Perhaps elimination of the transformers would be the answer.
However what this would also suggest is that the harmonic distortion products are only present on the line output, and not when someone is listening to CW on speakers or headphones. I will have to try connecting the rear speaker or headphone output to the sound card to see if the harmonics can still be observed. ----- Julian, G4ILO.
