When switching between devices in gqrx the gain control changes will segfault the application. Fix this by deleting the “gains” section in:
Sending gqrx audio to fldigi
Install fldigi with yum
Configure fldigi sound card to use pulseaudio, leaving server string empty
Launch pulseaudio volume control, and under recording tab, fldigi capture from monitor of built-in audio analog stereo, and set level to 0 dB.
Adjust fldigi waterfall upper signal level and signal range.
