Hi fellas, is there any mods to improve the audio quality of the MH-34b4b Spkr Mic with the FT50R HH, has anyone drilled any xtra holes in the case near the pickup ?? TX audio from HH's Mic is much better than the MH-34b4b anyone had a fiddle with this..also any comments in regards the EAR PIECE MIC that is sold after market to suit these HH's. Kind Regards dennis vk4sx
