• Download and install the Virtual Com port software driver. This will allow connection of WSJT-X and RemoteTx Connector.

Create a com port pair group and re-name them COM11 and COM12 (hopefully they will be available.)
The icon to start com0com is found in the com0com folder in the windows start menu. It is named ‘Setup’.

 

• Download and install RemoteTx Connector software. It will give some warning messages because the install package is not digitally signed. It will put a startup icon on the desktop.

• Setup WSJT-X to use the Kenwood TS-480 radio on port COM12 (higher of the 2 ports you set up above.)
  Make sure baud rate is 4800 and PTT method is CAT.
  

• Start RemoteTx Logger and set it to COM11, check Tx Enable and VFO Enable and then choose appropriate port, baud and radio settings.

• Make sure that the radio control interface is running in the web browser and click the Digi-Monitor ON. (This allows you to see when the radio is transmitting and receiving when it is controlled by WSJT-X.)
  Also, the MOD-SOURCE should be USB and output ALC can be adjusted by ‘USB-TX’ as well as WSJT-X output level adjustment.
  
• Click start on the RemoteTx Connect program to connect it to the radio.
• Start up the sound interface on the RemoteTx Audio tab by clicking ‘Call Radio’.
• Now, start up WSJT-X and the radio should now be under it’s control.
