Athens-Clarke County digital migration

[uga_scanner]

Olympic Place is off of Olympic Dr, just behind Athens Tech. Looks like it's just south of the water tower, on the other side of the campus and Old Hull Rd.

, but everything else is allegedly going to be ADP.

I guess they don't care that isn't permitted according to part 90. I guess the laws pertain to everyone but themselves.

As for the tower site, they're replacing the Athens Tech site (which is on top of a decommissioned water tower) with an installation on a commercial tower in the same area (the American site).

Did they ever bulldoze the cemetery to build the tower? The one next to the stadium?

Are you referring to the UGA mausoleum inside the stadium? I'm not sure if that were ever outside the stadium, or if there were another one somewhere near that part of campus. The only one I know remotely near the is Green Hill cemetery, which is far too much a landmark to bulldoze.

Because s90.553 is in Subpart R. See below.

tower site/decommissioned water tower?

This one is at Athens Tech. Notice the stingers on top and the microwave dishes on bottom. There are two towers to the right, behind campus (out of shot). One stands freely with cell antennas on it, and a guyed tower on a different lot. Not sure if the change will utilize them.

 

[uga_scanner]

My understanding is that one of those will be used. I believe it's the guyed one.

No there was an article someone posted here a while back that they have to exhume the bodies in the cemetery next to the UGA stadium to build a radio tower or something.

That is a massive cemetery, with thousands of graves. Its a national historic site. I highly doubt they would remove any bodies without family consent. There are plenty of other places on an near the UGA campus where an antenna could be places, like the existing tower a the UGA conference center where UGA's TRS antenna is, or the top of the library on north Campus.

 

[uga_scanner]

My information is that the existing tower at the UGA conference center will also be a site to supplement in-town coverage, in addition to the county's 3 sites.

 

[nunyax]

UGA has applied to use it's frequencies at Athens-Clarke county's sites and vice versa for a merged 4-site 12 channel system:

ULS Application - PubSafty/SpecEmer/PubSaftyNtlPlan,806-817/851-862MHz,Trunked - 0006836702 - GEORGIA, STATE OF

From their Intergovernmental Agreement attachment:

The System is expected to be operational and accepted from Motorola by September 30, 2015.

 

[SlipNutz15]

I have a friend who works at AC911 and says they've been testing some radios/consoles on and off and says it sounds very clear. I like looking on the FCC's database for frequency information but apparently I'm looking for the wrong name. Is there a link for the frequencies and locations for the new P25 Type 2 system that is going in?

 

[procopper7005]

I am told the only law enforcement TG's not encrypted will be special event TG's and mutual aid which are heavily used by multiple agencies on UGA game days.

All non law enforcement TG's will be in the clear.

ACC moved over today. Lots of channels encrypted. No fun.

UGA has already moved over - a week or two back.

Thanks for the update. You say "lots of channels are encrypted" -- Do you know which channels are still available?

I've heard Leaf and Limb, Streets, and The Lift (bus). I have heard no open public safety channels. As of yesterday afternoon they had not moved Fire over, but now I'm hearing nothing from the FD, so I don't know if they are not busy or they moved them over and encrypted them, but I have not been listening that much today, and was not listening during the normal radio check (8 AM).

I have not even heard the Clarke County jail, so they must have that encrypted too. You wouldn't want to have citizens hear them calling for a gate to be opened or a prisoner to be moved from one location in the jail to another.

I have heard Parking Services on the UGA side, but UGAPD is encrypted.

It is a shame because the reception of the new system is perfectly clear and much stronger than the old system. We'll see if the special event channels are in the clear (as someone posted earlier in the thread) this weekend since we have a home UGA football game.

By the way, they are using a combination of the frequencies from the 'old' UGA and ACC 800MHz systems (Phase 2 TDMA). 40+ years of listening to public safety gone in an instant...

Ugh. I've been listening for only 10+ years religiously. Like losing a superior version of the newspaper, television and internet all at the same time.

Thank you for the information.
