Just finished assembling my 20m QCX+ and in the process of calibrating it.? In the process of adjusting C1 for peak, I am unable to get BPF amplitude scaling factor above 3. Twisting C1 brings it up and down between 0-3.?On key-down, I have output of ~4 watts while supplying it with 13.8 volts DC.
Any suggestions to boost the amplitude scaling factor above 3?
