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.

 

 

2015/06/29 (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.

 

2015/06/23 (T) Grounded

As I wrote in yesterday’s post we did not turn off the lights last night until almost 1 AM because we were keeping a close eye on the weather moving across the lower portion of Michigan’s Lower Peninsula.  Although strong to severe storms were still forecast from 1 AM to 5 AM they either did materialize at our exact location or we slept through them.  We had the house closed up and the air-conditioning on, so that cut down the sound level of outside noises.

A cold front had pushed through by sun up and we woke to a cool morning with blue skies and noticeably lower humidity.  We did not have any trees, or even big limbs, come down and there was no damage to our brand new roof.  The forecast yesterday was threatening enough, however, that in the morning we took the potted plants, and as much of our outside lawn furniture as we could find room for, inside including our sun umbrella and trash cans.  I planned to be gone most of the day, and Linda was leaving mid-afternoon to go to dinner and a movie with Diane Rauch, so our first chore was to put all the lawn furniture, plants, and other outdoor stuff back outdoors.

This week is mostly being devoted to ham radio with the ARRL Field Day as the crowning event this weekend.  My specific focus for most of the week, however, has been the “communications tower” adjacent to the east wall of our house.  As described in previous posts we installed a cable entry box (CEB), mounted the cellular booster in the basement, mounted the inside cellular antenna, and ran coax cables.  The antennas will (hopefully) be mounted on the existing 40 foot tower tomorrow, cabled into the CEB, and cables run from there to devices inside the house.  With any luck by the end of the day tomorrow we will have decent cellular service inside the whole house, the ability to watch OTA TV programs on two different TV sets, and finally be able to connect one of our radios in the ham shack to an antenna.  Today, however, was planned to mostly address other things.

I had an appointment with our dentist at 10:20 this morning and left at 9 AM.  I planned to stop at Chuck’s bus garage and check that the key he lent me worked, but I needed gas for my car.  I did not have time for both and did not really have a choice; I would have to check the key some other time.  I ordered two cables yesterday from Scott (AC8IL) at Adams Electronics.  Later in the evening I was unsure if I had specified the connectors correctly so I called and left a message.  I called again this morning to make sure the message got through.  It did, and my original connector specifications were correct.

I arrived at the dentist’s office about 10 minutes before my appointment time.  I called Rick Short at Isringhausen USA to make sure he was going to be in before I drove two hours to Galesburg, Michigan after my dentist appointment.  I got his voice mail a left a message.  “ISRI” makes very high tech air suspension driver’s seats that are used as original equipment in motorcoaches, semi-tractors, heavy equipment, and locomotives.  I would really like one for our bus, but it is not proving easy to get.

Dr. Steve and his assistant, Leslie, made molds of my upper and lower teeth and a bite impression.  The molds will be used to make a mouth guard that I can wear while I sleep.  Dr. Steve has a strong suspicion that I am clenching my teeth and the mouth guard will reduce or eliminate the irritation it causes.  I will have to ask if I can wear it during the day too as I am occasionally aware of clenching my teeth while I awake.

I had not heard back from Rick by the end of my appointment so I called the main number at ISRI and talked to the receptionist.  It turned out that Rick was not in today and she transferred me to Jeff Woodworth.  Jeff was willing to meet with me but thought it would be a better use of my time to wait until Rick was available.  My next opportunity to drive to Galesburg will be Thursday and I will likely go as the ISRI seat is holding up our ordering of Flexsteel seats through Coach Supply Direct.

I stopped for coffee and then re-routed for Chuck’s bus garage in Novi.  The key to the garage worked perfectly.  I called Linda to let her know about the change in plans and headed for home.  There is too much to do at the moment to waste much time so I installed the #4 AWG bare copper ground wire I bought yesterday at Lowe’s.  I mounted an offset copper wire lug using the center support stud for the copper back plane in the CEB.  I replaced one of the plastic hole plugs with a rubber plug with a small hole in the center.  The hole I chose in the bottom of the CEB allowed the ground wire to come straight up into the lug.

Another view of the cable entry box on the east end of the house by the 40-foot tower showing the bare copper ground wire that runs to the ground rod and then to one of the tower legs.

Outside the CEB I routed the ground wire around to the existing ground rod and secured it using the new clamp I bought yesterday.  There was an old ground wire connected from a clamp on the tower to the ground rod.  I removed that wire along with some coax and control wires that I had clipped when we removed the old satellite dish.  I then attached the new ground wire to the clamp on the tower.  While we were at it Linda trimmed back a small bush that was growing between the tower legs and I pulled leaves, grass and other stuff out from around the Day Lilies that we transplanted last year around the tower base.

With the CEB grounded we looked at how we might get a video cable up to the TV/monitor in our bedroom.  The wall where the TV is mounted has a hot water baseboard radiator that comes almost to the trim on the door wall.  That end of the radiator has a copper pipe that goes through the floor into the basement and it was easy to locate the pipe in the basement.  I determined that there was enough space behind the pipe to safely drill a hole but I had to drill it from the top side at an angle.  A 5/8″ wood boring drill bit created a hole just big enough for the molded F-connector on the end of the cable to pass through.

We fed the video coax cable above the suspended ceiling in the ham shack area to the location of the hole.  I then fed the cable up from the basement as Linda pulled it up into the bedroom.  We adjusted the amount of cable in the bedroom to allow the wall mounted TV set to move through its entire range of motion.  The other end of the cable was then routed into the sump pump room.

By the time we finished pulling this cable it was 3:30 PM and time for Linda to leave to pick up Diane.  They were headed to Royal Oak for dinner and a movie as the movie they wanted to see was only showing at the Royal Oak Main Theater.

While I was out during the morning Lynch Carpet had called to let us know our Armstrong vinyl tile was available for pickup so after Linda left I closed up the house and went to get it.  The 12 boxes of tiles, container of vinyl adhesive, and container of vinyl grout were all neatly arranged on a small pallet and tightly wrapped in shipping plastic.  Rather than break this down and load each thing individually they used a fork lift to set the pallet in the back of my Honda Element.  The rear suspension settled at least two inches when they transferred the full weight of the pallet to the floor of my car.

When I got back to the house I backed the car up to the garage.  I cut the shipping plastic loose and unloaded the tubs and boxes of tiles.  I put the pallet on the garage floor and then neatly stacked the boxes of tiles on it to keep them off the floor.  Each box contained 14 tiles measuring 16″ by 16″ for a total area of 24.89 square feet.  The Armstrong Alterna tiles are a “luxury vinyl” product, and are about 1/8″ thick.  Even so, the boxes were heavier than I expected so I decided to weigh one.  It tipped the scale at just under 42 pounds.  That meant the entire pallet weighed close to 500 pounds, and, ignoring the weight of the cardboard box, that is about 3 pounds per tile.

When I drew out the design I determined that I would need 158 tiles, some of which would be partial.  Figuring conservatively at 150 full tiles equivalent, and ignoring the weight of the underlayment, adhesive, and grout, the floor tiles will weigh about 450 pounds.  I have no idea what the carpet and ceramic tile that I have removed weighed but the tiles were heavy.  I also have no idea what the furniture weighed that we have removed but also have no idea what the new furniture will weigh.  The intent was that the new floor and furniture would weigh less than old stuff but we will see.

I traded phone calls with my dad and we finally got to talk for a half hour starting at 4:30 PM.  He turned 90 this past Sunday.  Mike Fearer from Bid-Rite Concrete called at 6 PM and arrived about 10 minutes later to discuss the foundation for our 70 foot ham radio tower.  I had printed off a page from the Universal Tower website showing their tower base.  I also downloaded and printed their base and tower installation instructions.  I had a set of these to give to Mike so he would have some idea of what the project is about.  We looked at the proposed location for the tower and access for his dump cart.  We also talked about the base, a rebar cage, a form around the top of the hole to allow the concrete to be slightly above ground, and a jig to make sure the base is level and the tower is plumb.

He said he was interested in the job and would work with me and Phil Jarrell (the excavator) to get it done.  Rather than bid the job he would just do it for time and materials.  He also said the current price of concrete was about $100 per cubic yard.  We will need about six (6) cubic yards to fill the required 5′ x 5′ x 6′ (deep) hole.  He thought he might be available the middle of next week but I don’t think I could have everything pulled together that quickly.

After Mike left I went to Lowe’s and picked up five 40 pound bags of topsoil, a 1-in/2-out signal splitter (rated for 5 MHz to 2.4 GHz), and a plastic snap cover channel for hiding the video cable we ran up into the bedroom from the basement for the TV set.  I then went to the Meijer’s supermarket just across Grand River Avenue for soy creamer but they did not have what I was looking for.  As long as I was there I had a salad for dinner at the in-store Subway.

While I was sitting there I called Mike Sharpe (W8XH) to confirm that he was available tomorrow to help with the antenna installations on our 40 foot tower.  I mentioned that the only thing I lacked was a standoff with a pulley at the end of it for hoisting stuff up to me.  He suggested that something like that was essential and I agreed, so I headed back to Lowe’s to see what I could figure out.  What I ended up with was a three foot long 7/16-14 threaded rod, a pulley that had a closed eyelet on top (and was big enough for the 3/8ths rope I bought), some 7/16ths washers, and some 7/16-14 nuts.

When I got back to the house I unloaded the topsoil near the part of the east yard that needs to be filled in, took the other stuff inside, and then assembled the threaded rod pulley system.  I secured the pulley on one end of the rod using two of the nuts, one on either side of the eyelet.  I threaded a nut onto the other end, put on two washers, two nuts, two more washers, and another nut.  I ran the first two nuts, with two washers between them, part way down the rod.  I left the second pair of nuts, with washers between them, near the end of the rod.

I took the assembly out to the tower and adjusted the position and spacing of the two pairs of nuts and washers so they would bracket two of the horizontal tower members.  In use I will secure the rod to the tower at each pair of nuts/washers using plastic cable ties.  This arrangement will put the pulley at least 18″ from the tower which should be far enough out that we can hoist the DB8e OTA TV antenna to the top of the tower without it banging into the tower or hanging up on something.  This antenna is the largest thing we need to hoist up. The old TV antenna is considerably larger and heavier, but it is coming down via gravity.

There was a message on our answering machine from Linda’s sister, Sr. Marilyn, who lives in St. Louis.  She was listening to the news earlier today about the storms that went through our part of Michigan and wanted to make sure we were all OK.  By the time we finished talking it was dark and I was done working for the day.  Linda called shortly thereafter to let me know she was on her way home and I mentioned the call with Marilyn.

I finally opened the box with the vertical omnidirectional outside antenna for the cellular booster system and discovered that I should have opened it sooner.  The mounting bracket was designed to be mounted to a vertical surface, such as the side of a house, not a tube, such as a tower leg.  I did not want to postpone tomorrow’s tower work so I will have to get up early and figure out a way to adapt the existing bracket so I can mount the antenna to the top of the tower.

My initial thought was that an aluminum U-channel of the correct size might solve the problem very nicely.  I could drill two holes in the bottom of the “U” to match the two holes in the bracket.  I could then drill three pairs of holes through the sides of the channel.  The antenna would be bolted to the bottom of the channel.  With the open part of the channel held against a vertical tube I could secure it with three long plastic cable (zip) ties.  Conceptually it should work and be easy to fabricate, but will take time which I won’t have a lot of in the morning.  We have to get the two coax cables from Scotty (AC8IL), drop off my car at Brighton Honda for its 100,000 mile service, and be back in time to have the mount fabricated and all of the antennas and tools ready to go by 10:30 AM when Mike shows up.

Linda got home at 9:45 PM, earlier than she thought she would when she left.  She and Diane ate at Luigi’s and had a very nice meal.  They also enjoyed the movie.  We had a big day on tap for tomorrow and we asleep by 10:30 PM.

 

2015/06/22 (M) Cable Me This

We turned the air-conditioning off last night and enjoyed the fresh air, pleasant temperature, and lower humidity.  The overnight low was 58 which made for good sleeping.  We awoke to blue skies and what we thought would be a picture perfect Michigan summer day until Linda checked the morning news (iPad).  There was a story about a storm that moved through the upper plains yesterday and had a bead on Michigan for later today and this evening.  What had been a 10% chance of rain for today had been replaced by a forecast for strong-to-severe thunderstorms with the possibility of strong winds, large hail, and tornadoes.  Ahhhh, summer in Michigan.

Not ones to sit around and wait for the apocalypse we did what any sensible couple would do, I made coffee while Linda reheated the last of the Baked French Toast from yesterday’s brunch.  We had breakfast and then sat on the deck enjoying our coffee and contemplating the end of the world, or at least the possible destruction of our brand new roof.  But it’s insured, so “no worries, maan” as they say in Jamaica.  More coffee please.

We have a whole house generator that runs on natural gas so as long as a storm doesn’t damage it we can survive for a very long time without electric utility power.  Losing our AT&T Internet connection, however, would be a genuine hardship as that would require us to use our Verizon Mi-Fi (without the benefit of the new Fusion5s cellular booster which I plan to install on Wednesday) or go to Panera, McDonalds, or one of the libraries to get online.

Keith showed up around 10 AM to cut the grass.  We were hoping he would make it as we have not had too much rain this past week and the last few days in particular have been dry.  I think this is the first time this season he has been able to cut our grass without it being wet.  It looked nice when he was done.

I got a call from Phil Jarrell.  He had been successful in reaching Mike Fearer of Bid Rite Concrete on Mike’s cell phone.  Based on Phil’s description Mike was interested in looking at our tower foundation project and was expecting me to call so I did, using my cell phone, and this time I was able to reach him.  It turned out that the information about his business on the Internet is out of date.  He is no longer in Whitmore Lake but now operates from near M-59 and Latson Road, not far from us.  We agreed that he would stop by tomorrow at the end of the work day to look at our project.

I did not want to do a lot of heavy work today, as I was still a bit tired and sore, but I needed to mount two lightning arrestors in the cable entry box and mount the cellular booster in the sump pump room so I could figure out what coax cable lengths I needed and go get them from Scott Adams (AC8IL) at Adams Electronics in Wixom.  But first I called Mike (W8XH) to let him know I was planning on Wednesday for the tower work, assuming he was still available and the tower was still standing.

I determined that I needed two coaxial cables and ordered them from Scott by phone rather than take the time today to drive to his place of business.  They will both be LMR-400 with N-connectors on both ends.  One will be 50 feet long, for our 2m/70cm Diamond X50-N VHF/UHF base station antenna, and the other will be 15 feet long, to get from the cellular booster lightning arrestor in the cable entry box to the repeater (amplifier) in the sump pump room.  I will pick them up early Wednesday morning and install them.

One of the lightning arrestors was for the SureCall Fusion5s cellular booster system.  It has N-connectors on both ends, one of which is intended for bulkhead mounting.  It came with an angle bracket that fit over the bulkhead end and I used that to mount it.  I used the 2′ length of LMR-400 that came with the booster installation kit to position the lightning arrestor so the cable from the repeater could exit one of the 2″ conduits and bend around and connect to it.  LMR-400 is a low loss, 50 ohm impedance, coaxial cable that can handle high RF transmit power.  The cellular booster only has a 1 Watt transmitter but is operating at frequencies where energy losses in coax cables become significant.  To do what it does LMR-400 is just under 1/2″ in diameter.  It is fairly stiff and does not make sharp bends so cable runs and connections have to be carefully planned.

The other lightning arrestor was for the Antennas Direct DB8e OTA TV antenna and serves a dual purpose as the power insertion device for the tower mounted amplifier.  The coax cable for OTA TV signals is typically 75 ohm impedance RG-6 with F-connectors.  It is half the diameter of LMR-400 and much more flexible.  It is also typically used to receive low power signals and convey them in one direction; from the antenna to the TV.  Because we are 25 miles from the nearest TV tower and some of the towers are 50+ miles away, I ordered a signal amplifier to go with the antenna.

Ideally you want to amplify an OTA TV signal as soon as it comes out of the antenna and this amplifier does just that.  It will mount on the same tower leg as the antenna about two feet below the antenna feed point.  However, being an active electronic device it needs electrical power to operate.  There are two basic ways that could be done.

One way would be to have power wires, such as +5 VDC and DC Ground that are separate from the coaxial cable that carries the radio frequency (RF) energy.  The two OTA TV antennas on our bus are set up this way with three wires to supply power and control the enclosed rotor.

The other way is to provide DC power through the coaxial cable itself, which is how this amplifier is set up.  The nice thing about this arrangement is that the amplifier only has two connections and they are both coax connectors that can be weather sealed.  To get the DC power into the coax cable, however, requires a special device called a power inserter.  The power inserter, in turn, requires the coax to be split into two segments so there end up being four connections instead of two.  The power inserter for this amplifier very conveniently acts as a lightning arrestor as well, which is why I mounted it to the copper back plane in the cable entrance box.

By boosting what I presume will be weak signals from distant towers the amplified signal should be strong enough to survive the trip through the coax cable to the power inserter, from there to a 1-in/2-out signal splitter, and then through additional lengths of coax to the two TV sets.

After getting the two lightning arrestors mounted in the cable entry box I took a break for lunch and then went to Lowe’s for some supplies.  When I got back home I turned my attention to mounting the SureCall Fusion5s cellular booster (repeater amplifier) in the sump pump room.  The sump pump is in the northeast corner of the basement, which is also the northeast corner of our ham shack and office.  (The ham shack occupies the north wall and my desks occupy the east wall.  Most of the rest of the room is storage.)

I gutted and rebuilt this space, with the help of long-time friend John Rauch, before we moved in and created the large closet (small room) around the sump with insulated walls to contain sounds.  I installed an electrical sub-panel in this room to provide power to the office and ham shack desks and to an RV outlet by the pull-through driveway.  I fed the power for the RV outlet through the bond on the east wall just above the concrete block foundation and ran it underground to the far side of the driveway.  It was my intention from the beginning to mount a cable entrance box next to the power feed and have all of the coax cables and control wires for outside devices enter the sump pump room in the same manner as the power.

The ham shack/office walls are finished with T-111 exterior plywood with 4″ groove spacing and I finished the interior of the closet the same way as I knew I would eventually want to mount things to the walls.  I mounted the SureCall Fusion5s booster on the west wall of the closet about a foot inside the door and just below my eye level so I could see all of the connectors, switches, and indicator lights on the top and front of the unit.  It had four mounting tabs, two top and two bottom, that attached easily to the wall with short wood screws.

There is a duplex AC electrical outlet on that wall and one on the opposite (east) wall.  The power supplies for the cellular booster and OTA TV antennas will plug in to these along with the sump pump and the charger/controller for the battery powered backup sump pump.  One of the things I bought at Lowe’s were two outlet expanders which I installed in these two duplex outlets.  I also bought a switch with a pilot light to replace a single pole Decora switch that will eventually control the light in the closet.  I installed the switch but did not complete the wiring as I have to tie it in to the light fixture which requires me to cut the power to that circuit.   I would also like to replace the bare bulb fixture while I am at it but have not yet purchased a replacement.

Although it was late afternoon I decided to install the inside antenna for the cellular booster system and run the coaxial cable that connects it to the booster.  The antenna is designed to mount to a flat ceiling and provide a hemispherical coverage area below the plane of the ceiling.  I had previously figured out that if I mounted this antenna in the main floor hallway near the midpoint of the house I could connect it to the cellular amplifier using a 50 foot length of coax cable that came with the system.

The desired mounting location was opposite the door to the hall closet and the access to the attic is through the ceiling of that closet, so that was very convenient.  We emptied the closet, removed the clothes rod, and setup our six foot step ladder.  I removed the piece of foam insulation we currently use to seal the attic access opening and climbed up, flashlight in hand to check out what was on the other side of the ceiling.

Our desired location for the antenna was free of problems on the back side so I drilled a 3/4″ hole for the mounting stud and used a piece of rebar to poke a hole through the insulation for the coax cable that came out of the stud.  Linda fed the coax and stud through the hole and I put the retaining nut on the stud from the attic side of the ceiling.  The antenna is shaped like a coffee filter, is about six inches in diameter at the ceiling, and tapers down to about four inches in diameter about four inches from the ceiling.  The housing is white plastic and blends in well with the ceiling paint.

About four feet from where we installed the antenna is a chase that runs from the attic to the furnace room in the basement.  It appears that once upon a time something having to do with the furnace ran through this chase, such as the combustion air intake.  The combustion air is now drawn through the back wall under the deck and the exhaust goes out through the east wall of the basement via a double wall stainless steel flue pipe.  The chase is no longer used for furnace or other utilities although there are electrical cables to switches mounted in the bathroom walls and it still contained a piece of 4″ plastic pipe.

I positioned myself near the chase and guided one end of a 50 foot length of LMR-400 coax down through the pipe and through the hole into the furnace room while Linda held the roll of coax near the top of the ladder and unrolled it.  At one point the coax bunched up and Linda had to go to the furnace room and untangle it.  At another point the 4″ plastic pipe slipped through the bottom hole into the furnace room which caught me by surprise.  Once the cable was mostly fed through I routed it to the location of the antenna, connected it to the pigtail coax from the antenna, wrapped the connection in weather seal tape to keep moisture out, and secured it with a cable tie.

With the antenna installed Linda started preparing dinner while I dealt with the 37 feet of coax in the furnace room.  The furnace room does not have a finished ceiling so I had access to the areas above the suspended ceilings in all of the adjacent rooms.  In particular I was able to feed the free end of the coax above the ceiling in the office and into the sump pump room.  I secured the cable with plastic cable ties at two points in the furnace room to keep it away from the flue and various hot water pipes.  I had about 8 extra feet of cable so I made a large coil with two loops such that the free end came off the loop straight down into the connector on top of the booster.  I hung the coil on the wall above and to the right of the booster making for a very neat installation.

I took a shower to try and get rid of some of the fiberglass itch while Linda finished the dish she was making for dinner.  It was a complex Indian style dish with Basmati rice, garbanzo beans, Swiss chard, onions, and shallots, seasoned with salt, black pepper, cayenne pepper, cumin seeds, garam masala, fresh lemon (zest and juice), and fresh dill that Linda grew herself.  The house was filled with the aromas of all these ingredients for a couple of hours as they were prepared and combined into the final dish.  It tasted as good as it smelled with many flavor layers.

Our beautiful blue sky gave way to high, thin clouds through the morning and then to lower, thicker clouds during the early afternoon.  By 2 PM the clouds to the west were dark as I drove to Lowe’s in Howell and the first, heavy rains came as I got to the parking lot.  I waited a few minutes and they stopped so I got into the store without getting wet.  I had the same good fortune on my way back to the car.  The sustained rains came later in the evening along with a tornado watch.  We went to bed before 10 AM but did not go to sleep.  It took me a long time to write this post and we kept a watchful eye on the weather radar.  Although thunderstorms were forecast as a certainty from 1 to 5 AM with the possibility that they might be severe, we finally turned the lights out around 12:45 AM and tried to get some sleep.

 

2014/07/03 (R) First Overnight Visit

I awoke this morning to the sound of light rain which had started sometime during the overnight.  The landscapers were supposed to be back first thing this morning to continue working on the retaining walls in the back, but the rain had made the work site muddy enough that I figured they would not be here today, which turned out to be the case.  The clouds cleared off by mid-morning and by early afternoon the site had dried out enough that they could have continued with the hand work.  With tomorrow being a holiday, however, I did not expect them to begin their workday at 1 PM.

After we had breakfast I left around 10 AM to drive to Adams Distributing in Novi to return a pair of battery chargers.  I visited with Scotty (AC8IL) for a while discussing his ham radio setup.  Since getting back into the hobby after many years he has done very well making DX (long distance) contacts all over the world.

I got back around 11:30 AM and our son and grand-daughter showed up shortly thereafter.  Today was Brendan and Shawna’s third wedding anniversary and we all agreed it was an opportune time for Madeline to have her first sleepover at our house, allowing her parents some much needed adult only time.  Brendan brought the porta-crib and portable stroller, and transferred the car seat to Linda’s car.  Brendan visited until it was time for Madeline’s nap and left once she was asleep.

Madeline had a good long nap and woke up refreshed and ready to go.  And go she did; we played with toys, read books, explored the main floor of the house, and went for an explore in the yard.  We have a five acre parcel, so it was an extended exploration.

For dinner, Linda cooked some Dr. Praeger’s vegan burgers and served them with sliced parsnips with sautéed in a small amount of water and quinoa with dried cranberries.  Madeline enjoyed all of it, along with some peas and strawberries.  I have not had parsnips very many times in my life.  When sautéed they taste like slightly peppery cooked carrots, which tend to be sweet.

We had more play time after dinner until 7:30 PM when Linda got her ready for bed and she had her evening bottle.  She was tucked in her porta-crib at 7:45 PM and quickly drifted gently off to sleep.  Brendan also brought their baby monitor and set it up, so we were able to keep an eye on her without opening the door to the bedroom and possibly disturbing her.

We stayed up a little while longer and then turned in around 9:30 PM to watch another episode of Doc Martin.  At 10:12 PM we lost power for a few seconds and a minute later it happened again.  We received a couple of e-mail notifications from our standby generator regarding the loss of utility power but never got one indicating that the generator had started.  Apparently the outages were too short to trigger the start sequence.

Even though most of the critical electronics in the house are connected to uninterruptible power supplies, I got up and shut down all of the computers, NAS units, and the laser printer.  The power flickered a couple more times but we never lost our Internet and were able to watch the last 10 minutes of Doc Martin.  Our last message from the generator indicated that it would stop notifying us of the situation until the fault had cleared for 24 hours.  The generator ran a successful self test at noon today, as it does every Thursday, so I was confident that it would start if needed.  We had a power outage while we were away this past winter during which the generator started and the automatic transfer switch transferred the house to the generator, so I was also confident that all if this would work if needed.

The worst part of this kind of momentary power outage is that the UPS units all start beeping (an alarm) as soon as they lose AC power.  It’s kind of like a smoke detector or other alarm going off; it tends to jolt you awake and once up it is hard to go back to sleep as you lie there anticipating the next alarm.

 

20140605 (R) Apple Roku

Linda had to go into the bakery today which left me to catch up on phone calls and errands.  I made more phone calls to contractors this morning and had better luck than yesterday reaching people or at least leaving messages.  I rescheduled with Gary from GM Construction to come discuss the pole barn project.  I also got hold of Bratcher Electric and determined that the annual maintenance on the whole house generator could wait until we are ready to do the conversion from propane to natural gas, which they can handle.  In talking to Mike Bratcher I also determined that we can install a main panel in the garage just after the transfer switch and then run power directly from there to the pole barn rather than from the main panel in the basement.  While we are at it, we could redo the sub-panel in the garage, feeding it directly from the new main panel rather than the main panel in the basement.  The basement panel is very crowded and we have wires carrying electricity back and forth unnecessarily.

I got a call from Butch with an update on the negotiations of the sale of the major portion of their business assets.  Linda has been advising them relative to valuation, accounting, and tax issues and we have been helping them with purchase agreement language.  It looks like they are in the final stages leading up to a closing of the deal.  Their big annual event is coming up in early July and they will likely be busy with the transfer of inventory and training of the buyer during and after that event.  I need to get our bus down to their place to work on some projects and help Butch work on getting their bus conversion done enough that they can live in it this winter in the southwest.  Based on things going on at both ends, it looks like the window for that work will be mid-September to sometime in November, weather permitting.

Our converted coach friends, Pat and Vickie, have some older Motorola GMRS handheld radios that they like but the charger bases have disappeared.  My ham radio friend Scott (AC8IL) is in the commercial mobile communications business so I checked with him to see if chargers were still available.  They were and he had a couple of the drop-in style charger/bases in stock!  Scotty is just that kind of guy.  I picked them up this morning and will deliver them to Pat and Vickie at the GLAMARAMA rally.

Apple Roku sounds like an interesting dessert, but it’s not.  It might be an either/or situation, but it could be a both/and.  John Dewey was a both/and kind of guy, so I favor that approach.  We were intrigued by Steve and Karen’s Roku Internet TV streaming device last night so I stopped at Best Buy today on my way home from running my errand to see if they had them in stock and if so at what price.  Not only did they have them, they had three different models.  The “stick” was $50, the Roku 2 was $70, and the Roku 3 was $100.  (The Roku 3 does not have A/V connectors like the Roku 2, only HDMI, but it has a five times faster processor.)  But that was not all, oh no.  They also had the Apple TV device for $100 and two other similar products, one of which looked like an Amazon/Kindle thing and the other one a WD thing, whatever that is.

The Roku units (2 and 3) have access to a lot of content on a free, subscription, and pay-per-view basis.  The Apple TV unit has access to content on the same basis but the selection may not be as extensive; it’s hard to say for sure as the devices are not easy to compare directly.  The Apple TV unit, however, has one huge, unique feature; it can mirror anything on an iOS device, such as our iPads, to a TV/monitor.  The iPad can also be used as a control panel for the Apple TV device.

We do not have to choose between a Roku and an Apple TV unit, of course, we can get and use both if we want; it’s just a matter of money.  Between the two TVs in the house and the two in the bus it could be a lot of money if we wanted dedicated units of both types on all four TV/monitors.  We always have the option of moving things back and forth, but in general I prefer not to do that.  To the extent we can afford it I prefer to have the house and the bus set up so that the only things we move between them are the things we have to, such as ourselves, our food, our laundry, our computers, our cats, and some of our ham radio gear (at least for now).  The best solution, however, may be to get one of each device and move them around as needed.  That would give us the best cost/benefit ratio, but not the most convenience.

When Linda got home from her day at the bakery we finished the Egri Merlot we had opened the other night and caught up on the day’s events.  We decided to try the Apple TV device first and see how it worked in our situation.  Linda made an onion, mushroom, tomato Ragu, and served it over the leftover power grains.  It was very tasty.  After dinner I went to Best Buy to get the Apple TV device while Linda prepared fresh strawberries for dessert.  Fresh strawberries are a favorite treat of ours.  She served them with small pieces of Dandelion Small Batch Chocolate made from 70% Ambanja Madagascar 2013 Harvest beans.  The chocolate was excellent and unique.  It was a thank you gift from our son and daughter-in-law for Linda’s babysitting services while they were in San Francisco, California.

We connected the Apple TV box to one of our HD TV/monitors and went through the setup procedure.  We decided to test it on some PBS content, which required us to set up an account with PBS and enter a validation code that the Apple TV box provided.  We also downloaded an app onto Linda’s iPad2 that allowed it to mirror whatever was on its screen to the Apple TV.

We used the mirroring feature to watch Season 1, Episode 5 of Doc Martin, but it proved to be unusable.  The image was fine on the iPad2 but the Apple TV could not keep up.  I found that to be odd as our home WiFi network should have more than enough bandwidth to deliver the data stream between the devices, but maybe not.  I presumed that the limiting factor in our network was the data rate coming into our DSL gateway from our AT&T landline, but that was obviously fast enough to deliver the content from the gateway to the iPad without buffering hesitation.

We turned off the mirroring and finished watching the episode on the iPad.  Still, the content delivered directly from the gateway to the Apple TV looked great, and the mirroring will be useful for showing photos and anything else on our iPads.  We may reconfigure the Apple TV to use one of our other wireless networks and see if that helps.
