Re: Receive FM Radio Station #bitx40

If you don't have a scope, perhaps you have or can borrow a receiver that can tune those oscillators in.
The oscillators are an unmodulated carrier, so best if the receiver is in SSB mode so you can year a tone.
But an AM receiver can be used, it should go quiet as you get near the signal.

If you have a 12mhz crystal filter for the IF, the BFO should be 2 or 3 khz below 12mhz.

First check if your VFO and BFO are working correctly.

Put an oscilloscope to C100 and see if you have a good voltage of your BFO frequency. Check the frequency of
BFO with a frequency counter.
