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.
