2015/07/06 (M) Arrested

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.

2015/06/29 (M) Website On The Air

Linda was up at 5:55 AM this morning and left for the bakery at 6:15.  Experience has shown that this is usually early enough to get ahead of the morning rush hour traffic inbound to the Detroit metro area from the northwest.

I got up about an hour later, had granola for breakfast, and enjoyed my morning coffee (Sweet Seattle Dreams half-caff blend from Teeko’s) and then made a run to Lowe’s to purchase a couple of copper ground lugs and 5 feet of #10 green ground wire.  Back home I tried to use one of the ground lugs to terminate the ground wire from the cable entry box (CEB) to the 36″ ground bar on the wall behind the ham radio desks but it’s shape prevented the wing nut from going onto the stud.

I planned to use the other lug to attach one end of the #10 wire to the ground bar and put a male spade lug on the other end to mate with the connector on the Go Box ground pigtail, but that clearly was not going to work.  I dressed the ground wire and (temporary) coax in the ham shack and put the ceiling tile back in place.  I then started cleaning up the living room and small bedroom per Linda’s request before she left this morning.  Some of our (my) projects have a way of expanding throughout the whole house.  I had hoped to also pick up the coax cables spread out in the recreation room, and at least start to straighten up the ham shack/office, putting materials away and moving tools to the garage.

At 10 AM I made a few phone calls.  The first was to Rick Short at ISRI USA regarding the 6860 bus driver’s seat and a possible visit tomorrow morning.  I got his voice mail (again) and never got a return call (again) so I gave up on getting any assistance from him or from ISRI USA.  I called Linda to make sure she did not have any commitments on Wednesday and then called Josh at Coach Supply Direct to set up a visit to his shop for Wednesday late morning.  Linda and I plan to finalize our Flexsteel furniture order and give Josh the deposit during that visit.  Next I called Scott Adams, AC8IL, at Adams Electronics and ordered a 20 foot length of LMR-400 with an N-male connector on one end and a PL-259 connector on the other end.  Scotty and I also chatted briefly about tower bases.

I e-mailed Scott Neader at QST.com regarding the transfer of the SLAARC domain name and website from GoDaddy to QST.com and got a reply back right away with an outline of the steps I needed to follow.  First on the list was creating an account for our ham radio club through his billing system.  I took care of that and e-mailed him back.

Keith Kish, from Kish Lawn, care showed up around 11 AM to cut the grass.  When he was done I headed back to Lowe’s to look for an alternate ground clamp and pulley support for the tower but did not find anything suitable.  So as not to have it be a wasted trip I bought three more bags of broken brick pieces to use around the tower base and cable entry box.

I spent some time looking at the Yaesu FTM-400DR/DE on several different ham radio equipment vendor websites.  Yaesu is offering a $100 rebate on this 2m/440 mobile radio through tomorrow.  All of the distributors are selling it for the same price, $599.95 and the rebate brings it down to $499.95, so if I buy one it will come down to who has them in stock and is offering free shipping.

Linda got home from the bakery around 3 PM, earlier than I expected and nice for her.  She went for a walk while I continued to fuss with ham radio and website stuff.

For dinner Linda made a white beans and mustard greens dish.  We eat a lot of lettuce, kale, and spinach, both raw and cooked into dishes, but only occasionally have collard greens or mustard greens.  Mustard greens have a very strong, bitter flavor and I liked them more than Linda did.  I think they are an acquired taste and may be more suitable as an accent ingredient rather than a main one.

After dinner I checked my e-mail and had a reply from Scott at QTH.com.  The QTH SLAARC account invoice was ready so I paid it using a personal credit card.  I then moved the coax from our Icom IC-7000 to Mike’s Icom IC-2820H and turned it on.  Mike was on the South Lyon repeater discussing the Field Day event with Steve (N8AR) and Bruce (W8RA).  Paul (N8BHT) was able to join the conversation but I was not successful breaking in so I just listened.  It was an indication that my power into the repeater was probably still marginal but a good reminder that ham radio conversations are very public.

When they were done I called for Mike and he came back.  We had a good QSO (chat) about the Yaesu FTM-400.  Jim (N8KUE) joined in for a while.  After Jim dropped off we tested my ability to transmit to, and receive from, both the South Lyon 2m and Novi 70cm repeaters.  The added power of the IC-2820H over my IC-7000 (50W vs 35W in the 70cm band) combined with the lower signal loss of the better coax made just enough difference that I could hold the Novi repeater when transmitting although my signal was still on top of a lot of noise coming back out of the repeater.

Linda wanted to watch an episode of Scorpion, followed by NCIS Los Angeles, after which I caught an episode of Two and a Half Men and then turned off the TV.  I will have to make a decision about the Yaesu FTM-400 in the morning.

 

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.

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

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.

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.

 

2015/06/24 (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.

 

2014/09/07 (N) Findlay Hamfest

I set alarms on my phone and iPad last night to make sure I got up at 5:00 AM.  My natural tendency is to stay up a little later each night, something I am now able to do as I do not usually have to get up by any certain time in the morning.  Usually.  Today, however, was the annual Hamfest put on by the Findlay, Ohio Amateur Radio Club and I needed to be at Mike’s (W8XH) QTH in time for a 6 AM departure.  We picked up Steve (N8AR) at the Park-n-Ride lot at Lee Road and US-23 around 6:15 AM and drove non-stop to Findlay, Ohio, arriving at the county fairground at 8:15 AM.  We had a good chat on the way down, which is as much of a reason for going as the bargain hunting once we got there.  I have included a couple of photos in this post.  For more photos, visit:

We each paid our $7 admission fee and got our ticket with a tear-off stub for the hourly and grand prize drawings.  We got parked and set our Kenwood TH-F6 handheld radios to 146.475 MHz (simplex).  We filled out our raffle ticket stubs, dropped them off, and started working our way up and down the rows of outside tables.  The outside sales area was essentially a flea market, sometimes referred to as “trunk sales” because people back their cars up to the road and sell stuff from their trunks.  The spots are cheaper to rent for the day, but you take a chance that the weather will be nice.

We worked the flea market first while the temperatures were cool and the sun wasn’t overhead but also because almost everything offered for sale was used equipment at negotiable prices.  These are often one-of-kind items and the bargains tend to disappear quickly.  By mid-morning I had purchased a good sized NEMA enclosure (steel box with weather tight gasketed door) and a Harris 22.2 telephone butt handset (tester).  I plan to use the NEMA box to create a cable entrance box with lightning protection for RF transmission lines, AC power lines, and control lines.  I got the telephone test set because it will allow me to hook up to the phone line the same way the AT&T technicians do, and because it is not the sort of thing most folks have in their home.

Bruce (W8RA) gave a short shopping list to Steve (N8AR) yesterday at breakfast.  Mike (W8XH) spotted a matched three-piece set of vintage Heathkit gear, one piece of which was on Bruce’s list.  Steve looked at it and they got Bruce on the phone.  Apparently it was close enough to what Bruce wanted that Steve bought the whole set for him as the seller was not willing to sell them separately.

We then moved to the inside vendors, most of whom were selling new merchandise at fixed prices.  There was some used equipment, however, and I bought an Icom CI-V interface set.  This device will allow me to interface our Icom IC-7000 and/or IC-706 to, and control them from, a computer using something like Ham Radio Deluxe (HRD) software.

I also got to meet and talk to Norm, from Norm’s Fabrication in Adrian, and his wife, who is president of the Adrian Amateur Radio Club.  Norm is a welder, and his side business is fabricating tower parts out of steel and aluminum for fellow hams.  If I cannot get what I need from Heights Tower Systems, Norm may hold the key to getting our used tower erected.

A number of other hams from the South Lyon, Novi, Livingston, and SEMDXA radio clubs were there.  I brought my camera and tried to get photos of our club members for the club website.  None of us won anything from the hourly drawings (must be present to win) and we left shortly after noon to meet up at the local Steak-n-Shake for lunch.  I had not eaten breakfast so I enjoyed my garden salad and French fries.  I had a good chat with Dave (K8ESQ), the current president of SEMDXA, and Don (N8CAK) from SLAARC.

We had a good chat on the drive back, stopping briefly at the Michigan Welcome Center on US-23 northbound shortly after entering Michigan from Ohio.  We dropped Steve off at the Lee Road Park-n-Ride and helped him unload the Heathkit equipment.  When we got back to Mike’s I moved my purchases and personal gear to my car and then spent some time examining his Heights tower, especially the fold-over mount.  After studying the parts and the geometry of the design I had a much better understanding of how it works and what we need to get our tower erected and fully operational.

On the way back to my house I got a call from Darryll letting me know he would be out in the morning as long as someone would be home.  Back home I unloaded everything and moved Linda’s car to the side parking pad to make space for Darryll’s truck in the morning.  It was nice to have a day away from our house and property projects.

I spent a little time checking e-mail and websites and off-loading digital photos until Linda called me to dinner.  We had leftover kale salad, quinoa with pineapple and nuts, fresh steamed broccoli, and corn-on-the-cob.  After dinner I recorded the events of the last few days in rough drafts of separate blog posts.  By 10:15 PM the early start and long day finally caught up with me and I turned the lights out and drifted off to sleep.
