I have an Yaesu MD100 mic with an Yaesu DX5000. For some reason I cannot get the tone control on the bottom of the mic to work. When I switch the main control to filter and high emphasis or low cut is engaged the the audio is terrible. I have tried all combinations with the same result. The mic works great with the main switch on thru. Just wondering if anyone has run into this. I have owned the equipment since new. Thank you in advance,
