Chattanooga/Hamilton Co - Site 03 Catoosa Co.

[hcpholder]

I see the Site-03 Catoosa County shown. Site-02 is on "our system" and a "control channel" is shown for the site. I have seen the notes that Catoosa county GA will be on "our system" also, but no "control channel" is listed. Is this still "incomplete" information? I see various "Admin names" associated with the "history" changes, but no one seems to stay long. Who should such questions be addressed to? Thanks

Re:

The Rinngold tower is not yet firing. It was supposed to be up last month, but always expect delays!
It will work just like the Brock Road site; it will handle all radios in Catoosa that detect a stronger control channel signal, but other radios will affiliate with the Chattanooga towers if the radios get a stronger signal from there. So you'll hear Catoosa talkgroups on the that system simulcast on the Chattanooga "main" system.
Dunno what the delay is this time. It was supposed to be running back in March, then June and now who knows.
If you're in Hamilton County, listen on the "main trunk," if your in Ringgold listen to that system.
FYI, word has it that Walker and Dade counties have applied for federal homeland security grants to also join the system. Whitfield was approached but for now they've declined. We'll see!

Thanks Butch. I have an old TrunkTracker scanner that I can program the talkgroups in for Catoosa.

Still listening, but not activity with the TGIS's listed. I wonder, if Chattanooga is going "digital" (new digital ID's are showing up in database), will Catoosa wait until digital system is fully operations before using their equipment? Guess we will have to wait and see!

Well here's some good news my friend. With the existing talkgroups used by Catoosa Co, it is very unlikely that digital transmissions will be deployed. Here's why. Digital talkgroups usually are transmitted in the 30000 and above range on mixed mode systems. So if Catoosa County has a talkgroup of, let say, "32524", then this talkgroup will more than likely, be digital. Any talkgroup below 30000 will be analog.
Take a look at Nashville, Memphis or Birmingham's system to verify this information.
Thanks for your time.

Nashville ID's vary from 10000 up in the 50000. Memphis also. Knoxville is not showing any "digital" listings. I wonder of any of Chattanooga's TG's will change! Thanks for your time Lt. Great to hear form other local folks.

Oopse! Got Knoxville and Memphis mixed up! Go figure.

Re:

Look at the Chattanooga TRS, and at the bottom of the Hamilton County Services talkgroups you'll find the first full-time user of digital, the new school bus company.
It's 33040, and along with a handlful of other digital groups that were used for testing with PD and sheriff's dept, digital does seem to be stacking up north of the 32000 mark.
Some police are getting new XTS 5000 radios(about 4-grand a pop), but I wonder if they'll be obsolete by the time the migration to digital happens. Catoosa will use their new digi radios in analog mode until everybody north of the border goes digitial, so it'll be a while for them. BTW, Catoosa's ready to make the move to 800, but just waitin' on Ma Bell to make the connection. As she gets up in her years, it takes longer for her to move those granny flaps.

You are correct on the Nashville and Memphis talkgroups. I stand corrected on the information I gave you. But as far as Chattanooga's system, anything above 30000 has been a digital talkgroup.
Most systems that's been migrated from a type 2 to a APCO mixed mode system, will more than likely have the same setup as ours. Those built from the ground up, like Nashville and Birmingham, the digital talkgroups seemed to be universal. you see, systems like Chattanooga have existing analog talkgroups in place. Therefore, the analog talkgroup has been preseleted in the system and may not be used for digital comms. Here's an example of what I'm saying. CFD uses analog talkgroups for dispatching and routine communications. The dispatch consoles, mobile radios and station radios are analog only and can not decode digital voice. But our portables radios are P25 capable. So by simply assigning us a talkgroup above the 30000 range , the portables can transmit in digital voice. The only reason CFD will not do this is because the dispatch consoles can not monitored our traffic, if we have a talkgroup in the 30000 range. And until the consoles, the apparatus and the station radios are upgraded to use digital voice, it's highly unlikely that digital will be used for CFD traffic.

Actually, it may be worse than that... it's Ringgold Telephone Company down in that neck of the woods, so not only are you talking about getting the leased line turned up, but it involves two different companies (RTC and BellSouth)...

I've had some hist on the 24080 and 24464 ID's this morning. Also see some ID have been added, and changed.
