Hey, I’m bored, so how about a few before/after pics?
I don’t have a ‘before’ photo of the squash for some reason. They’re looking great right now. They’ve just about tripled in size in the last week. The squash didn’t do well last year. They got powdery mildew which pretty much decimated them. But so far so good this year.
I had to throw in a photo of Mr. Spiny, our cactus because it just flowered yesterday and, well, look at that thing! Mr. Spiny is our “rescue cactus”. We found it laying on the town compost pile a few years ago. It had been a potted plant probably in someone’s house. We stuck him in the ground in a south west corner of the house, and he apparently loves it here.
I finally got the motorcycle out the other day. It had been sitting parked in front of the car for ages. Had to get a new battery for it and it started right up so I ran it around town for a while. MrsGF and I used to really be into motorcycling, especially long distance touring. We used to have a BMW that we spent weeks on every summer. Then we traded that off on a Goldwing. But around that time she started having problems with her knees and it was really hard for her to get on and off the bike, and well, we put a whopping 5,000 miles on the Goldwing in three years so it didn’t make sense to keep it. So I worked out a trade with my son and he’s got the Goldwing now and I have this VTX to run around on when the urge strikes me.
That’s the BMW we traveled on. We put about 50,000 miles on that thing traveling from Maine to Montana. Loved that bike. I suspect that if BMW hadn’t discontinued that model we’d still have one.
If this time of year could be described by a single word, it would probably be “color”.
Almost everything is in full flower this time of year except for the autumn flowering plants. Just walking outside is a feast for the eyes.
So, let’s get caught up on what’s been going on. I haven’t talked about it much but one of the things I do is build furniture like, well, like this:
It looks a bit beat up now, especially the upholstery, but considering it’s lived through two teenaged boys, a rambunctious golden retriever and several assorted cats, it’s doing pretty good. Over the years I’ve built chairs, coffee tables, wardrobes, bookcases, decorative chests and I don’t know what all else. A few years ago one of my sons gave me a cheap wood lathe from Harbor Freight and I finally started fiddling around with it. It was super cheap and to be honest the build quality isn’t exactly what I’d call good. But I’ve messed around with it a bit, bought a decent set of tools for it and I’m going to see if I can add woodturning to my skill set. We’ll see how that goes. I’ll let you know if anything comes of it.
We’ve been spending a lot of time out in the gardens, of course. Where else would we be this time of year and with the pandemic still raging? Gardening is probably the safest and most satisfying activity we can do right now. But we’re still dabbling in radio. And I mean “we”. MrsGF is a licensed amateur radio operator as well. She’s more into the emergency services aspect of it while I’m more into the technical stuff.
It looks like the Great Radio Fiasco Project is back on the agenda. I was finally able to get the toroids I needed to wind the coils I need. But considering how busy we are with other things this time of year it’s likely that will be pushed back until the fall.
Let’s see, what else… Oh, I’m working on an upcoming post that answers some questions about amateur radio that people have asked. That will be coming up in the near future.
I’ve been working on getting better at CW (morse code). I’m still struggling, especially with receiving. I’m nowhere near good enough to be able to actually use it out in the field. If someone sends at like, oh, one word per minute or slower, I can generally figure it out. But any faster than that and everything sort of blurs together and I start to fall so far behind I have to give up.
Someone asked me if I was going to do anything for the ARRL Field Day exercise. Nope. Don’t have the time. This is probably the worst time of year for me to try to participate in an event like that.
We’re going to be doing some major renovations to the house this summer, replacing a bunch of windows, the front entrance and some other stuff. That’s going to be a mess, but it needs to get done. And expensive. Sigh… Oh, well. Owning a house is great. Until you start seeing the bills for maintaining it.
Wisconsin is known as a place of snow and cold and rain and giant blood sucking insects big enough to carry away small pets. Oh, and heat and humidity that occasionally rivals Florida at its worst. And tornadoes. Pretty much we get all the bad weather concentrated in this state. Well, at least we don’t have rattlesnakes. Yet. Anyway, the weather has finally gotten better and stuff is growing and we’ve been out in the gardens here for days already. So I was out taking some pictures as I puttered around in the garden.
Not the best picture in the world but I was using my phone because I was too lazy to go in the house and get the camera. This is the “Zombie Rose”. This thing has been there since before we bought the house. We thought it was dead more than once and only laziness on my part kept me from digging it out. And then a few years ago something happened, we don’t know what, and it turned into this ridiculously healthy bush that’s covered with flowers by mid summer and blooms the entire season.
The hostas are looking amazing this spring. All of them in the front hosta garden survived the winter and they’re growing so fast you can almost see them getting bigger. Best thing we did was rip out the ratty grass and old bushes and junk up in front of the house and put this garden in.
winter didn’t hurt the mountain ash tree we put up in the corner of the hosta garden either. We forgot to put screening around it to keep the rabbits out but fortunately the little buggers left it alone. It’s actually a member of the rose family.
Wish I could remember what in the world these little blue flowers are. MrsGF told me once and I immediately forgot, of course. They’re pretty little things. Those flowers are only about 1/8th of an inch across so you have to get down there to really see them.
The pear tree is in full flower and looking very good. Last year it didn’t get pollinated because the weather was so bad we didn’t have any bees around. This year things are looking much better. I haven’t seen any honey bees around but I have been seeing a lot of native bees buzzing around it so hopefully we’ll get some pears this year.
They say you can tell how healthy your environment is by the number of amphibians living in the area. If that’s true, our gardens must be pretty damned healthy because these little guys are everywhere. I have to be careful mowing the lawn and stop a couple of dozen times to move the little critters out of the way. I’ve spotted about four different types of frog and at least one type of toad in the backyard this year. Go outside on a warmish evening and the number of frogs calling and singing is amazing.
And the lilacs are just starting to flower. In a couple of days these buds will start to open and it will smell amazing. A lot of people have lilacs around here and in early spring when they’re all in blossom you can smell them all over town.
Let’s see, what else… We’ll be putting out the tomatoes and pepper plants over the next few days. But we scaled back the amount of vegetables we’re putting in because we generally go way, way overboard with this stuff and end up with a lot of produce we can’t use. We still have almost enough canned tomato stuff on the shelf from last year to last us the rest of this year. We know we over plant but, well, MrsGF and I are both the kind of people who see a bit of bare ground and go “Hm, now what could be plant in there…”
The storm window on the office blew out during a storm. The main window is okay so it wasn’t an emergency, but we found that the outer frame of the window holding the storm window in place was almost completely rotted away. The only thing holding it in had been the paint apparently. So we’re getting some new windows for the office and a new front entry door while we’re at it. Contractor was over on Monday to take measurements and get an estimate put together.
Haven’t had much time to tinker with amateur radio stuff. I almost always have the rig on 40 meters with the computer running JS8Call doing ACKs and stuff like that when I’m down in the shop/radio shack, but I’m generally just monitoring things unless someone specifically calls me. I did try doing some morse code last night but didn’t get very far. I was showing up on the reverse beacon network but didn’t get any replies to a CQ. Well, maybe because I only did one CQ and then got distracted because I found a new soap opera on Youtube… Anyway that was probably not a bad thing because I’ve been told that a drunken chicken pecking at the key sends CW better than I do. Which is probably true, I fear.
Speaking of soap operas – I am embarrassed to admit it but I am addicted to Chinese romcoms, or dramadies or whatever you want to call ’em. I thought Korean romcoms were often ridiculously silly, but the Chinese versions are just over the top. They’re formulaic, generally all following similar plots, with cliche actions taking place that seem to be required for some reason. Some of the better ones embrace the cliches whole heartedly and basically satirize themselves and gently poke fun of the whole genre. And at the same time the whole thing is surrounded in extreme sexism and actions that would be considered outright abuse and criminal outside of the television environment. They’re silly, charming, innocent, dark, infuriating, irritating, funny, horrifying and hilarious. Often all at the same time.
One of these days I should write something about Chinese television. It is – different.
We all need a break from the non-stop news coverage so I’m declaring this a virus (and politics) free zone. It’s spring, or at least the calendar says it is, so it’s time for some photos of what’s going on out in the gardens.
If you’re like me, you’re ready to scream because of the 24/7 fear, panic and everything else you’re seeing on the news and internet. So here’s some photos to distract you. Well, if my internet connection stays up, that is. It’s been down a half dozen times already today.
That’s enough for now. I’m pushing my luck with my internet connection here, I think. It went down three times while I was uploading photos.
MrsGF and I were coming back from her sister’s place and we saw this. The photos don’t do it justice. That sunset almost looked like an atomic bomb going off, lighting up the whole horizon with that single shaft of light extending up. We had to pull off and just stare at it for a while because we’d never seen anything like it before.
Sunsets and sunrises (when we can see them, usually the cloud cover is too thick) have been spectacular of late. I imagine that’s due at least in part to so much particulate matter being in the atmosphere at the moment because of all of the forest fires we’ve been having worldwide.
As far as the weather goes, well, it’s winter, and we have some snow, as you can see from the photos, but it has been, well, weird. Just like 2019 was. Temperatures have been well above normal this winter. So much so that the ice fishermen have been getting nervous because they can’t get out on the lakes. This late in the season the lakes and rivers should have enough ice that you can at least walk out on the ice, and in some cases even drive a vehicle out. But you couldn’t pay me enough money to make me risk walking out on the ice this year. Most of the rivers and streams are still mostly open with almost no ice at all.
Ice fishing is a Big Deal around here. Generally as soon as we get a couple of inches of ice on a lake you’ll see little huts springing up or guys in cold weather gear huddling over holes drilled in the ice hunting for elusive panfish like bluegills and crappies. They endure it because one, they think it’s fun, and two, well, if you’ve ever eaten a freshly caught pan fried bluegill or perch, you know why they do it.
But The big event around here in mid winter is sturgeon season on Lake Winnebago. During sturgeon season there are thousands of people out on that lake, with hundreds of cars, 4 wheelers and snowmobiles, hundreds of ice shanties full of people huddling over holes in the ice hoping to get themselves one of the biggest fish you can get in Wisconsin. These things get to be five, six feet long or even bigger, and can be well over a hundred years old.
But we need ice for that, and we don’t have any. Or at least not enough ice that you can trust it. Unless we get a cold snap that really freezes things up, I’m not sure if there is going to be much of a sturgeon season this year.
While it may be winter outside, MrsGF’s rose in the living room is blossoming again.
I have no idea how she does it, but I’m not complaining. Having roses growing here in the middle of January is huge fun.
The Great Radio Fiasco ProjectUpdate
Considering I’m lazy and about the most unambitious person around, I bet you figured I’d sort of conveniently “forgot” about that whole thing, didn’t you? Ha! I wish! Sometimes I’m more stubborn than lazy, though, and when I get a bug about something I get a bit obsessed, and that’s what happened here.
Anyway, that hasn’t been going very well because of stuff like this –
One of the first things I discovered when I started doing some research was that I pretty much had none of the parts I was going to need. I may have had hundreds of diodes, capacitors, resistors, potentiometers, transistors and other goodies sitting on the shelf from other projects, but it seemed that none of them were what I needed for building any kind of radio receiver except for the most basic of items. So once I decided more or less on what kind of radio I was going to build, I had to order some parts. And as you can see above, sometimes it doesn’t go so well.
The main project is going to be a multi-band shortwave receiver, but I was also going to build an old fashion 1960s style AM transistor radio which uses a ferrite rod wound with wire as an antenna. What you see in that photo above is what was in the package when I opened it. Sigh… Don’t get me wrong, though. I order a lot of parts, and the vast majority of the stuff gets here in perfect condition. But every once in a while something like this happens, and all you can do is just sigh and go on. It doesn’t pay to try to do anything about this in this case. I only paid about $10 for them, the company is in China, and any chance of getting a refund or replacement is so slim it’s not worth the effort. On the plus side one of the rods is relatively undamaged with just a chip on the end, so it will work well enough for the AM radio.
But it does help to illustrate one of the problems I’ve been having, which is tracking down various parts. The days of being able to go to a local electronics or radio repair shop, or even Radio Shack, and picking up a couple of capacitors or an opamp or whatever are long gone. While I still do have a local Radio Shack (how I don’t know, but I do), it only carries the most common types of components, and I already got those by the dozens.
I need a germanium diode for one radio circuit I’ve been tinkering with. Do I have one in those boxes on the shelf with hundreds and hundreds of diodes? Of course not! The one I need is the one I don’t have, of course. And, well, you generally can’t order just one. So I ended up spending something like $15 to buy 50 of the dopey things. It’s like the robot vacuum cleaner I repaired a few years ago. I needed one tiny, tiny screw that held on the side sweeper brush. That was all that was left to fix it, just attach that stupid brush. Do you think I could find that damned screw? No. No one locally had it. I checked hardware stores, Radio Shack, auto parts stores, no one had one even close. I started looking online and found I wasn’t the only one having trouble find it. I finally did get one, but in the end the only sources I found for it sold them only in lots of 500. So I ended up paying something like $25 to get a single screw, and I now have a whole bag full of 499 tiny, tiny screws sitting in a closet somewhere that I’ll never use for anything else.
The same thing is often true of electronic components. You can’t get just one or two, you have to buy in bulk sometimes, and you end up paying $25 or $40 for a whole box of parts just to get one $0.75 component. The end result is that while the cost of the individual parts for this project is pretty cheap, I’ve ended up spending a significant chunk of money on this already because I often can’t get just one or two, but have to order in bulk.
But enough with boring you with that. Once I get further along with the radio thing I’m going to split it off to its own web page so it doesn’t clutter up the blog.
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 Fiasco Project
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?
