Attic Sidekick

 

In this final segment of antenna challenges, I want to take a look at some of the successes and failures. One antenna I tried was a screwdriver antenna ( High Sierra Sidekick) mounted in the attic with ground radials but for some reason, I was never able to get a good SWR.

 I then moved it outside at the side of our deck steps as I did not want the condo police to see it. With this setup I needed to setup and take down the antenna each time it was used.  To speed things up I buried the coax to the mounting location and I had a piece of 90-degree conduit attached to the deck step and it would swing out when I wanted to mount the antenna.

Sidekick outside.

The mount I used was called a Jawmount this allow fast install and take down.  I also buried the radials in the ground around the deck and out into the yard. This setup also meant I had to keep the snow cleared on the deck steps and around the antenna mounting position. In the end I wanted to have something more stealth and had better results as well as less trips out doors.

My next idea was the gutter and what I did here was used the center conductor from the coax and the braid was attached to the radials I used for the screwdriver antenna. The Elecraft K3 tuner was able to tune the gutter but I had a lot of noise and issues getting out. So it was back to the ground-mounted screwdriver antenna for now. 

 I also tried just plain old portable operation from home as well but that would be limited to summer time only. I set up on my deck using the Elecraft KX1 with the miracle whip antenna and also a portable mag loop. This was a nice setup with decent results but was limited to summers with nice days. 

Portable deck ops

The next idea I just can't believe I even did but I did and it worked very well. In the townhouse complex we lived in our cars were parked in a common parking lot we had no garage or driveway. Our home backed onto a large green space that connected to this parking lot. The gears in my head started turning..if I could get coax from the back of the house through the field to the car parked in the parking lot I then could put an HF antenna on the car and I would be good to go! Now that I look back I just can't believe I did this but I did. I purchased a large HF mobile multi-band vertical the Valor ProAm AB-5. Now it gets really good...I was able to get free from work 3/4 inch poly pipe. I rolled it out and bury about 60 feet of it in the green space almost to the car. Now that was a lot of work and done in such a way that it did not attract attention....don't ask.....Anyway fed LMR 400 in the pipe that I purchased cheaply at a flea market. The poly pipe was connected to a plastic waterproof box and the LMR 400 was terminated to an SO-239. When I wanted to get on the air I place the antenna on the car via a trunk lip mount and ran some RG8X from the antenna to the box where the LMR was terminated. This worked great for years and I was very fast at putting it up and down.

 Well as they say all good things come to an end...I came home from work one day to find the city decided to put a walking path in the green space and in the process dug up my poly pipe and LMR 400. I am guessing they had no idea what it was. They had already left for the day as I arrived home so it was time to move fast! I pulled out all the LMR 400 coax and removed from the ground about 15 feet of poly pipe that was close to the townhouse. Well, it was good while it lasted but now it was time to start thinking again. 

This was when I came up with the idea of the Alpha Delta in the attic (See part 1 in this series) Well that is it for my restricted antenna adventures and I hope you enjoyed and possibly came away with some ideas. 

Side note: Not sure what is going on with some of the text sizing in the post I tried to fix it and just ended up with more issues. Sorry for the sections of smaller print.

The FT8 mode was first released as part of the WSJT-X software in 2017. This new digital mode was adopted relatively quickly and is now a major force in amateur radio. You’ve probably heard the praises and complaints about it. On the plus side, it enables radio contacts under very poor conditions while detractors say that it is not real ham radio because the computer is making the contact. FT8 is an excellent example of a disruptive technology, impacting daily ham radio operations. This summer, I had two operating experiences (VHF contests) that really drove this point home.

My temporary station setup on the porch for the VHF contest.

ARRL June Contest

In the ARRL June Contest, we had very good sporadic-e propagation on 6 meters (and even 2 meters). I used my IC-7610 for 6 meters and usually had one receiver listening on the SSB calling frequency and the other sitting on the FT8 frequency. My strategy was to operate FT8 while keeping an ear on the SSB portion of the band. If signals were present on SSB, I switched over to that mode. The idea is that the run rate on SSB is inherently faster (and more fun), so it is my preferred way to make contacts. 

There was definitely activity on the SSB portion of the band, but it came and went throughout the contest. There were times that I was able to run on a frequency, calling CQ and having a steady stream of stations to work. Other times, I had to search and pounce, tuning around the band to find a new station to work. The FT8 story was different: most of the time there was consistent activity and new stations to work, but at a slower rate.

The FT8 operators tended to stay on FT8, even when the signals were strong. If they wanted to maximize their score, they probably should have switched over to SSB to make contacts at a faster rate. But they didn’t and that is their choice. (One thing I’ve come to accept is that I don’t control the choices that other radio hams make in terms of operating mode and band.) On 6 meters, I made 428 contacts with 80% of them on FT8. Radio operator decisions affect the types of QSOs made and if I focused only on SSB, I would surely have had more SSB contacts (but how many?)

CQ WW VHF Contest

In July, the CQ Worldwide VHF Contest was even more striking. While I was hoping for a repeat of the band conditions from June, the CQ WW conditions were not very good. However, I did manage to make QSOs using FT8 on 6 meters. The run rate was low and I often struggled to complete the exchange before the band shifted. Again, I listened on 6m SSB and picked up contacts there whenever possible. My QSO total for 6m was 164, with 90% of them via FT8.

After the contest, I heard from contesters that used only analog modes (SSB and CW) who reported that the contest was a complete bust. Even with hours of operating time, some folks only made 10 or 20 QSOs. This clearly tees up the choice: if you don’t want to work digital, you can severely limit your number of contacts. On the other hand, if you use FT8, you can make contacts under weak conditions, but at a slower rate with a computer in the loop.

Like many contesters, I would much rather have a nice run of QSOs on SSB filling up my log. It is just way more fun than sitting there watching the computer screen report the slow progress of FT8. But in the end, we all have the same choice when conditions are poor: actually making contacts using FT8 or sitting there hoping that band conditions improve enough to support SSB.

2 Meter Band

I did make some FT8 contacts on 2 meters, but found only a small number of operators using that mode. I expect that FT8 activity will increase on that band as people figure out they can squeeze out a few more contacts & grids using that mode.
