@K0NR I’d like an LED panel in the rear window of my car that displays whatever frequency my 2m radio is tuned to.

@Scott_WZ0W sounds like an Arduino project
@K0NR good idea!

@Scott_WZ0W @kb6nu @K0NR there are some cheap ebay frequency counters you could maybe pull an analog voltage from to determine after PTT

@Scott_WZ0W @kb6nu @K0NR you could put the freq counter with a short “bad” antenna near the mobile antenna, it should just get your signal
