Brian. Try 773.93125. Remember it's transmitted in p25 so you won't hear the data stream unless you force the scanner to analog.

I'm at the Salem 4 corners and can maybe hear data but not enough to be sure. Can someone confirm the control channels are correct? I thought I read somewhere that the order they are in makes a difference, is that so? Thanks for all

Troop D & K are not online yet for P25. Troop E is what you have.
You don't want any of the Motorola CCs in the list until they are switched over to P25.
Try 773.33125 as that is the Colchester P25 700 site and looks to be the closest P25 signal. It has been active for years and probably has a bit more traffic on it now. It may become a fill in site for that area when the P25 goes live.

Most of the second part of the posted list is going to be inaccurate on the new system. Most everybody will have 6 or 7 digit IDs. The new APX radios have appeared as 1xxx and 2xxx for mobiles and 6xxx for portables. There are a few of the old 1xxx and 3xxx radios left but they should be gone fairly soon.

Since this is a system in transition, don't worry too much about the 4 digit IDs. The CSP ones are going to be "reused" by adding 180 to the beginning where others like DEEP or local Constables will change completely.

If you are monitoring the P25 system when someone talks on the 4.1 system, you see the current 4 digit ID. If you are monitoring the 4.1 system when a call originates on the P25 system, you see ID 65520 (reserved ID) since the 4.1 cannot handle RIDs over 65535. If you are monitoring the P25 site and there is a radio on the P25 system that is active, you should see 180xxxx (for CSP)

Example:
Troop H's only municipal patrol area with a Resident Trooper is East Granby. You have a CSP Trooper and local Constables employed by the town. The Trooper might now have a Mobile radio of 2345 and a portable of 6789. There are two ways you can see the radio. First, if the trooper is affiliated and transmitting on the Motorola 4.1 system (old CSP), the radio ID is the 4 digit ID, 2345. If the radio affilates on the P25 system, that radio uses 1802345 (180=CSP, 2=mobile, 345=individual radio).

So the East Granby Tax Town Code is 040. The mobiles on P25 will be 401005 (40=East Granby, 1=mobile, 005=individual ID

See?, clear as mud.

So 1xxx, 2xxx, and 3xxx are mobiles, and 4xxx,5xxx,6xxx are portables? That makes sense based on monitoring however the state's website shows the opposite?

Yeah, haven't figured that one out. They are consistent with doing the reverse. Also the Groton radios are reversed as well.

No, 773.33125 is the control channel for the existing (old) Troop K 700MHz trunked site. That was an answer to someone else's question about coverage.

Often when one municipality changes and improves the system they are using, others realize what crap they had been working with and want to get those benefits themselves. No different than buying a new car. Clean, shiny, everything works, if there is a problem, someone else fixes it.
