They’re claiming another major storm will roll through here starting to night. We have flood warnings, winter storm warnings, ice warnings, heavy snow… Well, considering they totally blew their last storm warning, we remain skeptical. Last Sunday we were supposed to have 8 or more inches of snow, high winds and blizzard like conditions and we got bright sun and mild winds. So we’ll see. But this time of year I always find myself paging through photos from warmer weather because I’m getting very impatient for spring to get here. So here goes. I’ve probably put some of these up before, but what the heck…
Because people know I like fiddling with radios, sometimes people give me old radios they don’t want or that don’t work in the hopes I can do something with them. I thought you might be interested in how your grandparents listened to radio, so take a look at this beast. I’ve had this thing sitting on the shelf for a long time now and finally decided to pull it out and deal with it because I need the space.
I have a term for radios like these – junk. It’s a shame, really. Once upon a time this was probably a nice little multi-band radio receiver. The rust on the chassis isn’t a big deal, that’s pretty common and can be dealt with, but this thing has some other, much more serious problems. It is unrepairable, but there are some useful parts I can salvage.
I looked all over this thing and I can’t find a manufacturer’s name or brand name. If I did some research I could probably find out what company made it originally, but there’s no real point because it isn’t worth the effort. There might have been a paper label that fell off long ago.
Or it’s entirely possible there never was a maker’s mark stamped on it. It wouldn’t be that uncommon. Like today, the name you see on the case of a piece of equipment isn’t necessarily the name of the company that actually made it. Back when this radio was made, big retailers like Sears and others would contract with manufacturers to produce equipment that the retailer would sell under their own brand name. Sometimes they’d buy the electronics from one company, buy the case from another, assemble it somewhere, slap their name on it and sell it as their own. It’s very common even today.
You’ll also note there is no outer case for this unit, either. That’s how it was when I got it. I find that fairly often today as well. Often the outer cases were made of cheap plywood with a thin veneer of nice wood on the outside to make it look fancy, and the cases would never last long. The plywood would begin to delaminate if it got damp, and they’d get damaged easily. Or if the case was in good shape, it’s fairly common for people to strip the old electronics out of it and throw them away and use the case as a decorative item or even build a modern radio into it.
Now if that radio up there looks complicated with the big transformer, variable capacitor, all the tubes and coils, well, you ain’t seen nothing yet. Wait until you see what’s underneath:
That – that mess up there, my friends, is what all radios looked like under the cover back in the day. When this radio was built, there were no transistors or solid state devices. This radio even predates printed circuit boards. Every single bit of this radio was built by hand. All of those components and wires were soldered in place by some poor schmuck who stood at a work station all day long doing nothing but soldering bits and nubbins and gubbins together.
Radios back then were very, very expensive, partly because they had to be all assembled by hand. It’s hard to tell how much this particular radio cost when it was new. Let’s say it was made in 1950, and it cost about $60 back then, which was a fairly common price for a decent, but not top of the line, multi-band receiver back then. That doesn’t sound like much until you take inflation into account. Accounting for inflation, that radio up there would sell for about $640 today. Ouch!
Another reason they were expensive was the sheer number of parts necessary, and, of course, these things:
Those are vacuum tubes. Now there is a wave of nostalgia going on about tubes, especially among stereo and audio aficionados who claim that sound amplifiers that use vacuum tubes sound “better” somehow, than those that use solid state devices and, well, it’s all BS, really. Vacuum tubes, to put it bluntly, suck. (Vacuum? Suck? Is there a pun in there somewhere? No, don’t go there…)
Sidenote: To give you an idea of how ridiculous this whole tube amplifier thing has gotten in the audio market, let me give you an example. An acquaintance of mine had a friend bring over a tube style stereo amplifier that had some problems. The four prominently displayed vacuum tubes on the top of the unit weren’t lighting up. But interestingly enough, it was still working as a stereo amplifier. Which it shouldn’t have been if the tubes were actually doing anything. Which they weren’t. The only connection to the tubes was a line to feed power to the filaments so they’d light up. None of the other pins were even connected. The tubes were being used for nothing but decorative lighting.
Vacuum tubes look really cool and retro and all that, but as actual electronic components they’re horrible. They suck up huge amounts of power, give off large amounts of heat, are physically large, often require massive transformers to provide high voltages, are expensive to make, and as soon as solid state devices began to be mass produced, radio manufacturers abandoned them as fast as they could redesign their equipment.
As I was looking this thing over, I found it had a rather serious problem. This:
If you look close at that photo up there, you’ll see what I mean, charred parts, melted wires – basically this thing was damn near on fire at one point. Probably some component failed, overheated, and started the insulation on the wiring on fire.
So what am I going to do with this thing? There are some parts I can salvage. The tube sockets are still good, and they’re hard to come by, so I’ll pull those out. The tubes themselves – I’ll keep ’em but I don’t know if they’re any good. They do make nice decorative items, though. Some of the big rotary switches may be salvageable as well. The actual electronic components aren’t worth even bothering with. A lot of them probably would still work within their original specifications, but without tearing them out of the circuits and testing them it’s impossible to tell, and frankly it isn’t worth the effort. Would you use a 50 or 60 year old resistor in a project you’re building today, even if a meter said it was within specification? I wouldn’t. But I am hoping I can salvage this:
These big air variable capacitors were (and still are) used for tuning, and they’re damned expensive if you have to buy them new. So I’m hoping that once I get this one out and cleaned up it might still be useful. It looks in pretty rough shape with some significant rust issues, but that seems to be limited to the nonessential parts. I can’t tell until I can pull it out and test it. I’m hoping it will work because a new one like this sells for about $50.
Is Repairing Old Radios Worth It?
Well, I’m not going to give you a whole lecture on antique electronics, but the answer to that question is … Well, to be perfectly honest, probably not unless it is something you personally enjoy.
Financially speaking repairing and refurbishing old radios is almost never worth it. You aren’t going to get much money for them unless they are something rare or exotic. Often the people who buy antique radios aren’t so much interested in them working, they want them for decorative items. Considering the amount of time, effort, research, and the difficulty in finding some parts, you’ll be lucky if you break even if you try making money off restoring old radios. Fiddling with old radios is sort of a hobby of mine, but to be honest I don’t do it very often because I generally find it more rewarding to spend the time on other things.
There are exceptions, of course. Old amateur radio equipment is one of them. Sometimes. It depends on the condition of the unit (external physical appearance is very important in this market, almost as important as it’s actual functionality), the desirability of the particular brand and model, and, of course, whether or not it works up to its original specifications. I’ve seen some old Collins, Hallicrafters, Hammerlund and the other “legendary” brands of amateur radio equipment being sold for eye-wateringly high prices. But it depends on the model, condition, etc. While at the same time other equipment of the same era, from a lesser known manufacturer, may sell for a fraction of what the popular models sell for, even if electronically speaking the off-brand was superior.
Replacing things like capacitors, resistors and other common components is fairly simple and cheap. You can almost always use easily available modern day equivalents. But things like vacuum tubes can be a serious issue. I don’t think anyone makes vacuum tubes except for a few Chinese and Russian companies, and they only make a very, very small variety of tubes, mostly for amplifiers. There are used ones out there, maybe, and some “new old stock” (NOS) laying around, but they’re getting harder and harder to find, and more expensive. If you can find them at all. Transformers can be a problem too.
Some of these old radios had some serious safety issues as well. I really doubt if some of these old radios would pass modern UL safety standards. So there are liability issues here as well. If a radio you repaired or restored causes a problem later, like someone gets an electric shock from it or a 60 year old component fails and starts a fire, could you be held liable and get sued?
I don’t want to discourage you from dabbling with repairing and restoring old electronics, but I do want you to know that you probably aren’t going to make any money at it, and if you do try to sell the equipment you repair, there could be legal issues as well. It can be a fun hobby but you need to be aware of the potential problems as well.
Apparently Mother Nature wasn’t satisfied with deluging us with snow a month early, now she’s trying to freeze us with temperatures we usually don’t see until well into January. It’s about 3 degrees (F) out there, with windchills down in the -10 range. Sheesh…
Meanwhile, MrsGF has this growing in the living room. Just took these photos the other day-
Yeah, roses. I’ve put up photos of this before, but I figured this plant would go dormant or something by now. But it just keeps right on blooming.
This thing started out as one of those goofy little teacup roses, a tiny plant in a cheap cup that they sell for a few bucks on Mother’s Day or Valentine’s Day. Think I paid all of $7 for it, oh, must be at least two or three years ago. And after we got sick of it sitting around the house MrsGF said what the heck, let’s put it in a big pot and see what happens and the dopey thing just kept growing and flowering. We were putting it in the basement, letting it go dormant over winter, but this year she thought she’d put it in the living room where it could get some light and keep watering it, and well, it apparently likes it there, and it’s been flowering on a regular basis all winter so far.
I asked her how she’s keeping it flowering and she swears she’s just watering it and isn’t doing anything else. Personally I figure witchcraft is involved.
The MagLoop Antenna
I talked about this antenna before, and I continue to be more than pleased with it. Since my dipole came down in the last snowstorm it’s been the main antenna for my TS-990, sitting on the floor behind me in the office. And it is doing ridiculously good.
The Great Radio
I mentioned this before, but let me summarize what I’m trying to do here. For reasons I won’t get into right now, I challenged myself to build, from scratch, a decent radio receiver, preferably shortwave. Emphasis on the word “decent” because I could throw together a few parts and end up with – well, with something that would receive, well, something that might be a radio signal, and pump it into a speaker and you’d hear some sound that might be interpreted as a radio transmission by someone with bad hearing. It could technically be called a radio receiver, but, well, let’s face it, it wouldn’t exactly be useful.
When I first conceived of this project I was like how hard can this be? In those WWII movies the Resistance throws together a radio out of bits of string, a piece of wire, an old cigar box and bits off a horse (don’t ask me what bits, I don’t know, ask them, they built the thing) and call up Churchill at Bomber Command and call in an air strike on Hitler’s outhouse. And the Good Ole Boys in amateur radio weep bitter tears of disappointment over the fact that modern day hams don’t build stuff any more like they did, when they’d throw together a 1,500 watt amplifier, transmitter and superhet receiver in an afternoon, out of parts they salvaged from old washing machines. And bits off a horse for all I know.
Here’s the thing, though – 95% of that (maybe even 98%) is pure BS. I’m sorry, but it just is.
The days of being able to salvage anything useful from discarded electronics are long gone. Modern SMD (surface mount devices) and robotic assembly methods make it virtually impossible to salvage anything useful from relatively modern equipment. And while you can buy discrete components like resistors, capacitors, etc. in the more common values, increasingly it is difficult to find a lot of stuff in anything but SMD form, and in quantities of 1,000 or more. I was trying to find what had once been a very common opamp the other day. It is still available. But if I want to get it from a US supplier I can only buy it in quantities of 1,000 or more, and in SMD format. If I want it in the traditional 6 pin IC form, and only want a few of them, it looks like I’m going to have to order it from China and it won’t get here until mid-March.
Nor are parts cheap. Oh, some are, true, but not the kind of stuff I’m looking for. A single variable capacitor I need for a project sells for $25. And I need two of them. So I’m going to have $50 stuck in that project before I even get started on it.
And then there’s the design of the equipment you want to build. If you were going to set out to build your own radio receiver, probably the first thing you’d do is fire up Google and look for something like “build your own radio” and find, well, hundreds and hundreds of hits that are utterly worthless, along with a few sites that might have actual plans to build something. Only most of those plans are for useless crystal radios and other nonsense. And the designs that do look useful are probably going to be wrong and no one is going to tell you how to fix it when you build it and it doesn’t work. In fact, most of the designs I saw out there were copies of stuff pulled out of old radio or electronics magazines from the 1960s or 70s that didn’t work in the first place.
(Sidenote: I’m convinced that the building plans in all those electronics magazines published in the 50s, 60s, 70s, etc. were never actually built by anyone because about six or eight months after the plans were published there’d be a “corrections” item pointing out that they forgot this part, or the wiring was wrong and if you’d actually build the thing it would have exploded, electrocuted your cat or something.)
So the question is, can I build a decent radio receiver from scratch? Probably. Will it work? Maybe. Can I do it for less than what it would cost to just go buy one? No way in hell. Will it work as good as even a cheap piece of junk commercial radio? Almost certainly not.
So why am I doing this? Uh, because I’m a stubborn old goat?
It’s about 3 AM, I can’t sleep, I’ve been sorting through old photos, so why not post some? I’ve been all over the US on the motorcycle over the last, oh, fifteen years or so, usually with MrsGF but sometimes alone. Here are some of the photos.
Although the temperatures are still ridiculously warm for this time of year, there’s no doubt that autumn is here and the gardening season is winding down and it’s time to look back at what worked, what didn’t, and start making plans for next year.
The tomatoes are pretty much done for the season. We’ll probably still get about 15 lbs or so off the last remaining plants and then we can clean out the raised beds. The tomatoes weren’t as good as I’d really have liked to see, but we still got more than enough to stock our shelves. There was a bit of blossom end rot at the start of the season, but we’d been doing calcium supplementation and that kept it from being a real problem.
The tomatoes all were canned in one way or another this year. We didn’t freeze any because the freezer is packed solid. We did pasta sauce, tomato soup and just plain canned tomatoes for use in things like chili. I didn’t keep track of how many pints and quarts we put up, but it was a hell of a lot. I think we used just about every jar we have. Our big canner can hold 16 pints in a batch, so it really doesn’t take long to do it. I’m writing this as I’m waiting for another batch of 14 pints to finish up.
Those dahlias I picked up for half price in June turned out way, way better than I could have hoped. Amazingly beautiful, long lasting flowers, and they’ve been in perpetual bloom since early July.
That stuff up there inside of those yellow buckets (the bottoms are cut out) is celery. The buckets protect them from critters and makes weed control easy. Works very well indeed and we’ve been growing celery like this for some time. We’ve been cutting celery off those plants since, oh, early August, I think. Cut a few stalks off and it just keeps regrowing. Incredible flavor, too. The thing with commercial celery is that it has little or no flavor. That’s not the case with the home grown stuff. The celery flavor is intense. Very intense. It kind of surprises people who’ve only ever had the commercially grown variety.
I talked before about the mild jalapeno pepper plants I planted in pots on the front porch as an experiment. That worked out beautifully as well. The two plants produced more than enough peppers to keep me satisisfied (I’m the only one who really likes jalapenos so just two plants were enough). And the flavor was very good indeed. They had the right flavor, but very little heat, just what I was looking for. The plants are pretty much done for the season, so I’ll pick the remaining peppers and the plants will go to the compost pile this weekend probably.
Two more successes were the wax beans and the bell peppers. The wax beans are in the front, the peppers behind them. We’d put in a row of green beans, but something ate all of the plants almost as soon as they sprouted, but whatever it was left the wax beans alone. The wax beans more than made up for it though. Great flavor, good texture, and ridiculously prolific. We’ve been picking beans every four or five days since early August and there’s no end in sight, they’re still in full blossom and producing beans.
The bell peppers seem to always do good in this location. We’ve been getting absolutely beautiful peppers off the plants this year. They’ve been well formed, growing to almost ridiculously large sizes, thick walls, firm texture, good flavor. A lot get eaten fresh but we’ve been dicing up and freezing some as well.
Not everything was successful, though. We aren’t going to get any pears off our tree this year. The tree looks nice and healthy, but almost no fruit. The problem was the weather. When the tree was in full blossom the weather was still ridiculously cold and wet, so it didn’t get pollinated. In fact, I didn’t even start to see bees until two or three weeks after the three blossomed. Earlier in the year I counted about 20 or so pears on the entire tree. There are maybe fifteen up there now, and I saw today that something is eating them while they’re still on the tree. Birds, probably.
The other disappointment is the squash. It started out well but went nowhere fast. Only one plants looks reasonably healthy, but it’s much smaller than it should be and only has a couple of gourds on it. The other plants are much worse, with a few very undersized gourds that will probably end up in the compost. We get lots of blossoms, but very little fruit. I think this is the last year we’re going to try growing squash. It just doesn’t work out for us.
We need to start doing garden clean up much earlier than we normally wood. MrsGF is going in for knee replacement surgery in early October so we want to have everything done that we possibly can before then because after that, well, trying to get anything done outside is going to be awkward because I’m not going to want to leave her alone in the house with a bum leg while I’m out puttering in the gardens.
We’re already talking about putting in a third and maybe even a fourth raised bed for vegetables next spring. They just work amazingly well and are so much easier to take care of than a regular garden plot would be. We’ll probably keep putting veggies in the corner where the beans and peppers are, but the rest of our yard? The soil is so poor and gets so water logged in rainy conditions that it’s difficult, even impossible to grow much of anything except ornamentals.
That’s it for now. Time to pull the jars out of the canner and start cleaning things up.
Let’s see, what else? I’m putting together an evaluation of a new transceiver I just picked up a couple of weeks ago, a Yaesu FT-450D. I hear so many people complaining about how expensive amateur radio is that I wanted to do an article proving that it really isn’t anywhere near as expensive as people think it is, and the 450 is at the core of that piece.
Moving all my equipment to the new location in the basement is about half done, but is now on hold because of MrsGF’s upcoming surgery. I can’t be hiding down in the basement while she’s recovering from knee replacement, so I’m going to be leaving the big equipment up here so I have something to play with while keeping an eye on her and making sure she isn’t trying to do something she shouldn’t. I know her, and I know damn well that she’s going to try pushing things too far, too fast.
And here’s a picture of a cat. Just because.
Let’s start out with this —
I’d just got back from an early morning bike ride, about, oh, 6:30 or 7 AM, and the sun was just hitting the gardens in the backyard when I snapped this one with the iPhone. The colors were so intense it looked like it was glowing. I absolutely love those ‘dinner plate’ dahlias. It’s always worth taking a look for things on sale after the spring planting rush is over. I picked these up for half the price they were at the start of the spring season.
When I was farming, thistles were a noxious weed that needed to be controlled. Now I think they’re one of the prettiest looking plants we have. Just look at those flowers. The structure, the color, everything about them is just stunning.
Then there are these goofy things – MrsGF cleaned out the flower beds along the south side of the garage the other week, taking almost everything out, and a few days later we noticed what looked like small asparagus stalks poking up through the soil. The weirdest looking things, just slender stalks with a bulbous end and the nastiest color you could think of. Sort of looked like zombie asparagus. Then we remembered these things had popped up a few years ago and surprised the heck out of us then. We didn’t plant these and we have no idea where they came from, but holy cow the flowers are stunning!
People sometimes ask us why we have huge sunflowers growing along the side of the house. Here’s why –
Goldfinches absolutely love these things and they swarm them as the flowers begin to fade and the seeds begin to develop. They are an absolute riot to watch, squabbling and leaping around, flitting around, hanging from the plants upside down like little acrobats. They don’t seem to notice that we’re standing on the other side of the window watching them. We’ll have a dozen or more of the little goofs working over the flowers at one time this time of year.
This is the time of year when all the work we put in on the gardens really begins to pay off. The bell peppers are beautiful this year. We have ’em tucked into a corner facing the south and west where the garage is built onto the house and they love it there. It’s warm and sunny and as long as we remember to keep them well watered they (and the wax beans planted near them) have been thriving. We go through a lot of sweet bell peppers around here. Everyone loves them. Most will end up diced and frozen, but we eat a lot of them fresh in salads, ingredients in sauces, stir fry, etc.
Youngest Son and I had nothing else to do Saturday so we went to the Manitowoc county fair. Both of us don’t care about rides or that stuff, we’re more interested in A) weird food, and B) the exhibits. I get ridiculous sense of satisfaction to see how much better my produce and flowers look than the prize winners do. Petty of me, true, but it’s still satisfying.
Anyway, goats have become a big thing around here in the last ten or fifteen years. You almost never would see goats around here before then. Now there are more goat exhibitors than than sheep and pigs. I have to admit they’re fun. They’re charming and curious and don’t seem afraid of anything, and they all seem to have this ridiculous, goofy attitude about them.
For a while llamas and then alpacas were “the next big thing” that were going to make people tons of money. They didn’t, of course. None of these fads ever pan out. We’ve gone through bison, emu, llamas, alpacas and elk as “the next big thing” since, oh, the 1980s. (Emus are nasty. Think of a giant chicken, taller than you are, with a bad attitude. An emu would gleefully kill you and dance on your corpse if it thought it could get away with it.) There are still people in some parts of the state who think emus are going to be financially successful if only they could get a foot in the door with their emu products. You’ll still find gas stations and farmers markets where people are trying to sell emu jerky (shudder), emu oil which is useful for – well, hell, I don’t know what the hell emu oil is good for. Lubricating emus? Emu meat (tastes like chicken?) and I don’t know what all else.
Eldest son and his girlfriend took a short vacation way up along Lake Superior where the air is clear and there are no lights, and asked if they could take the big 11″ Celestron telescope along. I was glad to let them have it. The poor thing has been sitting under its cover in the closet for an embarrassingly long time. I love the scope but the thing is huge and heavy (the tube assembly weighs around 60 lbs). It’s almost impossible for me to lug it up and down the stairs and maneuver it through the doors to get it outside. And when I do get it outside the air quality here has gotten so bad and we now have so much light pollution from streetlights, houses and businesses that it hardly pays to even bother taking it out at all.
Anyway he sent me a text message telling me the scope has been working very well and he sent along the photo above. Very glad they like it. I hated seeing it sit unused. I was thinking of donating it to the school district I used to work at for their new STEM center. That’s what I did with my big camera drone when I got tired of playing with it. If ES is having fun with it, he’s more than welcome to keep it. Otherwise I may donate it to the science program at the high school.
And that’s about it for this time.
