#txaudio Elad FDM-Duo audio level #txaudio


I was reminded just now about some measurements I made on audio drive level to the Tx soundcard in the Elad  FDM-Duo.   

There is a small amount of ALC implemented close to max drive making the audio drive slider on WSJT-X give odd results on TF level out if it's varied during a Tx period.    

Just set it to maximum and don't play around with iut :-)
