For multi protocol module A:
DSTAR: Either REF305A,DCS305A, or XLX305A. Please use the native XLX if your software supports it.
DMR: XLX305, connect to talk group 4001
YSF: XLX305 OARC
You can use whatever mode you wish but bear in mind that DSTAR or DMR are the native modes, DMR to DSTAR and DSTAR to DMR requires hardware transcoding and CF4M requires both hardware and software transcoding.
