[ICOM] Dualing mic jacks issue

[Gary P. Fiber]

Its typical as the front mic jack is not switched off the mic element is 
directly wired for VOX purposes. Its that way on most of the older Icom 
transceivers that have a rear mic or accessory jack input.
some had a Data setting that would turn off the front panel mic jack. 
The old IC0765 comes to mind for that and there were others.

It is working great on RTTY-already bagged 2 new RTTY countries (PJ2 and CP).  I also get the receiver audio off of the mic jack, so I dont have to tie up the speaker on the rig.  I figured it would be easy to plug this cable into the rear mic jack, and leave the microphone plugged into the front jack.

With both the RTTY cable and mic jack plugged in, RTTY still works fine, but the microphone will only put out a few watts on SSB-it wiill send a FM and AM carrier ok, though.  This occurs regardless of which jack the soundcard cable is plugged into and which jack the microphone is plugged into.
