Things have most likely changed since this was published, but it's better than nothing.
Seems to be oriented towards the XPR series of repeaters.

Actually to any page at this web site! (even one that just points out a typo).
Mike Morris WA6ILQ paraphrased Doug Pelley WB6TUJ, and added his own comments...
Something for people with an interest in the amateur radio digital modes & systems to really think about.........
"THE BEST DIGITAL SYSTEM IS WORTHLESS IF IT DOESN'T HAVE A WELL ENGINEERED AND INSTALLED ANALOG INFRASTRUCTURE FOR THE ONES & ZEROS TO RIDE ON!"
This includes electrical power, grounding (both RF and lightning), antenna type & placement, site noise, intermod, internal desensitization, duplex isolation, etc, etc, etc.
This is the analog world that every digital system (D-Star, DMR, Fusion, IDAS, NXDN, P25, etc.) lives in and depends on... and there is very little digital test equipment that understands DMR, D-Star, P25, etc.
Build your system as if it is a high quality analog system and only when that works should you flip the switch and make it digital.
And when it comes to EmComm every new digital format further fragments the amateur community and the available pool of EmComm people. The only thing that everybody has is analog FM voice.
