Si4732 frequency calibration #77

Open byteborg opened 1 month ago

byteborg commented 1 month ago

Would there be a possibility to store oscillator calibration for the Si4732? I made the mod and my device seems to be about 1.49kHz too low at 14MHz which practically inhibits tuning to CW on a somewhat sane frequency grid. It'd be great to store oscillator calibration in firmware and be able to display and use the corrected frequency.

Yes, I've noticed the approx same frequency offset on my receiver.
