[Elecraft] K3 and WSJT-X Split operation.

[Mike Cizek W0VTT]

Hello Rick,

You really DO need to use some sort of frequency control, either split or
fake-it, especially in F&H mode.  When you transmit the lower audio tones,
their harmonics and distortion will still be in your audio passband and be
transmitted along with the desired tones.  The purpose of using proper rig
control is to keep the audio tones above 1500 Hz so the harmonics and
distortion are out of your transmit passband.

I run WSJT-X via HRD rig control (SignaLink audio) for CAT PTT (and VFO) 
on the K3.

I do NOT set WSJT-X for any split.  The (sole) VFO doesn't move once set.

In everyday FT8, it's fine to let the audio determine actual frequency 
(the other uses one 'tone', I stay on mine or not, think of it as cross 
band ops).

In hound mode, the change in 'tone' is determined by the program (once 
ack'ed by the fox); no VFO shift is required.

It's been flawless without moving a VFO (except when initially selecting 
a band or changing to the fox frequency).  No added commands to the K3, 
life is simple.

There is a designed lag from keyup to actual generation of tone, which 
is fine, it lets all the hardware (amps, pre-amps) have time to get 
'safe' if needed (the KPA line doesn't require it).

Yes, WSJT-X whines every startup in hound configuration that it 'needs' 
split, but that isn't the case in reality.  This setup works, it's 
simple and simple ROCKS on any day.
