Under Latest News Update Posted on 2011-09-01 15:00:51 it states "They will be switching to Pro-voice sometime on or shortly before 2015.".
I assumed this be the case as the OP is unable to monitor same. A little more information is needed, such as what he has tried so far to do so. The 500 should receive EDACS Standard just fine, or has he programmed an EDACS system as P25?
Confirmed Belton and Temple are full ProVoice as of (at least) October last year, using different talkgroups than what is listed in the DB. Bell SO and the rural LE and VFD channels are still analog. Not sure about Killeen.
I tried unitrunker once but I'm not an expert.
I guess the tow truck driver I spoke to was full of it, or didn't know what he was talking about. He claims he scans TPD, but he left his radio in his tow rig.
I didn't confront him about it because we were around friends.
