I did not go mobile, but rather made a recording of the audio on my ICOM transceiver. These were my final settings after trying various settings on my QMX with the Heil Pro 7 (IC)headset. I worked a couple of POTA stations who said my audio was clear, just weak. I left some heading words out but I think you will get the idea. Hope this is helpful.
