Just wanted to let you know that after a month of using my FX1 setup, that I’m getting excellent reviews of my audio. I tweaked your initial settings and had my son talk on the radio and the audio is clear and natural sounding just as it should be. I have been able to make contacts that my regular mic wouldn’t have produced the audio to get above the channel noise and clutter during peak conditions and works excellent on sideband too. Also thanks for the quick turnaround on the plug and cable that needed replacement. I would recommend your product to anyone who wants better audio for their radio. Thanks.
