Georgia Tech Going P25

[Thunderbolt]

I see that Georgia Tech has applied to upgrade their current 800 MHz TRS, from analog to P25. Does anyone know when the changeover will take place?

Ga tech switched from analog conventional to p25 conventional encrypted at least 5 years ago. They've never had a trunk system

GA Tech New 800MHz P25 System

Hi Guys,

GA Tech has a brand new 800MHz P25 Trunked System. It just went live a few weeks ago.

What frequency is the control channel operating on, and do you have a System ID and WACN for it?

Yup. AES-256.

I've been trying to sync up what I've been hearing when monitoring Georgia Tech with what I've read in this forum.

I know Georgia Tech PD used to be on 853.3125 conventional P25 encrypted. Since they left that frequency I've regularly listened to them on talkgroup 19350 on the City of Atlanta P25 system (unencrypted Phase I FDMA). That talkgroup is listed in the RR database as GTPD's Channel 2, but it sure does sound like their regular dispatch channel, at least lately (I don't listen to them all that much).

On the newish Georgia Tech P25 TRS (SysID 0Bh), I hear what sounds like security personnel (not police officers) on TG 251. They are using Phase II TDMA unencrypted there. But I'm not hearing anything that sounds like PD, or seeing much in the way of encrypted talkgroup activity on that system.

I'm far from an expert on Georgia Tech radio usage, but thought I'd share what I'm hearing and see what others think.

Georgia Tech PD Dispatch is definitely TG 19350 on the City of Atlanta system, unencrypted. Just heard them dispatched to a car break-in at a student apartment complex on 14th street, and the responding GTPD unit sped past me a minute later on my way to work in midtown.
