Does anyone know what 2091 ID is on the P25 system. Sounds like the MassPike west. Something new ? Thanks Phil

if you take 2091 and multiply it by 16 you get 33456 which is E Patrol 1 in analog.

Troop E traffic from Interchange 14 west is on E-PTL-1 and traffic from Interchange east is on E-PTL-4. I don't know if you'll hear E-PTL-4 on the P25 system in western MA, but if you see TG 2239 that's E-PTL-4.

The P25 system is starting to become very active, so you'll should hear a lot of traffic from now on.

Does all digital traffic sound the same, as I have noticed this on the CT SP. Is there a way to eliminate this gargled sound? Thanks again Phil

On my psr500 the CSP trunk system sounds much better than any P25 trunk system I've heard. From my understanding the CSP isn't P25 yet although they will make the switch someday. So to answer the question, I would say, no not all digital systems sound the same.

Connecticut State Police is definitely using P25.

The audio is P25 digital, but the control channels are still 3600 baud Type II trunking. At leat for now, but I'd expect that to change at the next system upgrade.

There is no digital mandate by the FCC as of yet. Many analog systems needed to be narrowbanded by the first of the year, which means the radio system must be reprogrammed from 25.00kHz to 12.50kHz. Some agencies rather then doing that switched to P25 which operates in 12.50kHz.

Also Motorola and Harris push for agencies to go P25 because it has a much higher price tag then a analog system.

The new Troop B is P25 trunked. If you cannot hear them, try a search using the preprogrammed Public Safety range. If you don't hear a control channel at 852.9750 (B South - Mt Tom) or 853.6375 (Wilbraham), you are likely out of luck.

So I'm confused. At this point you can hear E-PTL-1 on both trunked analog TG's and trunked P25 TG's? If so, any idea how long they will have both systems? I primarily monitor MSP but haven't invested in a digital scanner yet.

It will be a while. The P25 build out has started in the western part of the state and will gradually move east. Most of the MSP sites are still analog, so that's why you'll hear P25 talk groups on the analog sites. And vice versa.

E-PTL-1 is 33456 analog and 2091 P25. Traffic will be on heard on both systems simultaneously.

For example, if a Turnpike cruiser in the Worcester area is operating on the analog system, that traffic will be repeated on the P25 side out in the western part of the state.

Additionally, Troop B digital traffic will be repeated on the analog Troop C (zone 8) sites.

The same thing is going on in Cambridge as they build their P25 system. Most of the units are still on analog, but some few are on the P25 system.

For completeness sake, I have to mention that there is some digital traffic on the analog sites. That is P25 audio, but the control channels are at 3600 baud. The new sites in western MA are true P25 trunking with 9600 baud control channels and all digital audio.

Confused yet?
