SDTRUNK System
I was able to gather information from FCC records while on a visit to SE SD. Also there was plenty of information via google search. My uncle is in county gov out there and reported that they had over a million hits (per month?) pretty much equally divided btw, State and other agencies, i.e. federal, local. Even the Civil Air Patrol is assigned talk groups. I DEFINATELY plan to have a digital radio on my next visit out there.
There is also a web page. sdtrunk.com? that has a radio users guide. This has been a major problem with so called non performance of trunked systems. Lack of user training.
Another think S Dakota has done is put state radio admin under IT folks rather than Law Enforcement. This profides an arm lenght approach to system design and management and IMHO, this has contributed to the success of the system in that it was designed with no pre concieved ideas but rather starting from zero with user NEEDS being a priority.
In reviewing the FCC records, you will see that the assigned frequencies come from many different radio services.
South Dakota folks seem to know how to "Git er Done"!
