I have not noticed this with my K3, using both a cheap SoundBlaster audio
card and an expensive E-MU card. My first suspicion would be something
impeding the audio getting to the transmitter - K3 equalization, sound card
equalization. Are you using the line in audio source? Check settings for
it. I can run PSK31 with only 2 audio cables between the sound card and
radio line in/line out.

Just getting my new K3 working on PSK31 and noticed that it seems to be
important to limit the range of the transmit frequency. Using Digipan and
K3
Data A mode, if I select a transmit frequency on the waterfall that is too
high or low, I will get very low (or zero) power output. It seems like one
needs to keep this frequency centered in the transmit filter bandpass (I
use
the 2.7 kHz filter for transmit) -- so should I always transmit near 1.3
kHz? I never noticed needing to limit this range when using my IC-756 with
Digipan.
