My antenna has been defective for months now. The feed line had broken loose from the radiating elements, making the whole thing useless. Last fall I ordered a commercial replacement, a somewhat better-constructed version of the same design, but when it came the bad weather had already set in. Lowering a 100 foot long antenna and raising a replacement in ice and snow... Well, it could be done of course, but I didn't need it that badly.

One of the things on my to-do list for this week was to finally get the old antenna down and the replacement up. Did that today. It turned out to be easier than I'd expected. In spite of the fact that the nylon ropes holding up the old one had been in place up in the trees for ten years, they still were strong and had not bound up in the bark so they slipped right down. We figured out how we had threaded the 102 feet of copper wire through the tree branches last time, and by using the old lines to pull the new ones into place, and then the new lines to raise the copper, we got it up there. The old one worked so well that I'm quite confident this will be great.

(For the radio geeks, it's a G5RV style doublet, full sized, with 450 ohm ladder line feed from an air-core coaxial balun. 102 feet on top, height above ground about 36 feet, orientation roughly NW-SE. I use a pi matching circuit for low power operation on HF, 80-10 meters. The orientation seems to help me work into Europe and the South Pacific easily, but Africa and Asia are not quite so good. And it won't sing on top band. I need to do something else for that.)

Now to replace the 2 meter vertical. I really need something for both 2 m. and 70 cm. And I've never had a 6 m. antenna at all...

Enough. There's a thunderstorm here, need to close stuff down.

Though I've had an amateur radio license for 25 years now, and have had call sign plates on my car since about 1987, tonight is the first time that someone ever approached me and actually asked about becoming a licensed radio operator. Most of the reaction I get is just "Oh, you're one of those strange people?" and quite typically, a lot of confusion about the difference between amateur radio and CB. (They have virtually nothing in common, folks.)

A regular library visitor who spends hours on his laptop connected to our internet link, asked me about it right at closing, because he'd seen the plates on my car. Apparently he was interested in the subject at some point in the past, but never got far enough along to actually get his license.

He didn't know, for instance, that the US no longer requires a morse code test of license applicants, or that modes that use computers to communicate over radio links are becoming increasingly popular.

Unfortunately, I think what he was really looking for was a pointer to a license training class, and I don't have that information. But at least I could tell him where on the web to begin looking.

Slow drippy rain continues, good for the stuff already planted in the garden, but introducing delays in getting the rest into the ground. Sheep get sheared on Saturday. Car goes in for 6000 mile service in the morning. And I have to go to bed.

Typical blah Monday. Staffing is going to be short (as usual) this week at work. Getting so this is a regular thing.

Thanks to several folks on [livejournal.com profile] radiofurs I've got some basic ham software going under Linux now so hopefully I can get away from having to run Windows on VMware in order to have control of the transceiver and soundcard. Band conditions are not great, at least, not on 40 meters. I did put a few calls out, and I think there were a couple of responses but they were so far down under the general noise that I couldn't read them for sure. Oh for a few sunspots. Hopefully we've about hit bottom on that and will start seeing some improvement by the end of the summer. At the moment I should flip the switch on the radio and do some other stuff that is more urgent.

Got up into the 40s today, which is almost seasonal, but I guess it's going back down with rain and snow by tomorrow night. Sigh.

Time for this cloudy, cold weather to dissipate. I know, I know, April showers and all that. But it's not showering, it's just glooming. And cold. Too cold.

Another indoor day, except for necessary chores. Gotta go do evening feed and water routine in a minute here, too. Played with the radio some more. Gosh, with this hookup I can do SSTV as well, something I've never played with much because it used to take pretty expensive equipment. Made a couple of contacts with the PSK31 mode this morning, but conditions aren't great. Time for the sunspots to come back. Got the software set up for simple RTTY too, but no one to try it out on.

We have hundreds of daffodils in a holding pattern, partly open but stalled by the absence of sun and warmth. One of the ducks, however, saw fit to deliver an egg this morning, first one of the year. Each year it gets later, the poor hens are getting old like me.

Well, off to the barns. Then I think I may actually fire up the wood stove.

Ham radio geekery behind cut )

Cleared up today and we had sun all day. It's cold, though. C'mon, it's mid-April almost. We should be getting over this freezing nights and chilly days stuff. Even the daffodils looked cold, trying to close themselves back up. Did just small stuff at work this morning, and now a long weekend. Not that I'll be relaxing a lot, too many things that need to get done. Dull stuff, like ironing and housecleaning. A newsletter to get out and a writing project to finish. Oh well, at least the cold is finally losing its grip on my insides.

It's winter again. Snow flurried much of the day, though no accumulation. Temperatures down to 20° at night again. We may have to break out the wagon and buckets again for a few days.

Cleaned off some of the junk on my desk at home. I'm finally getting all the parts in one place to put my FT817 on the air using PSK. For those not familiar with ham radio jargon, that's a digital mode that sends text back and forth over the radio so it looks rather like an IM session. The signal is modulated and demodulated in the sound card of the computer. To the ear, it sounds rather like a rabbit whistling Dixie. ;p

Only half a day tomorrow, and then a long weekend. Maybe by the end of it I will finally have shaken off this cold thing.

ung...

I sure hope there's a chance to get some rest this weekend, 'cause this has already been too long a week.

Tomorrow the directors of the rebel libraries come to meet at our location because we'll be so shorthanded that my boss didn't want to be unavailable if we were hardpressed. And it's the day when elementary school classes visit, sometimes as many as five or six classes during the day, which is an absolute zoo (and not in a good sense.)

Spent my morning setting up a computer in the meeting room so that the directors can use it to draft their documents during the meeting. Then writing down a list of carefully explained reasons why we find the proposed software of the merged groups unacceptable (that wasn't hard, but making it coherent and clear was time consuming.)

Then off to a study group meeting from my spinning guild. Got home after 4 pm and had to clean barns and feed everyone and bed them down. It's cold here. I have the woodstove going now, and though it's not even 9 pm, I really need to go to sleep. Something about the day has really worn me down.

Oh, and a small fun thing. My certificate and membership card for QCWA (the Quarter Century Wireless Association) arrived in the mail, which means they accepted my qualification for membership. It's an organization for radio amateurs who have been licensed for at least 25 years. (Or more properly, who were licensed at least 25 years ago and are licensed today. Lapses in between are permitted, though mine has been continuous.)
