Mmdvm repeater.

From the radio, must set radio to use EXT. DATA SPEED = 9600 bps and use 6-pin Mini DIN cable as specified by RepeaterBuilder.org (pin 4 "PR9" is audio output before discriminator). From MMDVM set TXInvert=0 and RXInvert=1. Note that TX audio gain must be set quite high for DMR to operate properly.
