Hey Mike,
Good to see you visiting our wonderful state!

Do keep in mind that Troopers are usually assigned a specific district and don't move around a whole lot. What you heard was an anomaly and not the normal day to day SHP Comms. The system could quickly be overloaded if every trooper decided to listen to the SHP District across the state. Usually Troopers have enough to handle just keeping up with traffic around them so my guess would be a VIPER Technician had his radio on the SHP talkgroup in question. Or an SHP higher up personnel.
Comms in a statewide smartzone system can be contained within a specific area a number of different ways at the zone controller. A Talkgroup can be assigned a specific area, and if the user on that talkgroup wanders outside of that area they get an "out of range" message. Same thing for the Radio ID (RID). The Rid can be programmed to a specific area.
Just a way to maintain system resources and try to use them in the most efficient way possible.

Drafin is right on everything he said and especially right when he said:
It's not uncommon to hear very odd talkgroups in some very strange places
That's one of the many things that makes monitoring VIPER fun. You never know
which talkgroups are going to be active where

That's why it is a blast to keep the scanner in Search (or Open) mode.
Never know what ya might hear

Happy Monitoring (and happy vacationing!)

Thanks, Drafin!
That certainly makes sense. Since most states tend to move their state police/troopers around other other posts/troops from time-to-time, it would make sense that the system would have the capability to responding to the troopers "current" location rather than confining them to their "home" area.
I've really enjoyed monitoring the VIPER system when we're in the mountains. Even though Macon County hasn't placed any agencies on the system as of yet, I enjoy putting my scanner in "SEARCH" mode and seeing which different talkgroups I can receive.
I appreciate the quick response.
