I'm building a solid state power amplifier for amateur radio. I need to get just the MHz that the amp will be fed (1.8 to 54MHz). I am using the stock FrequencyCount with a Teensy 4.1. It is accurate to 30MHZ and not any beyond that. I would think that with a 600MHz clock, the Teensy could handle that.
Am I right? Where do I need to look?
