Jim,
Your description sounds very much like what would be expected to happen
if the software thought the radio was in upper sideband but the radio
was actually in lower sideband.
You didn't mention which of the K3's four data sub-modes you were using.
Two of them are USB and two are LSB. If
2) You're running and start to respond to a station who calls you
but hear him repeat his call, so you stop sending (ESC). You're
using their Enter Sends Message mode, so ENTER should send
your exchange. But because you hit escape, it now asks the other
station for a fill rather than sending

You don't need anything more than the SSB filter.
I agree with Julian. Remember, it is the DSP that is responsible for
signal filtering. You do not need
Dave,
You should use the line out connector. The level on this output is not
affected by the AF gain controls, whereas the level on the headphone
output depends on the AF gain controls and also on whether or not you
have headphones plugged into the front panel (since the two are in
parallel).
Martin,
As a general rule, before adding roofing filters I'd suggest that it
would be a good idea to first operate for a while with the DSP filtering
at the width of the proposed roofing filter to see whether you are
comfortable with that bandwidth. In the case of SSB, my understanding is
