When I started moving my stuff from the office upstairs to the new workspace in the basement I knew I was in trouble when I plugged in the laser printer, turned it on, and the lights all went dim. So the electrical contractor got here at 6:50 AM the other morning and some two hours later I had the radio shack/shop rewired with new circuits and outlets. The electrical in this space was a bit scary. I think the whole room was connected to a single 15 amp circuit. I was running my radios and other equipment off heavy duty extension cords running into my woodshop and, well, it was just nasty all the way around. The grand total for all of the work and parts ran about $500 but it’s going to be worth it, for safety alone if not for convenience.
So now I have two, 4 outlet 120V boxes, each on its own circuit, plus a 220V outlet over on the radio bench, and two new 120V circuits for the workbench.
Why call in a contractor instead of doing it myself? Because I know where my areas of competence are. I worked on a farm and in building maintenance for years and I can do just about anything – framing, finish carpentry, drywall, installing doors, plumbing, laying tile… But electrical? I’ve had no training or experience in doing household electrical, and considering how dangerous it can be, well I’m going to let a trained electrician do that.
Tubes & Stuff
So eldest son shot me a text Friday asking me if I wanted a vacuum tube tester, free, and I texted back “r u nuts? yeah i want toob thingie!” or something to that effect and he showed up last weekend with this:
The thing with free equipment is that it’s often going to be something useful only for parts, if that, but in this case it turned out to be a genuine, working vacuum tube tester. Oh, it has a few issues. The tube sockets have some corrosion that needs to be cleaned up and it could use a good cleaning in general. The insulation on the cords is brittle so they need to be replaced, but other than that the thing actually seems to work and inside it actually looks almost new.
I haven’t done much with equipment with vacuum tubes of late, but I never know what’s going to show up around here, so this could come in handy.
Tinkering with Stuff
I am building a radio receiver. No, not The Great Radio
Fiasco Project. That project is more or less on hold until I can get some parts that seem to have become unobtanium for some reason. I may end up having to change the design. No, this is an Elenco AM/FM receiver kit. Best of all it was free! Well, maybe it was? I found it in a box of junk I was sorting through as I continued the apparently never ending project of cleaning out the basement.
I don’t remember ever buying this thing and have no idea where it came from, but it’s in my basement, in my box, so I’m assuming it’s mine, so I’m going to put the thing together and see what happens. It’s a fairly elaborate little radio and from time to time the instructions seem to go wandering off into fantasy land. I suspect that the instructions that were in the box were written before the circuit board was changed and no one bothered to correct the instructions. So that makes things a bit interesting.
Also in the same box of junk I ran across an unopened multiband shortwave receiver kit distributed by MFJ. I don’t remember ever buying that either, and I would remember since that one costs about $80 and I darn well wouldn’t have spent that much. I suspect both were in a boxes full of “valuable assorted radio parts” (i.e. junk) I picked up for next to nothing at a hamfest, and the box just got shoved on a shelf and forgotten about before I bothered to sort through it.
Over the weekend it hit 50 degrees. Almost all the snow melted, motorcycles were out on the streets, a very pleasant weekend all around. Tomorrow it’s supposed to hit 55 degrees!
So, of course, today it snowed. Sigh… I know Wisconsin in known for having some odd weather, but this is ridiculous.
I am sure you heard about covid-19. You’d have to have been living in a cave on Mars to not have heard. Wisconsin has only 6 confirmed cases, but the potential of it spreading, and spreading quickly, has everyone concerned. At least one school district has closed, the UW system is extending spring break and advising students not to travel, companies are canceling employee travel. The state basketball tournaments are starting up this week and WIAA just announced that general spectators will not be allowed, only the teams and necessary personnel and a small pool of sports reporters will be permitted.
I want to think a lot of this is hype and paranoia, but, well, I’m right smack dab in the middle of the category of the highest risk for death if I catch this sucker, so yeah, I’m a wee bit paranoid. MrsGF and I are supposed to go to the symphony this weekend, but sitting elbow to elbow in a theater full of hundreds of coughing, sneezing, hacking people for two hours? Uh, no.
What I really find troubling is the huge amount of misinformation being spread, some of it through ignorance, but a lot of it being spread deliberately. Some of it by our own government. I wasn’t going to spend a lot of time talking about this because, well, let’s face it I don’t have that many people who read this so it isn’t going to make a dent in things, but if it helps correct some of the stuff floating around, I suppose I should go into this a bit.
First, there is no cure for covid-19. None. Zip. Zilch. Zero. There is no drug, no “natural remedy”, no combination of herbs, no “silver” concoction. None. If anyone is trying to sell you such a thing, it is an outright scam.
Second, there is no magic herb or substance or “essential oil” or vitamin or magic crystal or “holy oil” that will somehow keep you from catching the virus. Again, if anyone tries to sell you such a thing, it is an outright scam.
Third, there is no vaccine “just around the corner”. Yes, a vaccine is being worked on and there are some promising candidates. But it will be months before one is generally available and even longer before it can be mass produced.
So what can you do?
Wash your hands. A lot. The best preventative is hand washing. Wash your hands using soap and running water. This doesn’t kill the virus, but it does physically remove it from your hands, which is just as good. Do not touch your face except immediately after you’ve washed your hands. A primary method of getting the virus into your system is touching your eyes, nose or mouth.
Do hand sanitizers work? Yes, but only if they’re the right kind. They have to have at least 60% alcohol content. Non alcohol based sanitizers are out there, but no one knows if they actually work or not. The so-called “all natural” hand sanitizers don’t work at all. They’re little more than hand lotion.
Face masks – there is a lot of debate about whether they work or not, and the consensus is that they don’t do much to keep you from getting the virus. They can prevent people who already have it from contaminating others, it seems. The problem, though, is that most of the masks I’ve seen people wearing are dust masks intended to keep dust from getting into your lungs, and were never intended to keep out viruses to begin with. Most people also don’t know how to wear them properly. Heck, I’ve seen a lot of people who have them pulled down to expose the nose. If you do that you might as well not bother at all. Same for guys with beards. If you have a beard, don’t bother. If you can’t seal the mask against bare skin, it isn’t going to work at all.
Social Distancing – what the hell is social distancing? It’s a polite term for keeping the hell away from people. Do not shake hands, do not hug, do not kiss people. Try to keep at least one meter (three feet) away from people if you do have to interact with them.
Avoid crowds. Do not attend sporting events, concerts, meetings or other events where large numbers of people have gathered. I don’t know about where you live, but here most such events have been canceled or postponed anyway. (Although a seriously troubling number have not and are still scheduled). And yes, that goes for church services too. No, being in a church is not going to somehow protect you from getting the virus despite what some utterly irresponsible ministers and priests have been saying. Remember that the primary spreaders of the virus in South Korea when the outbreak first began there were churches. Even the Pope canceled most of his public appearances for heaven’s sake. And if you’ve booked a cruise on a
plague ship (ahem, excuse me) cruise ship, well, you’re on your own.
If you’re sick, stay home. About 80% of the people who get it have symptoms that are relatively mild and a lot of people will be tempted to continue with their normal daily routine. And thus risk spreading this to even more people. I realize this is damn near impossible for a lot of people, but the primary way this is spread is by people with relatively mild cases going out in public. Do you really want to be responsible for infecting your friends, your family and your neighbors with this?
Anyway, enough of this. I’ve been babbling long enough.

Cincinnati has no confirmed cases but declared a state of emergency. I guess it is so they can access funds etc without legislation. It feels like they shouldn’t call it a state of emergency.
Maybe a state of preparedness. Still, I wonder how many people have it but haven’t been tested.
I know what you mean. It does seem like they’re going overboard, but when you look at how fast this spread in China, Italy and South Korea, they have to do something to try to contain it. About the only thing they can do is try to keep people from spreading it.
I’m sure a lot of people have it and don’t know it. For most people the symptoms are fairly mild and a lot of people are going to just try to ignore it and go on as usual. Those are the ones who are going to be the real problem, the ones who try to tough it out and end up exposing everyone they meet

I once built one of those Elenco kits too! It’s not a very good design and I never got it to work exactly right, but it was a fun experience.
I found out exactly what you mean. It does have some problems. Half the transistors were missing, but that wasn’t a big deal because they’re a pretty common type and I had them on the shelf. But there were three capacitors left over on the card of parts and for the life of me I can’t figure out what they were supposed to be for. Maybe for a different kit? Not listed in the instructions and there’s no space for them on the CB. I did all of the recommended intermediate testing and alignment at the end of each section and that all worked, but once I had everything together, that was a different story. The AM side doesn’t seem to receive anything, but at least it makes a hissing noise which is more than the FM side will do. I’m going to have to go back over the whole thing and see if I messed up somewhere.
The other kit is an MFJ regenerative shortwave receiver. Much, much simpler, but that’s got some issues, too. No instructions at all in the box, just a sheet sending me to a website to download a PDF which isn’t actually the assembly manual but a generic manual about how to use a regenerative receiver, and a PDF of the schematic which was so low resolution that all labels were blurred out. I finally did find the manual by running a search on Google and it turned up a copy buried somewhere on MFJ’s website. But come on, really? They couldn’t even get the address for the manual right? That’s not really encouraging.
When I was scrounging around MFJ I found the kit itself and saw it’s going for an utterly ridiculous $80. There’s like maybe $15 worth of parts in the whole kit, for heaven’s sake. Although the case is really, really nice. Heavy steel with a nice faceplate.
