No audio or waterfall efter remote switching on/off

I just manually put in /dev/IC7300 (does not even exist on my laptop) and I saved the config.

roeland@snowpa:~> grep ^SerialPort /home/roeland/.config/wfview/wfview.conf.pa3met.7300
SerialPortBaud=115200
SerialPortRadio=/dev/IC7300

Yes, the log file now confirms that the server wfview uses the IC7300 device.

Thank you for your patience, I did not realize I should edit the config file!

I entered in the manual box, saved it…

Anyways, it works!

Maybe the issue is that the UI does not populate with the manually-supplied serial port. I think the program will respond and use the manually-supplied port though.

Both are correct yes.
