Executive summary: After over 25 years of radio silence on the HF ham bands, I am back on the air!
= = =
Friday afternoon I got off work a little early and the weather was sunny and relatively warm for March, so I went out to the yard with a spool of wire and marked off how long I thought the antenna would be, cut the wire to length and created the radiating part of the antenna. Saturday I attached the feed line, started hoisting the assembly, and at that point I learned a few interesting things:
1. The antenna goes right through the Asian pear tree, and a couple of branches are very close to it. This is not a problem at the moment; I hope it does not become a problem during the next windstorm, or when the leaves appear on the tree. The tree isn't pushing down on the wire or anything, but it could hit the wire if the wind is blowing. (I have tried to put a little slack into the system with bungee cords on both ends of the antenna. We shall see.)
2. The layout of the fence I attached it to necessitates a 120° bend for the last few feet of the wire. This should not be a problem as long as the lengths of the two ends are equal (they are, or as close as I can measure).
3. The topography of the back yard is such that the antenna's height above ground varies from 20' at the house end to 6' at the fence end. Since the rule for antennas is "get as much wire as high in the air as possible," this could limit the range of the antenna, especially at lower frequencies. (See below) All antennas are compromises, though, and this was the compromise antenna I could get up on my own.
So this is not an ideal antenna, but since as I said all antennas are compromises, I can live with that. I got it up in the air, went inside the house and started checking it out. I got an acceptable match to the transmitter on all the bands 80 through 10 meters, and maybe 6 as well.
Now for the real test. Can I get a signal over the fence? I tuned up on 40 meters, listened for a clear spot, and called CQ on CW (Morse code). I took it rather slow; after 25 years I remember most of what I knew before, but the letters weren't coming as naturally as I would have liked. Do I sound like I'm sending with the wrong foot? Is anyone going to come back to me?
No answer.
I did this about three times and then heard:
STN CALLING CQ? DE **** *** K
That isn't usual – most of the time the other station will respond with your call sign, "DE" (meaning "from") and their call sign, followed by "K" (go ahead). In my surprise I completely missed their call. Well, I decided, let's go for it.
QRZ? QRZ? DE WA7KPK WA7KPK K
"Who's calling me? From WA7KPK, go ahead."
WA7KPK WA7KPK de KA7PUN KA7PUN
My first HF QSO of the 21st century! KA7PUN was a bit hard to copy, but I managed to get most of what he said. His name is Dan, he lives in Benes, New Mexico, he's retired, and he likes flying ultralights and helping new hams get up to speed on Morse code. (More about that in another blog post.) He was quite a chatterbox – we were on the air for over an hour.
Sunday the antenna was still up, so I tried a couple more contacts, this time on a digital mode called PSK31. Without getting technical about it, it's a mode where you type your text into a computer window to send and watch the replies as they scroll across your screen. A little like connecting to a BBS. With a 300 baud modem. Yeah, ti's a bit slow, but so?
I had to cut the first PSK contact – with Bruce in California – short because the ham I was talking to was fading in and out. That had happened with Dan also, and I am hoping that's just atmospherics and not something that's happening because of the (lack of) height of the antenna. Not long after I found a nice strong signal, replied to it . . . and found myself talking to Zach in Lake Forest Park, a distance of about three miles. No wonder he was solid copy.
Later that night after I finished with my 2 meter FM nets I went back down and called CQ on PSK again, and got another strong signal. Great, I thought, we're making progress.
"Name is Creede," I sent, "[location] is Shoreline WA"
Geoff replied, "I am almost on top of you, I am down near 130th Street."
Heh. Geoff lives on Ashworth, which the street just to the west of my house, and maybe about 2 miles south.
So yesterday I made contacts totaling about 1000 miles, 995 of which were to California. :-)
I think the prospects are good for getting out of my back yard with solid readable copy. For one thing, there was the contact with Dan in New Mexico (the fading notwithstanding). For another, I was able to copy other conversations going on involving hams in places like Colorado, Wisconsin and Ohio, and copy them solidly with no fading.
So maybe this antenna is a cloud warmer (an antenna that generates signals with a high takeoff angle, limiting the distance signals can travel), and maybe it's just fine and will let me work Bora Bora, and maybe it depends on the frequency and time of day. Doesn't matter. It's my antenna and I'm enjoying it greatly so far.
The real test will come tonight and Sunday morning. There are two nets I want to check into on 80 meters (the lowest band I can get the antenna to work on, and even then it's a bit iffy). We'll see if I can check into them.
In other news I am coming down the home stretch in practicing for Norwescon. I need to finish the song I'm working on.
