Mmdvm repeater.
MMDVM Repeater This is a multimode digital repeater that is setup to handle both D-Star and Yeasu System Fusion (C4FM) traffic. Either mode can be used locally (both unlinked), or linked to various D-Star or YSF reflectors. D-Star linking uses the standard commands as outlined below. YSF linking uses Wires-X commands (see the Yaesu Wires-X ...
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).
