Pat,

As I said in my previous message, none of these systems are compatible 
with one another.

Just as background, system fusion uses C4FM and has two digital modes, 
wide and narrow.  IDAS/NXDM uses 6.25KHZ channels and is FDM.  DMR is 
TDMA with 12.5KHZ primary channel with two virtual 6.5KHZ channels.  
Apco25 version I uses 12.5KHZ FDM C4FM channels while D-Star uses FDM 
with a 6.25KHZ channel.
