Glad you are making progress. I need a little help in understanding what you mean by “oscillator whine”. Please give a description. I checked your site and your nice construction is pleasing to view. It appears that you have not substantially changed the circuit. Did I miss something?
Under what transmitter and receiver situations do you hear this?
Is it there with no modulation? Low modulation? Full modulation?
Is it happening when you are close enough to the transmitter with the receiver where the other stations on the frequency are swamped?
Anything else you might report might help us help you “bring this baby home”.
MRAM beat me by four minutes. I have to learn to type faster but for now he’s the champ!
