I like Frank Harris K0IYE's book so much that I don't mind posting about it frequently. "From Crystal Sets to Sideband" is must-read material for all homebrewers.
The picture above is especially significant. I first came across it in the old pulp-style magazine called World Radio. The picture, like Frank's book, is truly inspiring.
This week I stumbled across a relatively new chapter in Frank's book. Chapter 3A deals with his approach to homebrewing (Luddite, analog, HDR) and his advice on how to set up a home ham-radio workshop. There is a lot of wisdom in this chapter.
The opening paragraph of Chapter 3A really grabbed me. Check it out here. Click on the text below for a better view:

Frank's advice on what to do when you get stuck on a problem is right on the mark, and a bit counterintuitive, but very true: Do something else for a while.
My fellow Hambassador Dave WA1LBP sent this to me today (from Taiwan, I think). Lots of great ham radio and SWL info in these many publications. The one that caught my eye was "The Modulator," an ARRL publication done by the 2nd District in the 1920s. Really interesting. I will sent this to Lyle, W7QCU who has an interest in radio from this era.
Joe KA1BWO is a well-known AM operator who moved West to Idaho several years ago. We had a very nice contact on 10 meter AM on January 14, 2024. See the video above.
I was using an old CB rig that I had converted to legitimacy on 10 meters using the mod developed by Jerry K5JC:
Lots of great ideas on workshop or lab design from Andreas, the guy with the Swiss accent. Andreas is HB9BLA. I liked all of this, especially his idea on books.
This contact with Masa was a lot of fun. 2300Z January 14, 2024. 15 meters was obviously in great shape. Suddenly I started hearing clock chimes. The sound seemed to be coming from my rig. Then I looked at my watch and realized we were at the top of the hour. Masa-san's clock chimes were being picked up by his microphone. The microphone was in his I-pad, which he was using to connect to his ham radio station. Very cool.
This email came in from Masa:

to me
Hello Bill
Thank you very very much for your Email attached the video of our QSO.
Your homemade transceiver is working excellent! I was very surprised to watch the video. I checked transmitting of your equipment is very good this morning. And this evening I understood receiving was also very very good. Congratulations on your homemade equipment.
I have tried remote operation for several months. But I’m afraid my transmitting is not good.
Thanks for your video, I could tell following things. Thank you so much l appreciate it.
My remote signal has almost no blinking up,I felt.
There are about 2 seconds latency on my transmitting.
Most important thing I realize is English conversation over the phone is very difficult for me. I need to learn intonation and pronunciation of English much more.
Again thank you very much for your Email,I appreciate it.
For years I have been heartlessly slaughtering innocent Heathkit Q multipliers, just to get these variable capacitors. Dean KK4DAS has joined me in this mayhem. And recently Wes W4JYK has also started hunting down QF-1s.
I am sorry to report that my love for this variable capacitor has taken a hit. The capacitance is perfect. And it has a reduction drive built into the shaft. But I have found that that reduction Drive has a form of backlash. It is really just a dead spot that you find when tuning in a signal. Turning in one direction, all is good. But when you then try to turn in the other direction, you have to turn the shaft a bit before the cap blades begins to move (see video above). This makes tuning SSB signals a bit difficult.
What should I do? Should I pull out a Dremel and cut off the reduction drive, then use a better (external) reduction drive to move the vanes? Any other ideas?
These are the kinds of problems that homebrewers face...
Wow, this is something that I've wanted to fix for a long time. I wanted to make it possible to display subtitles in many languages on my YouTube videos. Andreas Spiess (the guy with the Swiss accent) just showed me how to do it. YouTube never really explained this very well. But Andreas did. This is how it works:
I just tell YouTube to display English language subtitles. People can watch these English subtitles, or turn them off. But here is the cool part: People who want to see the subtitles in a language other than English, just go to AutoGenerate Subtitles, and select the language they want. Apparently YouTube just has an AI translate to the target language from the original English transcript. BOOM! Roberto es tu tio!
Here is what you have to do:
1) After you turn on the video, go to Subtitles/CC and turn it on.
2) Click on English (auto translate)
3) Then click on the arrow and select the language you want to see the subtitles in.
Once you do this and select your language, all you will have to do in future viewing sessions is to hit the CC button on the YouTube video toolbar. Subtitles in your language should then appear.
You may have to play with this a bit, but it works, and this should make a big difference for many viewers. If you run into trouble, watch Andreas's video (above) or send me an e-mail.
I need to go through all of my videos and set the original language to English. For some reason YouTube had it set to Azerbaijani. I don't know why, but I will --starting from the most recent -- go back and change the original language of the videos to English. I have changed the settings so that all future videos should generate the English subtitles automatically.
I tested the mechanism in Spanish and in Urdu. It works. Below you can see the Urdu subtitles on a recent video:
Hi Bill, Given that the audience of SolderSmoke is more angled towards home brew and self construction, I wonder if you would mind informing your listeners of a very valuable antenna design website that despite the high level of quality work put in, is not getting very many visitors and may therefore be taken down.
Access to the site is free and the URL is sota-antennas.com.
Despite SOTA being part of the name this is of use for all portable operators and indeed home stations as well. It is a series of online tools that not only defines wire lengths for building but also gives EZ-NEC like diagrams of the expected radiation patterns. My favourite little jewel is in the off-centre-fed dipole section where the positioning of the feed-point is varied automatically to show you the bands the antenna will resonate on. So as an Example a 40m OCFD with a feed-point at 33/66% will not resonate on 15m however one with the feed-point located somewhere near 18/82% will.
The website currently supports Linked-Dipoles, Off Centre Fed Dipoles, End Fed Half Waves, Delta Loops, Half Squares and Moxon antennas. It could be extended to support others but that is unlikely if the current site is not used more.
I think we got our first e-mail from Ramakrishnan way back in 2006. At the time he was VU3RDD. On June 22, 2008 in SolderSmoke #86 we reported on the birth of Ramakrishnan's new harmonic. In this interview with Eric 4Z1UG we hear of Ramakrishnan's daughter (the same harmonic) getting her ham license and working with her dad on electronic projects. Ramakrishnan has been with us for a long time!
It was very cool to hear Ramakrishnan talk about the Lamakaan convention, the BITX 40, and the book The Electronics of Radio. There was a nice mention of SolderSmoke and Pete.
As you know, here at SolderSmoke East HQ we are all about TRADITION. So last night (New Year's eve) I fired up my venerable HT-37 / Drake 2-B combo and made a few Straight Key Night (SKN) contacts on 40 meter CW. I was indeed using my straight key. Video above.
"SolderSmoke -- Global Adventures in Wireless Electronics" is now available as an e-book for Amazon's Kindle.
