Don,
The "anomaly" is present regardless of BFO setting both in waveform and audio.? If I let the probe "hang" and just connect the ground wire to B- the drone/hum goes away.? I have disconnected the probe from the scope and the drone remains.? The probe must be plugged into the scope.
I'm going to take a break from it for a little while and play with the Zenith TO the XYL brought home the other day. :-)
