Atlanta 800mhz Help!

[WeBeCinYa]

Hi I am new to the Atlanta area and realize that the Atlanta police are on a trunking system, but I have a Uniden Sportcat 180 scanner and was curious if there were any 800mhz freq available that were repeaters? Also does anyone have a current list of Fire, Rescue, ect that would be good for most of Fulton County?

Thanks!

At this time, city of Atlanta is switching to a digital P-25 system. Fulton county is still analog. You can monitor their system until the change-over. All of this can be found here on the database. De Kalb is still analog too. Gwinnett, Cobb, Forsyth, and Hall have gone P-25 digital. Hall is totally encrypted. Gwinnett FD can be monitored, but not PD and SO. Cobb and Forsyth allow the public to monitor them.
HTH,

clayton is completely analog with only a couple of SO Channels encrypted. Clayton PD only has SWAT and Channel 7 encrypted. Clayton EMS is fully open.


where about in Fulton are you?

Don't forget Cherokee County as well. All VHF HiBand.

don't forget about MARTA.

MARTA uses a Motorola Smartzone 4.1 mixed mode (analog/digital) 800MHz trunked radio system. Police talkgroups are digital, bus and rail operation talkgroups are analog. MARTA's TRS has some pretty amazing coverage.

and Paulding and Douglas as well, VHF except the city of Dallas ONE USER Startsite 800 system and Douglasville's underutilized 800 analog TRS!

Douglasville FD and other public work groups use a VHF LTR system, and Paulding also is licensed for a VHF analog trunked system for public works, etc.

City of Marietta has a VHF analog Passport trunked system shared by all non-PD/FD agencies (BLW, streets/roads, parks/rec and BOE).

All Atlanta city public safety is on the Atlanta 800MHz Smartnet II TRS, soon to be on their new Astro 25 digital TRS.

Cities of East Point, College Park and Georgia State Patrol troop C are also current users of the Atlanta city 800 systems.

All Atlanta airport PD/FD and other PS operations are on the Atlanta system as well.

The State of Georgia has their own analog 800 system, users include the capitol police, GSU PD and sometimes GTPD uses it (they dispatch on their own 800 conventional channel however) and is located downtown.

Fulton counties' 800MHz Smartnet II analog system carries communications for:

all Fulton county government (FCSO, FCPD what remains of it, FCFD, public works, water, etc)
Grady EMS and Rural Metro EMS
all of Sandy Springs FD/PD, Roswell PD/FD, Alpharetta PD/FD, Milton and Johns Creek PD/FD
city of Hapeville PD, city of Fairburn PD/FD

MARTA has their own mixed mode digital system (Smartzone 4.1) on 800MHz
MARTA PD is digital, MARTA bus and rail operations are mostly analog

as others have pointed out, a digital capable scanner will be needed if you want to monitor digital systems which most agencies are being pushed to move to by Motorola salesman.

Re-banding is also happening which, thanks to Sprint-Nextel, we have to reconfigure every single 800 public safety system in the country, to minimize interference from Nextel sites to public safety systems.
As a result, many older trunk tracking scanners will not work correctly on the re-banded systems. Most newer digital scanners can support re-banding, visit the RR Wiki for model specific information.

Talkgroups for the above systems are well documented in the RR database.

Thanks for all the help guys! All this info is very helpful and should have me busy for a while. I don't find in the data base the 800 mhz freq listing though. Am I looking up something wrong? I see codes that look to be trunking codes but not a 800 mhz list. Could someone point me in the direction? I am looking for Atlanta Police, Fire, EMS in particular. I live off of Roswell Rd in Buckhead for the person asking!

Thanks again in Advance!

the frequencies for the aforementioned trunking systems are in the RR database, listed right above the talkgroup ID's.

Control channels (if known) are in RED, with alternate control channels in BLUE and remainder of voice channels in BLACK.

you will have to program your trunking scanner accordingly. Some require only the control channels, some require all the control and voice channels to be programmed, some can do either/or. Then you have to program the talkgroup ID's in a scan list that you wish to monitor on for each system. Some older trunking scanners only let you scan one trunked system at a time. The RR Wiki is your friend has has tons of info on the different models, capabilities and programming tips.

Doesn't Douglasville PD work off of the Cobb P25?

Not that I am aware of, currently listening to their Smartnet system as we speak. Pure analog, no digital sounds coming out of my radio!

I know they've always had TG's on both Cobb's digital and analog system as a backup, as does the Douglasville system which has Cobb backup TG's. But they are totally separate systems and Douglasville is still using their own TRS as they have since the early 1990's.

Sportcat 180, all frequencies need to be programmed in.

Athens-Clarke County is also 800 analog...type II if that's helpful. We live in a great age though, don't we? Gwinnett and Hall Counties both have their illustrious super secretive 'Mussolini' encrypted P25 systems that they don't want anyone to listen to. God forbid the listening public should be able to monitor traffic stops.
