I've done exactly this with my D700. I ran a wire from the
fixed-level RX audio on the MIniDIN-6 "acc" connector to the unused
contact on the mic jack. Works perfectly. <br>
<br>
I've done this on many of my older Kenwoods that use the round CBC-8
mic connector as well. Kenwood uses pin 6 on the round connector on
some, but not all, models for RX audio. There seems to be no rhyme or
reason to which radios came with audio here and which didn't. Some
models have fixed audio here, others have variable levels similar to
the speaker line. On the models lacking this connection, I connected a
wire from the hot end of the receiver audio control pot (i.e. fixed
audio level) to the unused pin on the mic jack. <br>
