I have had my SDS100 for a week. I programmed the GSP all troops using Sentinel and have not heard any radio traffic. Are they using a different system or does anyone have any tips for me?

GSP in north Georgia on VHF P25 conventional is currently in the clear, but you may not hear VHF without a good outside antenna. Newnan and Villa Rica repeaters are very active.

As mentioned, their activity on troop C in metro ATL takes place on Cobb, Atlanta and Gwinnett trunking systems and are encrypted.

GSP will be moving to Southern LINC LTE on L3 Harris subscribers over the next few months, and will be moving off VHF P25 outside of metro areas and onto LTE. The XL series subscribers will be replacing Moto APX equipment and will still be cross programmed on various trunking systems as they operate today.

Excellent, thank you for the detailed information. I am sure I am just too far away to pick up any radio traffic. I am using the OEM rubber duck antenna.

Say It Isn't So! :( I figured and hoped they would build out and use the downtown Atlanta trunked system that the state owns.

They technically are. The state's VIDA core could host BeON. Not sure if the state went with a cloud based BeON server or will leverage the one they have, but either way, the deal is done and SoCo will be the FNE for places outside of metro areas. The Harris XL series are approved by both SoCo and FirstNet, as well as Verizon FrontLine.

Will be one of the truly converged statewide systems. We (Fulton) have had SmartConnect since 2022, We have a small number of APX NEXT and N70 radios on our system, using both Verizon and FirstNet. Also have some APX6000 BNs school police are testing over the school wi-fi for coverage enhancement. Sure beats plastering costly and wonky BDAs up in every school.

With a moderate external antenna, you should be able to hear Griffin, and possibly Thomaston on VHF- the key to success is an outside antenna away from sources of RFI. VHF, unlike 700/800, is a trash can band as far as the noise floor in many areas.

Now that is a perfect use case for the wi-fi connectivity option on APX!

One other thing, any idea if GSP will simulcast over their VHF still, or will they go dark.

Heard that the VHF infrastructure will eventually be demobilized. Not sure about simulcast, cutover, anything. We attended a meeting on Confederate Ave months ago about the project. Nothing since.
I have heard stuff along the same line, it has been a fairly tight lipped deal, They weren't necessarily going to abandon the VHF, but they aren't going to maintain it after a year or two. They also plan to interface a gateway between the two, so in theory if the SoCo doesn't work the VHF will, and vise versa.

I was told no to BeON, strictly SoCo's MCPTT app running on the XL's, no multi-sim, essentially the same as what they are using on the sonim devices. (a lot of troopers have mentioned that in our region the SoCo service was terrible)

However I am glad to see a large agency stepping up and embracing new technology (considering Georgia can't afford to build out a statewide trunking network, and the 100+ conventional VHF repeaters throughout the state being a fiasco at best) and possibly abandoning a LMR system completely. This could be a large feather in the cap for SoCo, and could lead smaller agencies to follow suit. I have also heard rumors that AHP will be watching this closely.

Some of the Game Wardens already have the XL portables out in the wild (pun intended) as of a couple weeks ago.

They did price the competition.
The office of budget management folks head spun around like the Exorcist.
They are getting a hell of a deal. L3H wants to make a sale. Hopefully they will pick the right local shops to do the heavy lifting. A project of this size and scope is NOT for "Chuck and a Truck".

Yes, I heard 4 to 5 times as much for the competition. And hopefully L3H will involve the local shops, as they will need the support.

Re-read that, and tell me how that makes sense?
