2015/11/03 (T) The Penultimate Cut

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

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

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

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

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

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

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

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

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

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

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

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

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

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

 

2015/07/06 (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.

 

2015/07/02 (R) 100,000 Radios

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

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

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

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

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

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

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

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

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

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

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

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

 

 

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

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

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

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

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

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

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

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