G'day,

| Today I fed an S9 CW signal into Spectrogram and find that its third
audio
| harmonic is down approximately 10 dB from the fundamental.  The 5th,
| 7th, 9th, are down about 4 db sucessively from the next-lower odd
| harmonic.

Sounds like overdriving the sound card to me.  I never run Spectrogram
above -30dB for that reason.  Turn down the line input on the PC.

Regards,

Mike VP8NO
