Crystal Set & One Tube Radio Plans Plans & Instructions

These switch kits are the output from an effort to keep myself busy while on COVID-19 lockdown. I originally intended to just teach myself how to program and interface with various types of microcontrollers (PIC, Arduino, etc.). So, I bought several of the newbie training kits off of eBay and went to town. After exhausting all the built-in exercises, I went looking for a project where I could use my new-found knowledge.

I had owned an Ameritron RCS-12 remote antenna switch for many years and had always wondered how they selected antennas by simply pushing a momentary pushbutton switch. After opening up the controller, my suspicions were confirmed that a microcontroller was at the heart of the design. So, I decided to attempt to recreate the unit’s features that I used most as a breadboard project.
