Saw the Article about the new "Shoulder Radios" on the homepage today,
anyone know if these are just more mobile-extenders linked to the car VHF radios
or an entirely new system?
The 859.4875Mhz frequency is active here in central Morgan County, IF a Trooper
vehicle is close. It seems to repeat all VHF traffic on whatever channel the car radio
is set to.

Shoulder radios?? My guess would be that the Troopers are getting HTs with public safety speaker mikes (the ones that have the antenna on top) as well as additional mobile extenders for the vehicles. It also says that they are building more towers and apparently getting amplifiers for the mobile radios in the cars.

With DPS wanting to implement a digital VHF trunked system (my conclusion based upon press releases and conversations) I wonder if this new equipment is a stop-gap solution until the new system is implemented, or a realization that its going to take much longer to implement the new system then they had thought?

Troopers to get shoulder radios

GINNY MacDONALD
News staff writer

Alabama state troopers are getting 400 shoulder radios aimed at eliminating transmission problems around the state and letting troopers communicate more quickly.

Now, if a trooper leaves his car, he loses his means to communicate by radio. Shoulder radios and other new transmission equipment will give troopers that means.

Radios are expected to be in operation by the end of October, thanks to a $3 million grant from federal Department of Homeland Security. The first 50 radios are being programmed at the trooper communications shop in Montgomery. They should be in operation in northwestern Alabama by the end of October, said Alabama Department of Public Safety Director Mike Coppage.

The grant also will be used to build towers for the radio system and buy signal amplifiers for patrol cars. Coppage said there are more radio towers in north than south Alabama.

"It will allow us to let a trooper get out of a car and transmit. We don't have anything like that now, and the trooper has to fight his way back to the car," Coppage said.

Some troopers have SouthernLINC communications equipment, which they bought themselves.

Two years ago, then-DPS Director Jim Alexander described the state troopers as having the poorest communications system in the nation. Thirty-five percent of the troopers across the state cannot talk to their posts, especially those in rural areas, he said.

With the towers and new base stations, troopers are projecting 95 percent coverage of the state.

The radios will mount on the shoulder, have a lapel microphone and not be handheld.

859.4875 is the most likely the extender frequency. These M/A Comm radios will be used on the current system and will be compatable with any future system.

Thank's for the info, I thought the article was talking about mobile-extenders and not the VHF
digital system we have heard about in the past, but this is Alabama. Remember the Statewide
EDACS 800Mhz system? We all know how that went!

*****Alabama state troopers are getting 400 shoulder radios.......*****

Why not transmission hump radios or spare tire shelf radios? Come on guys/gals. They are getting P7100 EDACS radios with speaker microphones (lapel mics; shoulder mics or whatever you want to call them). P7100....that is a portable (handheld).

I like "transmission hump radios". I'm going to have to use that one to see what kind of looks I get :)

When the story first came out, I did a Google search for "shoulder radio" on the off chance that it was some sort of new radio equipment that I hadn't heard of. I got back quite a few hits, including legal documents that referenced law enforcement shoulder radios. My guess is that its some sort of police slang.

So is the EDACS system going to be going to be used for these new radios?
It's dead here in Morgan County as far as DPS talkgroups go, Everything is
VHF conventional & Southern-Linc iDEN.

I suspect that those HTs will have the 859.4875Mhz mobile extender frequency programmed in, as well as the 800Mhz NSPAC frequencies.

I've heard a Trooper using the Montgomery City-County EDACS system (not a patch) to communicate with the Montgomery County SO's dispatcher. I don't know if these HTs can do trunking or conventional with the flip of a switch, but if they can, I think that local EDACS trunked systems will be programmed in as well.

Take a look at the DPS talkgroups on the Gadsden EDACS system. You could see some of them show up on other EDACS systems.
