Marcus Communications
What the heck is Marcus Communications? I see they have a bunch of LTR frequencies. Is it worth it to program them into my scanner?

When in doubt, program them. You might be pleasantly surprised.
If you're not happy with what you hear you can always delete.

Marcus Communications also does several town police department systems.
Newington, Windsor, etc...
Bruce Marcus is also on the board of the PVRA amateur radio group.

Most, if not all of the sites have a mix of Passport and regular LTR. The Passport freqs mostly have the key ups every 1-2 seconds where the regular ones have the key ups every 10 seconds. The Passport sites are linked by a statewide microwave system.
I recently saw a license with several frequencies that were being switched to digital. Can't recall which format.
As was mentioned, load up the frequencies and try listening.

Isn't Bruce the guy that sold a bunch of towns LTR (non public safety designed) radio systems for police, fire, and EMS? Also, in some cases he was able to get licenses transferred from the communities name to his own?
I have no idea if that is good info or not. If it is then I assume you will hear a mixture of public safety and commercial radio traffic together regardless of where the frequency falls in the band plan.
I read somewhere that LTR was designed for business users. Not sure about Passport.

The ones I know are below and all 3 are 100% public safety/municipal systems:
Newington - LTR
Windsor - Passport, then changed to LTR
East Windsor - LTR
The commercial side of his systems do carry public safety traffic with the majority being commercial EMS.
Passport and LTR are aimed at business users but some agencies do use it. Passport addresses many of the shortcomings of LTR (but Windsor wasn't happy with it). The systems are less expensive than traditional public safety trunking systems so the bean counters like that part of it.

If it is the Passport side, you can't trunktrack it (at least not easily). If it is the regular LTR system, you would need to first determine the Logical Channel Numbering (or LCN). LTR does not transmit frequency info like most trunking systems but gives channel number which goes to a lookup chart programmed into the radio.
Determining the LCN can be a long process. There are several threads on this site devoted to it.

Chris-
Can Passport and LTR work with simulcast?

It has been a while since I spent any amount of time monitoring LTR systems.
They can share frequencies if the repeaters are programmed to do that (and are capable). Some of Marcus's sites have channels for both. A Passport radio can do LTR but a LTR radio will not necessarily do Passport. As far as simulcast, it is not a subscriber function but a console function.
I know that the various LTR public safety systems have "All Call" talkgroups, so that would allow someone to access multiple TGIDs at once. I believe that would not be a LTR trunking function (reserved TGIDs) but a programming function.
