[Elecraft] K3 and HRD

[Richard Ferch]

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 you had not chosen the 
appropriate data mode for PSK, you could be in LSB without expecting it, 
perhaps.

Hold the DATA MD button (also labelled AFX - just above the VFO B knob). 
  If it reads AFSK A (or FSK D), you are actually on lower sideband. 
Rotate the VFO B knob until the VFO B display reads DATA A - that's the 
sub-mode you want for PSK. If my guess at a diagnosis was correct, this 
should help set things straight.

If my diagnosis was incorrect, perhaps there is another related kind of 
problem. Some software reads the mode from the radio but not the 
sub-mode, and simply assumes that Data mode is always FSK, lower 
sideband, with frequency readout = RTTY mark. None of those is true in 
DATA A, and that can lead to a mismatch between the software and the 
radio. This is what happens to me with MixW. I can set it up correctly 
for PSK by manually setting the sideband and inserting a frequency 
offset, but then it is all wrong for RTTY. Luckily for me, the software 
I use most often knows about the K3's data sub-modes and gets them right.
