike sent the antenna up in the bucket along with the various pieces I needed to secure it to the short top/center mast support tube so the entire antenna, which is omnidirectional, was above all parts of the tower.  What would have been an awkward assembly on the ground took on added difficulty 40 feet in the air but I got it secured with good access to the N-female connector on the bottom.

We decided to run the coax on the outside of one of the tower legs rather than down the inside of the tower.  Mike tied the LMR-400 coax to the rope and hauled it up to me.  In addition to the haul rope Mike tied a second control line to the bucket to keep it from swinging all over the place.  I connected the coax to the antenna feed point and then wrapped the connection with coax seal tape.  I then routed the coax down the east leg of the tower and zip tied it to take the weight off of the antenna connection.

Next up was the 2m/70cm amateur radio base station antenna, often referred to as a 2m/440 dual band antenna.  (In this nomenclature the “2m” refers to a range of wavelengths for one of the VHF ham bands and the “440” refers to a range of frequencies for one of the UHF ham radio bands, so it is a mixed units designation.). The antenna is about five feet long with three short counterpoise (ground plane) rods near the base.  It had an LMR-400 style cable connected to it but with PL-259 male connectors on each end.  The antenna feed point is an N-female connector so I had an adapter installed to make everything compatible.  Mike removed the coax and the adapter, zip tied the antenna to the haul cable at three points, put the 10mm wrench in the bucket, and hauled it up to me.

The ham radio antenna was also tricky to get mounted.  I installed it at the top of the northwest leg so that most of the antenna was above the tower and two of the three short counterpoise were parallel to the west (N-S) and northeast (NW-SE) crossbars.  The antenna by itself is light in weight but it is five feet long and mounts at the bottom nine inches, so most if it was above me with a tendency to wave around in mid-air.  With the coax connected, however, it weighed quite a bit more.  I temporarily zip tied the coax to take the weight.  I then had to hold the antenna with its base against the northwest post at my head level, push a U-bolt through the mounting bracket and past the tower leg, slip the mating clamp over the two ends of the U-bolt, and then get a small lock washer and nut on each threaded bolt end.  I then had to repeat this for the second U-bolt.  Again, a three-handed job that I had to do with only two hands.

The bonus to this work at the top of the tower was a commanding view of the surrounding countryside, which was mostly trees in every direction.  I even saw two towers far to the north and was kept company by a soaring vulture just to the NNE.  I was also able to determine that the tops of the large white pine trees behind the east end of our house are about 10 feet higher than the top of our tower, putting their overall height at about 55 feet as their bases are lower than the base of the tower.  We plan to put the 70 foot tower at a spot that is surrounded by these trees on three sides (W, S, and E) so the top of the tower, and any antennas mounted there, will be well above the tree tops.  That is especially important as we plan to eventually put an HF beam antenna up there on a mast attached to a rotator and it will need to be able to rotate freely for 360 degrees.

The final antenna was the hardest.  The Antennas Direct DB8e OTA UHF/digital TV antenna was very large and heavy by comparison to the other two.  In this case ‘heavy’ meant a few pounds.  It is actually two UHF antennas mounted at the end of a dual support arm structure.  The support arm mounts to a vertical pole, such as a tower leg, at its midpoint and there is a combiner box located there as part of the mount.  A short length of RG-59 (75 ohm) coax connects each antenna to the combiner box and the main coax connects there as well.

RG-59 is a different kind of coaxial cable from the LMR-400 used for the first two antennas.  LMR-400 has a 50 ohm characteristic impedance and is used for receiving and transmitting RF energy with considerable power if needed.  RG-59 is much smaller in diameter, more flexible, has a 75 ohm characteristic impedance, and uses F-connectors that are the standard for OTA TV, video, and satellite cables.  But I have gotten ahead of myself.  I had to come down a few feet on the tower to install the TV antenna but before doing that I had to start securing the transmission lines to the tower legs with cable ties.

Mike rigged up the haul rope in a ‘Y’ to lift the antenna from its center of gravity while actually attaching the rope to its ends.  That allowed the haul rope to both support the weight of the antenna and keep it oriented correctly while I positioned and clamped it to the southwest tower leg with the dual support arms pointing in an east-west direction.  Because of where I had the pulley mounted, and the length of the ‘Y’ in the support rope, I had to mount the antenna a few feet lower on the tower.  Fortunately the slightly lower height was not going to affect its performance.

Like the ham radio antenna, the OTA TV antenna mounted to the tower leg at two points.  The upper assembly was a U-bolt with a retaining bracket on the back side.  The lower assembly was a pair of straight bolts that went through the combiner box past the tower leg and had a retaining bracket on the back side.  The antenna came with wing nuts instead of washers and regular nuts, which helped a little, but I really needed three hands to get the antenna into position and tighten the mounting brackets.

Once I had the antenna sufficiently attached to the tower I was able to position the support arm close to the southeast facing side of the tower.  I then pointed the antenna on the east end of the arm ESE towards the Detroit area TV towers and tightened the two nuts on the mounting studs.  (The horizontal dual support arms are about 3 feet long so I was able to reach through the tower to get to the mounting studs and nuts.) I left the antenna on the west end of the support beam loose and turned it out of my way so I could complete other tasks.

Mike attached the end of the main RG-59 coax to the haul rope, put the amplifier and a 2-foot length of RG-59 coax in the bucket along with lots of zip ties, and pulled them up to me.  The amplifier is about 3″ wide by 2″ high and 1.5″ thick including the concave plastic backplate.  The backplate accepts two zip ties for mounting to a pole.  I positioned the amplifier about 8 inches below the antenna combiner box and cinched up the two zip ties.  I then connected the short coax to the combiner box output and put the combiner back it its protective, weather-gasketed plastic box.  I connected the other end of the short coax to the amplifier input and wrapped the connection with coax seal weatherproofing tape.

I attached the main RG-59 coax to the output of the amplifier, which is also the DC power input, and wrapped the connection in coax weather seal tape.  I then dressed the cable and secured it to the tower leg.  I aimed the antenna on the west end of the support arm WNW towards the East Lansing TV towers and tightened the nuts to lock it in position.

At this point I was finally done working on the antennas but had three coaxial transmission line running down the outside of the tower, one by each leg.  As I descended the tower, reversing the protocol I used going up, I secured all three cables every few feet.  I finally had my feet back on the roof at 2:20 PM, almost exactly 2 hours and 30 minutes from when I started climbing.  Projects usually take me twice as long as I think they will but this was about half as long as I thought it would take, so we were all pleased that the work had gone smoothly and relatively quickly.  My main objective was to get the old TV antenna down and the three antennas up but my secondary objective was to only climb and descend the tower once.  Mission accomplished, at least for now.

By now we were all hungry and thirsty so Linda made chickpea salad sandwiches and set out fresh sweet peppers, sliced apples, baby carrots, and cold water.  After a suitable lunch break we returned to the next phase of the work which was routing the coax cables into the cable entry box (CEB) and making the connections.

We started with the RG-59 coax from the OTA TV antenna.  I coiled the extra cable and hung it on the tower (with zip ties, of course), routed it into the CEB and connected it to the power inserter / lightning arrestor.  We purchased this cable from a Radio Shack store in Florida two winters ago to hook up our bus to the RV resort cable TV system.  Besides the coax it had a separate ground wire.  The amplifier and the power inserter both had connections for a separate ground wire so I connected it on both ends.

We had already routed a 75 ohm video cable from our bedroom TV to the sump pump room in the basement.  I selected a suitable length of this same type of cable from our existing inventory, connected it to the other side of the power inserter, and routed it through the back of the CEB into the sump pump room where Linda guided it.  Conveniently, I had a double-ended F-female barrel connector designed to connect together two cables with F-male connectors.  I plugged in the AC power adapter for the power inserter, which was already in the sump pump room, and we went upstairs to see if we were receiving any TV stations.

We set the ‘Source’ on the TV to ‘Antenna’ and did an ‘Auto Scan’ for digital channels only.  There are very few analog TV signals still in use and the ones that are reside in the old VHF TV spectrum which our new antenna cannot even receive.  The scan found 58 signals, which obviously included the sub-channels.  Besides the main Detroit stations and the East Lansing PBS station we got other Lansing area stations and even a station from Flint.  The nice thing about digital TV is that if you get a picture at all it is very good.

There is a large TV tower at I-96 and US-127 on the southeast corner of Lansing so we were probably picking it up.  There are several TV towers SSW of Lansing about 35 miles that serve Battle Creek and may serve Lansing and Kalamazoo.  They are 50+ miles from us and I did not have the west antenna pointed in exactly that direction but it may have been close enough to pick them up.  Flint is at least 35 miles away straight north off the sides of both antennas so theoretically we should not have received any stations from that direction.  We will have to check the AntennaPoint.com website and confirm by station identifier what stations we are actually receiving.

Feeling good about our success so far we routed the coax for the cellular booster across one of the support arms that brace the tower to the house just under the east soffit.  We dropped it down next to the wall and brought it into the bottom of the CEB, replacing the hole plug with a rubber grommet.  Routing it this way kept it out of the way of future foot traffic, or lawn and garden work, in the space around/between the tower and the CEB.  I connected the cable to the lightning arrestor and coaxed it unto position inside the CEB.  LMR-400 is stiff and bending it sharply will damage it.

I connected one end of the 15-foot LMR-400 cable to the other side of the antenna arrestor and routed it into the sump pump room where Linda guided it into position.  I secured it to the ceiling, brought it down the opposite wall, put a large 180 degree bend in it, and attached it to the connector on the bottom of the cellular booster.  I turned it on and watched the lights blink for a while.  All three of us then started checking signal strength throughout both floors of the house.  All five of the ‘Alert’ lights went from blinking yellow, which means the unit is adjusting the gain on that band, to solid yellow, which is not described in the manual.  Since we had not yet registered the device with Verizon Wireless I turned off the booster.

Back out at the CEB I removed one of the hole plugs directly below the input of the Morgan VHF lightning arrestor.  We routed the coax for the 2m/440 ham antenna across the tower brace, down the wall, and around through the bottom of the box where I attached it to the lightning arrestor input.  I had an old piece of 50 ohm coax with an N-male connector on one end and a PL-259 (male) connector on the other end.  I attached the N-connector to the output of the VHF lightning arrestor and fed the other end through one of the 2″ conduits into the sump pump room where Linda routed it out into the ham shack.

We set our “Go Box” on the desk, plugged the PL-259 into the SO-239 socket on the back of the case, plugged it in to AC power, turned on the power supply, and turned on the radio.  The radio, an Icom IC-7000, came up tuned to the South Lyon (K8VJ) repeater.  I transmitted and successfully triggered the repeater, which is currently at a secondary site about 20 miles from our tower.  Mike went out to his car and used his mobile radio to verify that we could transmit to and receive from the repeater.  I had a lot of background static (white noise) so Mike switched modes and transmitted directly to our antenna.  The signal was full scale and full quieting.  I have a ground lug in the Go Box but did not have it connected.  I vaguely recalled that I had to ground the box at the previous house to eliminate a noise issue.  (The radio and power supply are grounded to the box.)

I switched the radio to UHF and it was set for the Novi repeater.  I listened but did not hear anyone transmitting so I transmitted, giving my call sign and a brief message, and then listened.  I did not get a reply even though Mike was also monitoring the Novi repeater so I switched back to the South Lyon repeater.  Mike indicated that I had, indeed, triggered the repeater and that a couple of other hams acknowledged hearing me in addition to him.  It thus appeared that I did not have something set up correctly on the receive side of the radio for the Novi repeater but the system (radio, cables, arrestor, antenna) was clearly working.

That was enough work for one day so we gathered up all of the tools and unused materials and put them away.  We offered to take Mike to dinner as a ‘Thank You’ for his assistance.  It was more than helpful to have someone on the ground who was familiar with tower operations.  We considered several dining options but opted for Olga’s in Brighton.  Linda and I had small salads, sans the Feta cheese, veggie Olga’s that were excellent, and curly fries without Tabasco sauce for the ketchup.  Warning:  As inconceivable as it may sound, Olga’s does not have any kind of hot sauce in its restaurants.  Mike had a dish with chicken in that he said was very good.

Mike headed home from the restaurant as did we.  We were tired but very pleased with what we had accomplished in the course of the day.  We celebrated our accomplishments by watching several programs on Detroit PBS, something we have not been able to do for more than two years.
