Atlanta P25 System active now with City School Buses & More

The Atlanta City Digital system is now in operation with the city school buses migrated onto it. Most busy is 19590 and 19594 but I believe they also are using 19592 and probably something to do with 19597. Old Analog talkgroups Sewer 1 and Sewer 2 are being patched over on digital 19477 and 19478 respectively .Also getting unconfirmed user hits on 19602 and19502.

CORRECT Atlanta P25 Frequencies

OK folks - I've compared the FCC license for the new Atlanta P25 TRS with the frequencies listed here on Radio Reference. The freqs listed here on RR ARE correct. However, there are 10 additional frequencies licensed by the FCC as part of this system that should be added to the database. I cannot tell you which one(s) of these may also be control channels but you should be able to detect them. Add these to your database for this system:

851.0125
851.5125
852.0125
852.5125
853.0125
866.0125
866.5125
867.0125
867.5125
868.0125

Whoever figures out the new correct control channels, please post them on here. THX

Update

After posting the frequencies above, I just realized that the FCC had included in their license for the new Atlanta P25 system the REBANDED I-TAC frequencies. So, I would think you would NOT want to include the following in your scanner for this system as the following freqs are listed in RR Wiki as being the new, rebanded I-TAC freqs:

851.0125
851.5125
852.0125
852.5125
853.0125

Sorry about that

 

[N8IAA]

Mike, the CC's are as follows, 857.7875c, 857.4875a, 857.4625a. These are what I have programmed in my scanner. Also, have 855.3625, 855.5125, 856.3625, and 856.4875 as data channels.

Frequencies

Larry - I looked closer at the frequencies you listed and they aren't listed here on RR for the Atlanta P25 system. So, are the freqs listed here on RR all wrong?

Yep. They obviously rebanded and are using the new CC's. Zigra1 posted the the 857.7857 on the ScanAtlanta yahoo group. The others I got running Pro96com.
