The H10-76 is intended for military aircraft which use a different standard (dynamic mic, low-impedance earspeakers) from general aviation (carbon mic, 600 ohm earspeakers). I think that if you go through the full audio chain setup, your boom mic will work without modification. Try setting the mic gain slider on the main window to mid setting and then adjust the mic gain in the mixer pop-up window. You might have to turn on mic-boost too. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
