Hello,
I am trying to setup my MFJ-1279 Sound Card Interface to a Motorola GTX radio for use as the transmit side of a repeater using "pcrepeatercontroller" software.
I have followed the 1279's manual and set it up for the following pinout:
6 PTT
5 Mic Audio
4 Ground
No other pins are connected.
The computer keys the interface with no problems, but the 1279 does not key the radio?
As I understand it the GTX uses the same mic. pinout as the Maxtrac so is there something I am missing???

Those are the correct pins but perhaps you're counting them from the wrong end.
Looking into the front of the GTX radio, the tab is on the bottom and pin 1 is on the right. This is probably NOT the same way other manufacturers number the pins on a modular connector.
