Remember these things?
The Radio Shack crystal radio kit - a tuning capacitor, ferrite antenna bar, and a 1N34A diode on a little breadboard device that was reused for many different things - including an AM transmitter kit. These generally ran $10 for years, and this appears to be a later unit made in China.
I had one of these when I was a kid, but didn’t really appreciate it. Now I do, so I found one on an auction site and plan on building it. I’ll scan and post the manual as well, so stay tuned!
I would like to find out what the bar antenna is, and if they’re still available. They seem to have a million uses.
If you’d like a manual scan, you can download it here. It’s about 1MB, and is a 600DPI PDF: https://privateemail … 8376/1/8/NDY/NDYvMTY
