I've been working on the FCS-152 again. Ported the satellite tracking code to it.
It has an ESP32 and spiffs, so it has excellent codeplug management and can download TLEs. This means on-radio doppler correction is working.
Unfortunately, the retuning for doppler interrupts audio. I've made the auto-correction interval adjustable as a result.

But my favorite part is the completely onboard web-based CPS. And I have to get at least the dynamic channel selection on every other radio.
