[Elecraft] [K3] Harmonic Distortion

[Mike Scott]

>The "problems" people are having with "harmonics" when they listen to CW
with a 2.7KHz filter/DSP setting seem to be easily solved by just reducing
the DSP bandwidth.

If you were paying attention to the spectrogram plots you would have noticed
that the IMD and harmonic products are showing up far outside the bandwidth
of the DSP filter, very far. The distortion products are being produced in
the analog domain after the DSP digital to analog conversion. No amount of
DSP tweaking will fix this.
