Sorry folks, I should have told readers the recording was made with the antenna connected. ??
The crackle is ALSO present when the antenna is disconnected.?
I have not confirmed this but I suspect that when starting the QCX when it's "cold", there is no crackle. ?Then, as it "warms" up the crackle develops and stays. ?Its frustrating. ? Is this possible??
In any case, thanks for listening... and responding.
