2015/07/29 (W) Drive Shaft

I had had a 9:30 AM appointment at Brighton Honda to have a drive shaft replaced and suggested that we just continue on to the Brighton Panera a half mile down the road for bagels and coffee.  Linda never refuses to go to Panera so that is what we did.  The Wi-Fi was out of service but we both bought things to read so we did not care.  We sat in the two comfy armchairs by the fireplace, which was turned on, because the temperature inside was very cool, a frequent problem with this particular Panera store.  We each had a bagel and many refills of our coffee cups and stayed long enough that Brighton Honda called to let me know my car was ready to be picked up.  We left at 12:30 PM and Linda dropped me off to retrieve the ca.

Back home we had the leftover couscous with caramelized onions and the rest of the kiwis for lunch.  Linda finalized her grocery list and headed off in search of food.  I spent the rest of the day and most of the evening working on the design/drawings for the built-in sofa.

Through the course of the day I had QSOs with Jim (N8KUE) on the Novi 440 repeater and with Chris (K8VJ), Steve (N8AR), and Mike (W8XH) on the South Lyon 2m repeater. I also installed an updated driver for the NVIDIA GPU in my ASUS laptop, installed updates on the older Sony VAIO workstation (which still has Windows XP Pro), installed updates on the Linux box, and took time out for dinner (a delicious red lentil potato curry) and dessert (very sweet watermelon).

I went back to work in my office and sent an e-mail to Mike (W8XH) concerning Windows 10.  He replied via the South Lyon 2m repeater.  We had a long chat from 10:10 PM to just after 11 PM that was joined briefly by Steve (N8AR).  There was also a group QSO taking place on the Novi 440 repeater that I listened to in the background.  After I turned the radio off and came upstairs Linda said it appeared that my ham radio transmissions were interfering with our OTA TV signals.  The antennas are on the same tower but the OTA TV antenna is mounted below the Diamond X-50N 2m/70cm vertical ham antenna so I was a little surprised that it would be causing interference.  The vertical antenna has an omnidirectional radiation pattern which resembles a donut sitting on a horizontal surface, so the location directly under the base of the antenna should be a region with very little signal.  Apparently that is not the case and I will eventually have to do something to remedy the situation.  For now, however, the solution will be to not use the radio when someone s watching television.

 

2015/06/13 (S) On to Illinois

It has turned out to be a wet June so far and we had more heavy rain last night.  In spite of waking up during the night I was up at 7:30 AM and made coffee.  Everyone else got up as suited their level of rest and we sat around chatting for a while.  Ron put a load of laundry in the washing machine and then we sat down to a light breakfast.

Ron and Mary spent most of the rest of the morning repacking all of their stuff for the drive to northwest Illinois and their week-long bicycle ride.  FedEx Home Delivery delivered the Cyclo 5-Pro Mark II Dual Head Orbital Polisher I ordered along with all of the foam pads and detailing chemicals.

Ron retrieved their laundry from the dryer and after they finished packing we had a light lunch.  By 1 PM they were ready to load up the car so we helped get their bags out.  After a brief “farewell and safe travels” they were on their way.  They had a five hour drive but would gain an hour as they entered the Central Time Zone so they would be at their motel by 5 PM local time with plenty of daylight and time to eat dinner.

Linda took a short nap and then went for a walk.  I read through the manual for our SureCall Fusion5s cell phone booster and was part way through the manual for the Cyclo 5 when I decided to take a nap.  Linda returned from her walk and a little while later a USPS mail carrier delivered the OTA TV antenna I ordered from Antennas Direct.  All I am waiting for now is the cable entrance box I ordered from KF7P Metalwerks.

Once the cable entrance box arrives I will have a bit of a project.  First I will need to drill two 2″ holes through the east wall of the house and into the sump pump closet in the northeast corner of the basement, mount the box to the wall, and ground it to the outside ground rod by the tower.  I may also need to install additional ground rods.  I will then need to climb the tower by the house and do the following:

  1. take down the old OTA TV antenna and rotator;
  2. mount the new OTA TV antenna and aim it;
  3. mount the amplifier for the OTA TV antenna;
  4. attach a short piece of 75 Ohm co-ax from the antenna output to the amplifier input and weatherproof the connections;
  5. attach a longer piece of 75 Ohm co-ax to the output of the amplifier and weatherproof the connection;
  6. mount the outside antenna for the cell phone booster system;
  7. attach one end of a 50′ piece of LMR-400 or RG-213 co-ax to the cell phone antenna and weatherproof it;
  8. unmount our Diamond SG7900 2m/70cm ham radio base station antenna and remount it at the top of the tower;
  9. attach a 50-to-60 foot length of LMR-400 or RG-213 co-ax to the ham radio antenna;
  10. dress and secure all of the coaxial cables with plastic cable ties (zip ties).

Once I am done with tower work I will need to do the following to complete the installation:

  1. install the lightning arrestors in the cable entrance box for the cell phone booster and OTA TV (?) co-ax cables;
  2. route each of the co-ax cables into the bottom of the cable entrance box and attach them to appropriate lighting arrestors;
  3. attach additional co-ax cables to the lightning arrestors and feed them through the 2″ holes into the basement;
  4. mount the Surecall Fusion5s in the sump pump room and connect the co-ax for the outside antenna and the power supply;
  5. run a 50′ length of LMR-400 from the sump pump room across the basement ceiling and up through an old vertical furnace exhaust chase to the attic;
  6. drill a hole in the ceiling of the main floor hallway near the chase;
  7. mount the inside done antenna for the cell phone booster system to the ceiling with the co-ax dongle in the attic;
  8. connect the antenna dongle to the co-ax coming up from the basement;
  9. run additional co-ax from the sump pump room to the ham shack;
  10. run additional co-ax from the sump pump room to the video distribution point in the laundry room (or directly to the locations of the two TV sets);
  11. turn on the Fusion5s booster (transceiver), adjust the gain (if needed) and test it with our phones and Mi-Fi;
  12. test the TV sets (and hopefully not have to go back up the tower to reposition the antenna);
  13. connect our Icom IC-7000 amateur radio and test the antenna connection.

As I wrote out this list it occurred to me that I need to make a list of all of the co-ax types/lengths/connectors I need and that, at a minimum, I probably need to order a length of LMR-400 orRG-213 co-ax cable and the proper N-connectors to complete the ham radio antenna connections.  It also occurred to me that I might be able to do some of the inside wiring while I am waiting for the cable entrance box to arrive.  Also, once the TVs are connected Linda can scan for channels and communicate with me with our HT ham radios if I need to change the aim of the antennas on the tower.

All of this reminded me that I need to follow-up with a Bratcher Electric on running a new 100 Amp main feed from the transfer switch to the panel in the furnace room in the garage.  I also need to order some new split foam fillers from Critter-Guard and new electrical hardware for connecting the bus to the toad from EZ-Connector in California.

I must have been sleeping lightly and dreamed all of these details because I got up from my nap around 5:30 PM, finished reading the manual for the Cyclo 5, and then took a shower and got dressed for dinner.  Barb Spera had called Linda yesterday to see if we were available for dinner this evening.  They had really enjoyed our meal at La Marsa in Brighton a couple of weeks ago and wanted to go again so we agreed to meet them there at 7 PM.  We did not have to wait for a table and our waiter, Najheem (Naa-gheem), was delightful.  Barbara had the Koshary again, and Chuck had the Chicken Shwarma with tabbouleh salad, while we split an order of spicy vegetarian ghallabah with rice and a salad.  I had a mango smoothie and we all enjoyed the swarm pocket bread and garlic spread.

It was after 9 PM when we got home and we headed off to bed at 10.  We knew Ron and Mary had arrived at their destination because Ron played a Scrabble word.  Linda had also checked that our daughter and son-in-law were on their way back from Las Vegas.

 

20130819-26 E-mail Problems

It seems there is less to blog about when we are at the house, or perhaps there’s just less time to do it.  It’s not that we are less busy; it’s just that what we are doing seems potentially less interesting.  Besides the usual chores that go with owning a house, I spent the last week dealing with our pull-through driveway, ham radio stuff, and a serious e-mail problem.

By Wednesday the 20th it had become clear to me that we were not getting replies to e-mails we had sent out; not a couple of e-mails to a couple of people, but lots of e-mails to lots of people.  Most of these were e-mails to people who normally reply in a timely manner, and they were e-mails seeking information or continuing a conversation, and thus replies were expected.  I started making phone calls and sure enough our e-mails had been received and replied to.  We never got the replies, and the senders never got bounce-backs; the e-mails just vanished into cyberspace.  In one case I sent a single e-mail to two recipients, both of whom had gmail accounts.  They both replied.  I got one reply and not the other.  We also had a couple of folks send us e-mails while we were on the phone with them, but those e-mails never arrived.  Not good.

I opened a support ticket with our hosting service and spent the last week trying to communicate with their off-shore technical support people.  I don’t have prejudice towards off-shore support, but in this case they turned out to be neither sufficiently technical nor supportive.  Every time I updated the support ticket I got a reply from a different person.  I explained repeatedly and in considerable detail the difficulties we were having and they repeatedly sent replies apologizing for the inconvenience, asking me to send them information I did not have, performing simple but irrelevant tests of our e-mail accounts, and then informing me that everything appeared to be working fine.  Arrrgh.  As of this post the problem persists and I have lost any hope of it being resolved.  I hope to accomplish this with minimal downtime or disruption of service.  Our apologies to anyone who was affected by this; we have not been ignoring you and we now know that you have not been ignoring us.  We will be moving our domain to a new registrar/hosting service at the end of this month.

We have a tower that sits at the east end of the house.  It was already installed when we bought the house, and I estimate its height at about 38 feet; not that tall by ham radio standards, but tall enough to treat with respect if you are going to climb it.  It’s an older design and has obviously been there for a while.  It has an over-the-air (OTA) TV antenna on a rotor at the top.  The rotor is not connected to a controller and the coax is not connected to anything inside the house.  There is also a Direct TV satellite dish (single LNB).  The cables from that are also not connected to anything in the house.  The previous owners left the SAT-TV receiver behind, but it is obsolete.  The base of the tower is set in concrete but the tower was not secured anywhere else.  On Friday we rigged up a couple of support arms and attached them to the side of the house in anticipation of climbing the tower on Saturday to remove the old antennas and install our 2m/70cm ham radio vertical antenna.

On Saturday we went to our ham radio club (SLAARC) breakfast in South Lyon.  It’s always good to visit with this group.  Many hams are tech savvy about a lot of things besides amateur radio so I got to bounce our e-mail problem off one of them.  Thanks Larry (K8UT).  After breakfast Linda and I went to Mike’s (W8XH) QTH (location) to look at his ham radio tower as we are trying to figure out what to do for base station antennas.  He has a Heights Tower with a motorized fold-over base.  It is a very nice all-aluminum tower and a very nice installation.  Nice antennas, too, but that’s another story.

Mike then came to our house and brought his professional grade climbing harness.  We got it adjusted to fit me and I climbed up as far as the roof, probably 10 feet off the ground.  (Our tower is only an inch from the gutter.)  As I started up the tower from the roof, the tower had more movement than I was comfortable with, so we abandoned the climb.  I removed the old Direct TV antenna, which was at my shoulder level when standing on the roof, and installed our dual band VHF/UHF (2m/70cm) vertical ham radio antenna at the same height.  The dual-band is lower than I wanted and very close to one of the tower verticals, but it was the best we good do at the moment.  We routed the coax to the back deck, connected it to our Icom 7000 go box, and started looking for 2m and 70cm repeaters.  We were able to activate the K8VJ 2m repeater in South Lyon without difficulty, as well as the Livingston County LARK 2m primary repeater.  We were also able to talk to two guys on the Clarkston 2m repeater, which, according to the ARRL repeater directory that Mike installed on his smartphone, was over 22 miles away to the northeast.  Not bad for 2m on 50 watts with a less than ideal antenna location.  We tried a number of other repeaters but were not able to raise them.

While we were out taking care of ham radio business during the morning, Phil (our pull-through driveway contractor) brought a large load of sand (silt, technically) to the house, pulled the top 6 inches of 21AA road gravel out of the new pull-through drive, and mixed in the sand as he put it back.  As I noted in a previous blog, our bus got stuck in the driveway a couple of weeks ago and had to be winched out.  The problem turned out to be an inadequate amount of “crusher dust” in the 21AA road gravel.  Without a sufficient amount of fine particles, the larger stones don’t bind together and pack to make a hard surface that resists blowout and further compaction.

Mike spent the rest of the day at our house helping us with some computer issues.  He is a retired HP tech and now has an active business of his own working on personal and business computer systems and networks.  By the time we were done it was dinner time, so we treated him to dinner at Olga’s in Brighton.  Thanks Mike.

Sunday is our day to go to the Howell Farmers Market.  The fruits and vegetables are now plentiful and we picked up an assortment of yummy things.  We also got some pointers from Marjorie about apples and pears as we had discovered just a couple days earlier that we have an apple tree and a pear tree, both of which are laden with fruit.

On Sunday afternoon I used our Honda Element to “roll” the pull-though driveway.  The car only has about 1,000 pounds on each tire, so it is in no way equivalent to driving the bus, which has 7,000 lbs on each of the front/steer tires, 5,000 lbs on each of the four drive tires, and 3,750 lbs on each of the two tag axle tires.  Still, the car did a nice job of compacting the surface.  Phil had suggested that I carefully pull one of the front tires of the bus onto the pull-through driveway, but even after rolling it with the car I was nervous that it wasn’t locked together quite as much as it needed to be.  I had also heard from Ed & Betty Burns that they would be arriving on Wednesday in their Tiffin Phaeton, so I was anxious to make sure the driveway would support their motorhome.  I discussed it with Phil Sunday evening and he said he had a plan and would check in the morning to make sure it was going to work.  He was confident, however, that Ed & Betty would not encounter any driveway difficulties.

Monday saw us in west Dearborn for our summer dental checkups.  One of my old fillings was starting to separate from what remained of the tooth, and I was informed that it was time to get a crown.  They had a 9 AM appointment slot available the next day, so I signed up.  Dental work doesn’t bother me the way it does some people.  The sooner it’s fixed the better.

Jim and Kristine Gullen came over for dinner on Monday, the first time they have been to the new house.  Linda made a mushroom risotto using Farro, a wonderful, ancient, high-protein Italian grain that is earthy, slightly nutty, and has great “chew”.  She used mushroom “broth” instead of stock, of course, but that just added to the earthiness of the dish.  She served the risotto with a side of mixed green and “long” beans lightly sautéed in olive oil.  We got the long beans from an Asian vendor at the Howell Farmers Market who told us they are usually stir-fried.  How long are they?; about 2 feet, on average.  They taste like green beans although subtly different.  Linda also made vegan chocolate cake that was excellent and served it with fresh strawberries.  Jim and Kristine brought a couple bottles of wine and we had a wonderful visit over a lovely meal.

Phil came back late Monday afternoon and added some more sand to the edges of the pull-through driveway and also to where it ties in to the concrete driveway.  He had borrowed a compactor device that mounts on the arm of his backhoe and used that to compact the driveway.  I don’t know about Linda, Jim, or Kristine, but the sound of Phi’s equipment working was music to my ears.  The song was “Our bus ain’t gonna sink no more.”
