I’ve previously had an earlier version of WSJT running with Power SDR on a Windows 7 PC. I am trying to get the latest version (2.3.1) running but I keep getting this message - below. I’m using ComOCom for CAT control which implements COM3 and COM4.
I cannot find that Hamlib is a program running. I really am stuck. Any ideas please.
Hamlib error: IO error
serial_open: Unable to open COM3 - No error
rig.c(758):rig_open return(-6) while opening connection to rig
