KPA-1500 changes modes

[Richard Zalewski]

I have been experiencing an intermittent problem with the KPA-1500,
TS-990.  When running WSJT-X (USB) occasionally the 990 goes to AM-D1
mode.  No reason I can see for it to do that.  It does this in RECEIVE.
Just to be sure however I put lots of ferrite on all leads involved..

HI,
My experience is that you should use OmniRig as the control in WSJT-X.  Do
not use HamLib.

Sounds like an issue with the WSJT-X (Hamlib) software not the
KPA-1500.  I suggest you take the matter up with the developers
or WSJT-X and hamlib  <[hidden email]>

Are you using the PC DATA connector to have the KPA1500 automatically
follow the frequency of your transceiver?  If so, try setting MENU:RADIO
POLL OFF; commands from the amp. could be interfering with radio commands
from WSJT-X/OmniRig.  You might also try a slower or faster baud rate in
both the radio and in OmniRig.
