Freq. 857.71250 - trying to locate in Radio Reference Unication Import Window

[D31245]

I set up a knob position to Free Scan: 763-870 MHz and landed on 857.71250 which had a lot of voice traffic - seemed like southern Massachusetts. Heard reference to Attleboro and Rt. 24.

Doing a search in RR, the frequency is associated as a P25T control channel for Williamsburg (Berkshire Hills - I am in Leominster) but I think it was more the Mass State Police Metro Boston Simulcast? Is it an MSP Conventional frequency?

I am trying to program it into my radio but cannot locate it for import. Closest I could find was the State police conventional frequency tables but it is not in there. Not sure I am on the right track. Appreciate any help.

Why not just program it in manually?

Thanks @phask. I didn’t have a problem locating it in the RR DB (see my search result above), but rather, locating it in the import window from the Unication PPS (software).

If you are hearing it on FREE SCAN in the pager then it would not be a control channel you are hearing, it would be a voice channel, Free Scan does not stop and decode P25 control channels.

Were you able to get it programmed in?

Not yet. Not at my PC at the moment. Will try again tomorrow or over the weekend. I haven’t tried to enter manually yet. Will use that as a last resort.

Yup, Zone 5 is the Voice Channel you are hearing.

Being adjacent to Zone 3, some of the D-PTL-x TG's will be heard on 5 which is also known as the A/H Zone

It ;looks to be the 3rd selection in your first screen shot, as Metro Boston Simulcast

Keep in mind it is only 1 Voice channel from a potential list of 9 others

 

[D31245]

Thanks at @RaleighGuy and @ecps92. Trying to figure out how to locate those frequencies in the Unication PPS. I’ll keep on digging. 👍

@ecps92, besides 857.7125, are the other 9 Voice channels the ones on this list (including the control channels)? Or other frequencies?

The reason you can't find it with Unication is because (in theory) the G Series pagers do NOT support TYPE II systems, you can manually program in TYPE II frequencies and use them as a conventional digital P25 frequency or, if analog, a conventional analog frequency, but they can not be programmed through the RRDB import feature because they aren't supported by the pager. You can manually program in all the voice channels as conventional P25 (or analog if not digital) and scan through them, but true trunking is not available. I do this for a federal prison near me that is still using a Type II system.

Ok 👍 thanks @RaleighGuy. I would have never figured that out.

There’s so much nuance to programming these pagers but it’s an enjoyable learning curve. Really appreciate the insight!

Success!

Just an update: I was able to manually program in the 857.7125 frequency plus a few others from the MSP Central Mass Simulcast page (those in black below). After manually adding the frequencies I wanted, I had to add each one to a knob position, then build a scan list in a new knob using Normal Scan mode:


After running a scan, most of the voice traffic is on 854.4125. I will play with this a little more and see if I can get more coverage. But so far, lot's of voice traffic from many areas of the state (early rollover about 5:20AM Rt. 95N and around the same time, heard a reference to Rt. 169 MA/CT). Am very happy to get this programmed in. Thanks for all the help everyone!

Scan list so far:

• 857.7125 (5% of voice traffic)
• 854.4125 (95% of voice traffic)
• 854.4875 (no voice traffic yet)
• 854.7375 (no voice traffic yet)
• 856.2375 (no voice traffic yet)
• 857.2375 (no voice traffic yet)

Correct the 0d14 portion of the MSP and Analog network
Altho they have some paths (voice channels) that can do both Analog and P25 Voice - the network is the legacy

What is your exact QTH to best direct you to possible Phase I/II sites nearer

Thanks @ecps92. I am in Leominster. Maindenhead grid square: FN42cm

I set up a knob position to Free Scan: 763-870 MHz

The one thing I haven't done with my G5 yet. That's a great catch!

So for the Phase I/II you are not going to get any MSP from your QTH

You might get the Worcester site, but that is/was built out for Worcester and very likely carries ZERO MSP Traffic

99.99% of C-Troop, A-Troop, H-Troop and D-Troop are Analog on the 3600 0d14 analog TRS
Till the completion of the Phase I/II build out (years from now) you will likely be Analog
Only B-Troop is (mostly) built out

You’re pretty much spot-on @ecps92. I have the Worcester P25T site programmed into the radio and get a lot of the Worcester talk groups but no MSP.

My radio goes in and out of range on occasion and hoping when they build out the system, they add some antennas in my area because it looks pretty sparse.

• 857.2375 (no voice traffic yet)

Listening to the voice channels when the system gets busy is going to be difficult to follow conversations, 854.4125 which is C simul Channel 2 is the most busy because its the first available voice path, but as the site gets more traffic the other voice channels will fill in. Channel 3 and Channel 8 iirc are ASTRO capable and typically carry the digital TGs on the system such as Franklin county, Orange PD and Shelburne control.

There are no MSP TGs being carried on worcester simul besides LPS, statewide, tech channels and occasionally SOPS depending on affiliation. The worcester system is built out and wont be expanding, what you see is what you get now.

as Nik indicates each of those Non State Phase I/II sites were built for a specific user, vs MSP

a. Worcester and the towns neighboring who joined
b. Cambridge
c. Massport

The exception is the 700 overlay, but rarely is MSP heard, unless they are directed to use the Digital Zone (ie: Brookline for the major Golf tournament a few years ago, or something specific for the Marathon)
