NOTE 1: If you are using other software than WSJT-X or JS8Call, then QDX CAT commands
should still work with this software. If you encounter difficulties then it is possible that your software
is trying to communicate with QDX using CAT commands that are not supported by QDX. In the
section of this manual on the CAT Test utility (in the QDX Terminal applications), you will find a
listing of the CAT commands supported by QDX. Another useful utility is the log file, which will let
you record all CAT commands received and investigate any issues. If CAT commands are missing
for your application, QRP Labs can add support for them easily.
NOTE 2: As mentioned above, CAT control of transmit/receive switching is recommended. If you
INSIST on using VOX, QDX can support that. For example, you may be using a software
application which does not support CAT control of transmit/receive switching and can only use
VOX. In that case you should change the QDX transmit/receive switching mode from CAT to VOX
in the QDX terminal Configuration utility, which is described in the terminal applications section of
this manual.
