I've been following the system since it first got grants to put the switch in in Chattanooga.
It was the Tennessee Valley Radio Trunking System, and covered some of mideast tennessee and part of georgia. Now, it's morphed into the statewide something something system. TACN?
biiiiig motorola Astro 7.4 P25 system. Mostly 700Mhz. And, getting ready (if not already rolling out) to go to yet another standard.
Many areas are encrypting, which is a poor decision.
OP, I don't know where you live, but the system is kind of unforgiving. Either you're in the repeater, or you're not. They are being skimpy on the repeater sites, only to have to add coverage.
You can monitor it now with a new scanner, but when Phase II or whatever the next iteration is rolls around, it will be awhile before the scanners catch up.
There are some inherent issues with how this is rolling out, but it is what it is. Ask for car radios and don't trust using just handhelds and don't trust the techs doing their driving tests. I listened to them do all of Blount Co, and they still had issues afterward that had to be addressed.
Pros - no more six radios in a car.
Cons - wait til a serious multiagency incident happens. bah-bah-bah. system is busy. bah-bah-bah
sketchy coverage, 700mhz is a shit band for public safety.
you are carrying a tiny computer that runs a radio.
You probably wont be able to use a stubby antenna.
there's more, but it's bedtime. Hope you don't have to buy your own radio!
