KW4H -- Steve -- "Knobs > Menus"
I really like the "KNOBS are greater than MENUS" sign. For years we have been saying that menus are for restaurants. FB Steve.
Steve's resotation man-cave is very interesting, as are the rigs he has on the shelf or on the bench. Lots of good work is obviously being done there.
I also have one of those KP4USA QSL cards. Steve and I got into ham radio at around the same time, so it is possible that he was on the other end of that QSO. I will check.

Fixing up a Nice Old (but not TOO old) Receiver in the UK -- What would you have done? Please comment below.
Crikey! Blimey! The parts are wonky! Then he fixes it and they are all lovely! These are some great descriptive words that you just won't hear in a U.S. workshop. Pity.
I liked the receiver. I had never seen one of these.
The Ultrasonic cleaner was nice. As was the oven.
His repair of the switches was very cool. I like his technique for repairing the many leads that got broken.
When he started unplugging the plugs on the boards, I got nervous. Pull out the cell phone and take some pictures first!
Opening up those old pots was really going the extra mile. I would have just squirted some deoxit in them.
He ended up changing almost all the caps on the AF amplifier board. The Capacitor Police would indeed been annoyed.
Great job. It was fun watching him work. But what would you guys have done differently? Please comment below.
Thanks to Rogier PA1ZZ for sending me this.

Vintage Audio Restoration: Glue, Fusible Resistors, and Relays
This guy is restoring VINTAGE audio gear. It is definitely younger than the Boatanchors we usually work on, but it is a lot older than more recent gear that is made with largely pick-and-place machines and surface mount components. There are mostly through hole components here.
There are some challenges I've never thought about: glue that over time starts to mess up the circuitry. Fusible resistors? Who knew? And then there are relay contacts that go really bad. We use a lot of these kinds of relays.
All in all, there are a lot of good ideas in this video. His other videos are probably worth watching too. I think it will be especially useful for my friend Bob, KD4EBM who does a lot of work in this area.
Please let me know what you think. Comment below.

The Snake Shack of the Amazon
https://www.nytimes.com/2026/05/29/science/snake-collector-mera-ecuador.html?unlocked_article_code=1.o1A.2O0_.gzrRsoBWgWvH&smid=url-share
Think of this as part of our "other kinds of workshops" series. In this case, it is literally another kind of shack.
The article describes an understandable cultural message that says snakes must be killed. Like the people in this story, we have to fight against similar cultural issues in the Dominican Republic.
Anyway, I liked the story. I hope the link survives.

Solar Powered Drone from South Africa
I've been flying a DJI 4K Mini drone here in the Dominican Republic, so I am interested in the whole drone thing. The technology involved is pretty amazing, with many of the drones featuring GPS tracking systems, onboard compasses, and inertial (gyroscopic) stabilizers. This in addition to high resolution, stabilized cameras, look-down landing cameras, and obstacle avoidance systems. Oh yea, if you lose sight of the 249 gram drone, you can just hit the HOME button and it will miraculously fly to its start point and land. Wow.
This fellow in Capetown takes things quite a bit further. I like his solar-powered drone. He has a really cool workshop. There is something for everyone here: He uses 3-D printing, carbon fibers, and computer assisted design tools. And he does a lot of good-old soldering. I really like his portable wind meter. I will get one for this very windy location in the Dominican Republic.

Some Great Analog Pictures from MIT Building 20 and other Analog Locations
Here is a picture of Jim Williams taken through a Tektronix oscilloscope camera. I never used one of these things, but Dean KK4DAS did. Here are the details of the shot:
I took this great photo of Jim Williams with a Tek scope camera sometime around 1977 or so. There was no digital (or analog) manipulation. It was a simple double exposure. I first shot a scope waveform, then just to see what would happen, I pulled the camera off the scope, stuck it Jim’s face and snapped another shot before pulling the film. I never expected it to look this good….a view from inside the oscilloscope!
Here is the collection of pictures that this 'scope shot came from:

Thanks to Len Sherman for the pictures. On his site you will see, among other things, the upside down Christmas Tree of dead parts, and Bob Pease's Volkswagen Beetle.
