Hi You got some answers about mic settings, also selecting multi mode screen, you can see your own audio from AF-FFT MAIN, where are the peaks,,, Do not forget to get your RF energy around 300-2400 or 400-2600 Hz for contest and DX
What I do is use the 101's voice recorder and make some recording. Then transmit them into a dummy and listen on another rig connected to another dummy or disconnected from an antenna, whatever gets the rx level OK. I play the recordings and listen on the other rig. I have to have the mic level right when making the recording, but after that I can experiment with AMC, COMP, and equalizer settings, listen to the effects on the other rig, and decide what works the best.
