Update on the ModularTuner and other projects

Post by profdc9 » Mon Nov 04, 2019 5:05 am

I have been building an automatic antenna tuner for amateur radio using the Bluepill as its brain. This device impedance matches an antenna to a transceiver automatically. You can see it in action in this video:


The relays clicking are the tuner selecting the inductors and capacitors to best match the antenna. The github for the project is at


Also, I have been working on a Vector Network Analyzer, a device for measuring RF components, you can find here:


And I have a Theremin that uses the Bluepill


These all use Roger's stm32duino core.

Thanks for reading!
