K3 and HRD

[hf4me]

Either I have something set wrong in my K3 or in HRD and I do not know IF that is true or which one is set wrong.

Waterfall with the actual frequency being displayed on the ruler bar above the waterfall:
Radio set to 7.035, data mode, PSK signal showing at 7.037, tune radio to 7.036, frequency bae slides downto the left as it should, signal slid UP and audio frequency increased, and the signal is now showing at the indicated frequency on the ruler bar at 7.038.  OK, this indicates to me that the raio is in data mode (functioning as LSB.  IF I use Data Reverse, all is well.  SO, does HRD "assume" the radio is using data mode (functioning as USB)?  Where is the setting where I change this?  OR do I have something set in the radio that causes it to use LSB instead of USB for data mose?

If any of this makes sense, please comment.

THANKS, es 73, de Jim KG0KP

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.

Thanks guys, yes, I had been messing with the data modes and left it in
AFSK, back to Data A and it is all well again.  And thanks for the
explanation of which way the Data modes are.  Nice to know.

73, Jim
