Can any one tell me if the rs 197 will work on the new system. thanks

Here are the specs.:

https://wiki.radioreference.com/index.php/Pro-197

"The Radio Shack PRO-197 is a Digital Trunk Tracking scanner which has the ability to track APCO 25 digital trunking systems, in addition to following Motorola type I/II systems, LTR and EDACS trunking systems. It is very similar to the GRE PSR-600. "

If they are going to be using Phase 2, no the Pro 197 will not work.

Can any one tell me if the rs 197 will work on the new system. thanks

Chris,

Question about something you said a few posts ago. The current 800 system is not simulcast?? I though it was, as a radio in eastern CT could be received in the middle of the state if a subscriber is affiliated in that area ??

How will the 700 differ, from the 800 as far as simulcast. I always assumed a radio in Troop E area would automatically simulcast on that troops 3 towers, and anywhere else in the state if there was an affiliated radio in that area.

Nbc news just ran a story tonight on the 11pm news on the system and they said coventry, stonington, groton and norwich will go to that system

Here is alink to that story Towns and Cities Weigh Benefits of Regional Radio System
The story says access to the sytem is free? just BYOR ?

It seems to be a good deal for the towns.

The current system, like the new one, has a mix of simulcast and standalone (the old Motorola name was Intellipeater).

The system is free... for now. Should the State (all of us) pay for all the upgrades down the road that benefit these towns or should the towns chip in? Perhaps fund it like MA is doing with increased fees on the 911 "tax" on phones.
The towns get a system that was designed to cover 95 percent of the state with mobile radios. A new tower had to be added to improve Groton/Stonington coverage. I believe that was a town expense.
They tested in here Granby. Horrible coverage, even in mobiles. If the town were to spend the money on a couple new towers or add the SW700/800 infrastructure to existing towers in town, it would be a very expensive proposal and would be cheaper to add a simulcast voting conventional system.

any one know if the state police are going to use the phase 2 system.

What sites are currently simulcast, and which are standalone.

 

[cg]

Current system, Sites 1-9 are simulcast, 10-18 are standalone. P25 system, likely that 21-31 will be simulcast, above that will be standalone. The Cell numbers could change when they changeover, that will be obvious when it happens.

I'm in range of the Plymouth and Wolcott sites here in Woodbury. If there's anything I can do to scan for new TG's or frequncies for when Troop L is added let me know. I have my SDS100 running ProScan. Seems L is the last to get it. I havent done much for discovery, just mostly scanning. I'm wondering where the Troop L site will be located.

I can get A on the 800mhz system, and A on CSERN as well from my location, as well as Troop L on the 800mhz system.

 

[cg]

The lack of 700MHz licenses for B, D, K, & L would lead me to believe that those Cells will use the existing 800MHz frequencies and simply switch to P25. Troop K has one of the early 700MHz sites however, I suspect that will be a standalone cell for the Colchester area.

Interesting article on NBC regarding the new SP system. I'm all for Statewide infrastructure and each townships only contribute to access fees and subscribers.

One comment that I wasn't sure is right is towards the end where the guy says we have unlimited bandwidth. How is that possible? Each cell or zone in the system typically has a control channel and then 4 or 5 voice frequencies available. If you start putting local services on the system, doesn't that increase the odds of a user finding no frequencies available when he PTTs? Or is this system different from the old one? Still trying to understand the differences and why the state had to abandon its 20 year old digital 800 MHz statewide system.

 

[cg]

The old Motorola system was analog control channel, digital voice channels, 1 conversation per frequency. The new system is full digital. However, the big difference is that the new system is P25 Phase 2. This means the voice channels can handle two simultaneous voice calls. This is called Time Division Multiple Access or TDMA. With this, the channels alternate very rapidly, each using the 12.5KHz bandwidth. The end result is that a Cell like Troop H with 6 frequencies available can have 10 conversations going at the same time (1 frequency for the Control Channel and 5(x2) for voice).
The new P25 system is backwards to P25 Phase 1 but not to the Motorola system. All radios need to be P25. I believe they will require all to be Phase 2 for efficiency.

So my BCD325P2, SDS100, and HomePatrol II will be able to deal with that then. Of the three, the HPII seems to struggle the most with the newer systems, though it is marketed as being Phase 1 & 2 capable.

It was quiet yesterday and today

 

[mkt853]

What's the difference between standalone and a cell?

 

[cg]

Cells are several sites that are simulcasting on the same frequencies. A Standalone is a single site with separate frequencies usually to address a small area with poor coverage. They are usually very limited on the traffic they carry and may have as few as 3 frequencies.
Troop A actually has one in NY. Troop B has 2, L has 2, I has 1, G has 1, H has 1, and K has 1

I just got a used uniden 986xt last week. How much longer will it be before it's obsolete with regards to CSP?
