OK Duane...I understand. Yes, I use the AUX I/O pin 4 left audio output to
drive my sound card to display part of the audio spectrum because I'm using
TuneWin to zero beat other stations in CW operation. (takes me forever to
match tones by ear, but can zero beat another signal very quick using
TuneWin.) I just emailed Mark that if I have time tonight I will load v1.371
and see if I can duplicate what you and he are observing. Will let you know.
By the way, if the audio out of pin 4 were to vary under any conditions, I
would know it immediately because TuneWin is on my PC screen at all times.
