Hi Alex,

OK, try this. Change "Settings->Radio->Rig" to "Hamlib NET rigctl" and "Settings->Radio->PTT Method" to "CAT" for each WSJT-X instance you run.

Open a CMD prompt window and type the following command:

C:\WSJT\wsjtx\bin\rigctld-wsjtx -m 3081 -r COMx -s y -p COMz -P RTS 
-Cptt_share=1

where 'x' is the CAT serial port number of your IC-9700, 'y' is the CAT baud rate, and 'z' is the PTT serial port number.

The above command starts a Hamlib rig control server to serve your IC-9700 with Hamlib clients over a network connection. The adjustment to WSJT-X radio settings tells WSJT-X to communicate with the rig control server you have started, and also to do PTT via that server. You may get a message from your firewall application to asking to allow rigctld-wsjtx to accept network connections, which you should allow.

Do not start Omni-Rig, you do not need it.

This will do exactly what you need, you can make a short batch script containing the above command to start the Hamlib rig control server.

If you are only using a single instance of WSJT-X the next release of WSJT-X will allow you to configure that instance to talk directly to your for CAT control while allowing other applications to access the PTT port when WSJT-X is not asserting PTT. For now, or if you use multiple WSJT-X instances; the approach above will work.

Hello Bill

Yes I use only 1 CAT controller transmitter, the IC-9700, I don’t have any other CAT application accessing my Transceiver.

Alex,

let me try again as you have not answered my question. I will qualify it a bit which may help.

Are you only using one CAT controlled transmitter and is that your IC-7900?

Do you have any other applications that require CAT access to your transceiver(s)?

Note by CAT control I do not mean simple PTT control using a serial port control line like RTS or DTR alone.
