That's the right place. I believe that audio is pre-emphasized. Unless you're feeding your TX audio directly to an FM modulator (leaving the audio pre-emphasized through the controller), you'll want to de-emphasize it by adding a 10 K resistor in series & 0.47 uF capacitor to ground after the resistor. Your audio level will drop after this mod. so you'll need to crank up the RX input level at your controller to compensate. Your controller may also have jumper or switch settings to do the de-emphasis there instead, so check into that as well. Bob NO6B Yahoo!
