Hi Mike and others. What is the best way to calibrate CW RX BFO using the KD8CEC firmware.
There appears to be little written about this elsewhere so I was wondering how successful you were in sorting out receive in CWU and CWL by tweaking the CW RX BFO settings? How close did you get to sharpening up the reception of CW signals using the CWU and CWL modes in the KD8CEC firmware?
Did you use a signal generator or CW signal on a known frequency, or did you just tune to a strong CW signal and tweak for best audio? What have others done to obtain the best results?
