Stuff

If you live in the midwest in the US you don’t need me to tell you that the weather hasn’t been very good. Unusually cold temperatures and seemingly non-stop rain has been hitting large parts of the midwest. Corn and soybeans were, for the most part, planted late or even not at all. Ohio seems to have been hit the worst. Looks like almost 25% of the Ohio corn crop isn’t going to be planted at all. The situation with soybeans isn’t quite as bad, but the numbers there aren’t looking very good either.

The exact numbers are uncertain because a lot of farmers and people in the ag industry are being openly, even brutally skeptical of the data coming out of USDA. There are claims USDA is including acreage that has been planted but is under water and will never grow, acreage that has been planted with cover crops instead of corn because it’s already too late to plant, etc.

I can’t confirm or deny any of those suspicions. All I know is that when I ride around the countryside I’m seeing a hell of a lot of fields that look like the picture there on the left; lots of mud, lots of standing water, and lots and lots of weeds. It is too late to do anything with fields like that except to try to plant a cover crop to keep down the weeds and prevent erosion. You aren’t going to get any kind of economically viable crop planted in this area, this late in the season.

What about hemp, you ask?

Well, okay, you didn’t ask, but I’ve had a couple of people ask me about what the situation is with hemp. It is now legal to plant, harvest and process hemp here in Wisconsin, and despite the fact that a lot of people have been hyping the hell out of it and claiming that it is going to be the savior of agriculture, well, hemp, so far at least, has been pretty much a total bust for those few farmers who’ve tried it. Raising hemp for grain was a total loss last year from what I heard. Because of wet fall it was almost impossible to harvest the stuff. And what they did get harvested was hit by mold because of the damp weather so they couldn’t sell it at all.

Instead of depressing stuff, how about some pretty flowers instead? This is alyssum growing in my backyard. Wonderful stuff. Beautiful tiny, tiny flowers that produce some of the most amazing scent imaginable. I love this little plant. Those flowers are very small, about the size of a match head.

Raising it to produce CBD oil didn’t work out too well either for a lot of farmers. One farmer I heard about did successfully get his crop in, but trying to actually sell it was a different story. It seems no one actually wants large amounts of the stuff. Or none that he could find, anyway. None of the CBD oil producers he’s dealing with seem to want more than a few pounds of it at a time, and you can’t make money that way. His problem is marketing, of course. It sounds like he jumped into production before he was even sure if he could sell the stuff.

Hemp isn’t going to be “the savior” of agriculture. It is, at best, going to be just another crop that some will have success with. And all of the hype about CBD oil seems to be mostly that, hype, with few actual facts to back up any of the claims. There seems to be some indications it can help with epilepsy and discomfort from arthritis, but that’s about it.

Antenna Stuff

Strange things are growing in my backyard behind the garage. No, that’s not some kind of weird sunflower, that’s a GAP Titan DX vertical antenna which has been laying around for years now. Eldest son and I finally got the dopey thing put up over the weekend. That thing has been laying around for, oh, lord, has it really been three or four years? Sheesh… Talk about procrastination…

It replaces the Comet 250 vertical that was back there since 2013. The Comet – people like to complain about it but to be perfectly fair it wasn’t a horrible antenna. It is exactly what they claim it is, a multi-band vertical that doesn’t need radials or a counterpoise, that works from 80 to 10 meters without an antenna tuner, and can handle up to 250 watts. It is unobtrusive, the neighbors probably won’t complain about it, and under the right conditions it will even work as an antenna. Sort of. Not a very good antenna, true, but it will work.

The Titan has a pretty good reputation. It too is an all-band vertical, but you can see that it isn’t exactly simple, with all kinds of stubs and wires and stuff coming off it. But it is much, much more efficient than the Comet. And I can feed this one up to 1,500 watts if I want to without damaging it, where the Comet, well, I heard reports that if you tried to put more than 100 watts into the Comet you’d melt down the coils. Anyway, I still have work to do on this one. I need to get the counterpoise installed, need to get some connectors on it, need to tune the stubs. Hopefully it won’t take me another four years to get it hooked up!

It’s up high enough so it won’t interfere with the flowerbeds behind the garage. The counterpoise will take up a bit of space so I imagine MrsGF will not like that, but I’m hoping to get her to upgrade to a general class license now that she’s retired and if she does she’ll get as much use out of that antenna as I will.

Speaking of flowers, (well, okay, I wasn’t speaking of flowers but what the heck) the lupins have just gone nuts this year. They’re everywhere. It looks like someone bombed the entire backyard with seed. We didn’t plant any of these, they just came up by themselves. Not that I’m complaining. Those flowers are spectacular.

Let’s see, what else? Oh, yeah…

Stuff On The Air

Amateur radio operators can be a bit, well, odd, shall we say? (Personally I suspect it’s solder fumes.) Some of them seem to be obsessed with lugging their equipment out of the safe environment of their basements where spouses have exiled them and into the great outdoors with the intent of doing “Things On The Air”. They do SOTA (summits on the air), IOTA (islands on the air), POTA (parks on the air) WPOTA (Walmart parking lots on the air), and, well, the list goes on and on.

I’ve decided to join the ranks of these intrepid and brave explorers going to exotic places and sticking still more letters in front of “OTA”, risking life and limb outside of the safety of my normal operating location. Yes, I’ve started FPOTA! Front Porches On The Air! Ooo, the excitement! Ah, the thrills!

The plant there is important. It adds about 0.001 dB to the gain of the antenna.

Well, okay, I’m being silly here. (But to be honest I’m getting really tired of these “OTA” things and people running around “activating” parking lots and hills and parks and bridges and I don’t know what all else.) Still, we had a very rare nice day so I set up the mag loop and the 818 out on the front porch with a cup of coffee, a copy of “The Bathroom Reader” and and contacted, well, no one, to be honest. Chris over at Off Grid Ham tells me he’s been having similar results and not to feel too bad about it. Propagation on the HF bands pretty much sucks because we’re at the bottom of the solar cycle.

By the way, if you’re at all interested in solar power, batteries, solar controllers, and alternative ways of keeping your radios running, battery charging systems, etc, Off Grid Ham is the place to start.

The Great QRP Saga Continues

If you’ve been reading this nonsense for the last couple of weeks you know about my efforts to put together a portable QRP (low power) radio setup that’s small enough I can throw it into the back of the car and take with me when I go fishing and stuff so I can do PTOCCOTA (Picnic Tables Of Calumet County On The Air). Okay, I’m being silly, but I have long wanted to have a nice QRP set up that I could take along with me to play amateur radio while out enjoying the glorious environment of Wisconsin’s great outdoors and it’s swarms of blood sucking, disease carrying mosquitoes and ticks.

I’m mostly interested in digital modes of communications like PSK, FT8 and JS8 because despite the fact my hobby is communications technology, I don’t like to actually, well, talk to people. Yeah, I know. Weird, isn’t it?

So as you may recall, the ancient Toshiba laptop I was going to use decided it was time to go to that great recycling center in the sky. So I’ve been scrounging around for a cheap (emphasis on cheap because I already got way too much money invested in this project already) replacement and came up with this:

It’s a refurbed Lenovo that I picked up for $300 and, frankly, it’s ridiculously nice. I mean this thing looks and feels literally like brand new. There isn’t a single scratch or smudge or physical defect anywhere on it. Has a core i5 processor, 8 gig RAM, 500 gig SSD drive, DVD drive, 4 USB ports and seems entirely too nice to lug around out in the field. I have FLDIGI, JS8Call and FT8 software installed on it already. And I think I have the right cables to hook everything up to the SignaLink and the 818. So this weekend I’ll be taking over the dining room table for a few hours and see if I can actually get all this to work together.

I am not looking forward to that because, well, it’s embarrassing. I’ve been working with computers since 1979, both hardware and software. I’ve been fiddling with radio for even longer even though I didn’t get my amateur radio license until 2013. I was an electronics technician. I repaired laser scanners, set up computer networks, worked with ridiculously complex point of sale systems. So I ought to know this stuff, right? But whenever it comes to trying to hook a computer to a transceiver it quickly turns into an extremely frustrating experience. It never, ever works the first time. Or the second. Or the third. Or the fourth… Well, you get the idea.

I spent days trying to get Ham Radio Deluxe to work with first my Kenwood TS-2000 and then later with the Kenwood TS-990 and a RigBlaster Advantage interface. It was so frustrating that at times I was ready to just give up and then, for no apparent reason, the damned thing would just start working, with the same settings and cabling that didn’t work the day before… Arrgghhhh! The last time I had to rejigger stuff was when I got the new gaming PC and was trying to hook that up. Same settings, same cables, same everything, and, of course, it wouldn’t work right. Ham Radio Deluxe worked just fine and dandy until I wanted to transmit. Then it would key the transmitter but nothing actually transmitted… I struggled with that problem for way, way to long. And then it just started working for no apparent reason… I still don’t know what the hell happened there.

Anyway, enough of that. I’ve been boring you long enough with this stuff. Hopefully come Monday or Tuesday I’ll be able to report that I’ve got the 818 working flawlessly with the ThinkPad and I’m making contacts all over the place.

I doubt it, though.

Autumn and Garage Sale Find

We’ve finally moved into more typical autumn weather for Wisconsin. The heat and humidity were finally pushed out of the state and we’re going through more typical weather for this time of year. We still haven’t had a frost yet as of Oct. 6, but that will be coming soon. But even fall couldn’t arrive in a typical fashion. After a few days of crisp, cool weather with temps in the low 50s, the heat and humidity pushed back in for a day, with temps up in the mid-eighties with high humidity, triggering more rain and storms which we didn’t need at all. The Manitowoc County fairgrounds got hit by what was either straight line winds in excess of 75 mph or a weak tornado.

IMG_0037It may be October but there are a surprising number of flowering plants still bopping along as if it were still summer. I’m still seeing a huge number of bees, both native bees and honey bees. That’s kind of unusual for this time of year, but as long as the temperatures are still warm enough for them to be active and there are still food sources out there, they’ll be around.

I found this thing sitting in the basement the other day and had no idea where it came from.

IMG_0031

I learned that eldest son found it at a garage sale for $5 one day and picked it up and, of course, it ended up in my basement. Well, I’m claiming this one for my own because I’m fond of old Hallicrafters equipment. I have two restored Hallicrafters short-wave receivers from the 1940s-1950s era and I love the things. This one looks like it’s in good enough shape cosmetically that it might be worth restoring. I haven’t done any research on this model yet, but judging from the way it looks I’d say it’s from the late 50s or early to mid sixties.

Once upon a time you couldn’t give away old tube radios. Thousands upon thousands of them ended up going to the landfill because no one wanted them. Now they’re turning into collectors items. Sort of. Prices on these things are all over the place depending on the brand, model and age.

There are issues with restoring old radios like these. Some of them pretty serious and if you don’t know what you’re doing, they could even be life threatening because of the dangers of electric shock. Depending on the radio and the design, some of these things had potentially lethal voltages floating around inside of them. So if you don’t know much about how these things were made and the potential dangers, don’t go fiddling around inside of them without educating yourself first.

The other issue is you can’t just plug these things in and turn them on if they haven’t been used in a long time. When it comes to these old radios, there is no such thing as “mint” condition except when it comes to the external appearance. You will always need to replace components inside with modern equivalents. Capacitors are the biggest issue with these. Those old caps will fail. There is simply no doubt about it. Usually the first thing you do with one of these is go through it and replace all of the capacitors right off the bat.

Another issue is finding things that can’t be easily replaced with modern equivalents, like vacuum tubes. Under normal operation vacuum tubes are amazingly long lasting. I know guys running old amplifiers, receivers and transmitters that are from the 1940s and 50s and are still running the original tubes. But they do fail sometimes, and finding replacements is a problem because they haven’t been made in decades. If you have an old tube radio, chances are good the tubes will still work unless the radio was abused or had some kind of electrical failure. But if you have a bad one, finding a replacement tube could be a problem.

Anyway, when I get some time I’ll open this one up and see what it looks like inside. It might be a good candidate for restoring.

Amateur Radio Stuff: What’s Going On

It’s been quite a while since I mentioned mentioned amateur radio, but that’s been because of a lack of time, not a lack of interest. Things back in the radio room are about to get — interesting, as they say. I’m facing a situation that every amateur radio operator does sooner or later, having to tear down everything.

IMG_0356
It’s even worse than this looks here. There are two more desks crammed into that room, an old drafting table, three book cases, a work table… It’s bad.

The radio room is, to put it bluntly, a mess. There is equipment piled everywhere, test gear shoved onto book cases or in drawers, amplifiers and radios laying on the floor, piles of printouts of manuals, booklets, stacks of mystery electronics in those anti-static bags, drawers full of connectors and parts, coax jumpers, meters, microphones, tools three full sized computers, three printers, all my Raspberry Pi stuff. There are cables and wires snaking along behind the desks, running into holes in the floor. The operating position is too cramped and awkward. The old drafting table my solid state amp is parked on it is too tall and too small, the desk the radios are on is in poor condition. The list goes on and on.

So everything is going to get torn down, moved out of the room. The room is going to get a good cleaning, etc. Then I start trying to put everything back together.

What sparked this is that MrsGF found a huge old teacher’s desk, made out of solid oak, for $50 at St. Vinnie’s. MrsGF already has one of these and I’d been looking for one for a while. The finish isn’t very good and it has it’s share of scratches and scars, but it is rock solid, lots of big drawers, and is long, wide and deep. That is going to get moved in, some of the old, particle board crap I’ve been using is going to go away before it collapses under the weight of the equipment, and then I can start trying to put everything back together again.

If I can remember how to do it… Meters, jumpers, wires, coax. You’d think I’d know enough to label all that stuff, right? I mean I have a label maker laying right there. But no, of course I didn’t. Sigh…

Anyway, Monday is the day when I start all of this. It’s taken me three years to accumulate this mess and put together that rat’s nest of wiring behind the desks, so this could take a while…
