No, it was a spurious emission from something but I'm not sure what.
My latest experiment of playing with L34 and SG is much cleaner:

AF Gain was set around 2-o'clock with very little gain on the line
input level of the sound card as shown here:

I can get rid of the noise completely as spectrogram sees it but the
signal drops about -25 dB.  I hear white noise along with the signal
when spectrogram sees nothing.
