[Elecraft] K2 SSB audio......

Wed Feb 13 21:10:53 2002

I spent a lot of time fine tuning the TX audio of my K2.  The BFO settings
tailored to your voice tones and mic you are using is critical in getting as
much as you can through the narrow SSB filter.  I can not imagine doing a
good job aligning all the filter settings (CW) without the aid of
Spectrogram.  On SSB you need Spectrogram and a receiver to monitor output.
Using the Heil MH2, unless my signal is weak the best audio settings are
SSBA 2 and SSBC 1-1 (no compression).
I have also found that the LSB (used on 80-17m) sounds better (TX audio out)
than USB no matter what BFO setting I try.  It sounds clearer and cleaner.
Luckily the "good" sideband (USB) is used on 15-10m.  Not a big difference
but noticeable.  Which means on 20m and 17m (USB) the muddier sounding
sideband is in-line.  With careful alignment you can get good crisp
communication audio out of the K2.  It is not "Hi-Fi" audio, was not
designed to be that way.
