Hello,

I made a remote installation for my FT857D with version 7 board.

All is ok (remote head, receiving audio, ptt), but no ... tx audio.

Does anyone have an idea of what could be wrong?

 HI

What kind of mic do you use ? It must be standard  simple MH-31. The MH59 need 5V power which Remoterig do not supply.

If you already have the MH-31 check the red wires and the codec gain settings

Hello Mike,

Thanks for your fast answer.

I'm using an over Mic (AV908) witch i have tested before leaving the remote site (on the ft857).

Codec and strips seems ok (on the 2 site). I will ask a friend to change some of them on the remote site.

If a mic works connected direct to the FT-857 doesnt mean that it works with the Remoterig as with the MH-59 as the Remoterig doesn't have any 5V out

AV908 take a 8V (but i think it's for the up down button)

On witch pin goes the 8v from RRC please? -- I found the pin, but still no audio - I will ask a friend to verify if there is no problem with the red wire
