I've seen a lot of discussion lately around this and I get the idea in
theory, but in practice it can be difficult to know if you're doing it
right.
On my Fedora 25 system using the pavucontrol app if I set my Input Device
-> Microphone volume to 100% (which says it's 0dB) the incoming signal is
way too hot and I have to change the slider in WSJT-X almost all the way
down.
My current setup for recording is:
Application based recording volume is set 100% (0dB)
Input Device set to "Base" 10% (-60dB)
Slider in WSJT-X in the middle 1/3 of the slider to get 30dB during
non-transmit time.
Should I not be using the Mic input and use Line In instead? Will the
results be different?
I'm even less sure what to do about the playback volume.
Application based playback volume set to 100% (0dB)
Output Device -> Line out volume set to ~50% (-19dB)
WSJT-X Pwr slider set about 6 notches down from the top to get ~20w out.
Thanks,
