I've been playing around with AGC SLP (following Don's webpage), and
noticed that on digimodes I now get harmonics. This should be an
artifact of the K3 overdriving the computer soundcard, right?
I've put a signal at 800 Hz (on the waterfall) and I can see the same
trace at 2400, fainter of course. This spurious signals fades if I raise AGC
SLP, or if I reduce LIN OUT. For SLP = 2 (instead of the default of 12),
I need to reduce LIN OUT to 4 (instead of the default of 10).
I'd like to hear what's your experience with these settings.
