Is it me or is the rest of the MTA Police very quiet on this system? I only hear Dists 1/2 which is the Island, and I'm up in Putnam. I get the fire brigade as well. Thanks~

Which simulcast site are you listening to? Westchester? If you are able to hear the NYC Simulcast site, you will hear all of the districts (except D-8 in Ct.) as well as NYC talkgroups and NY State PD ect..

I hear them speaking a lot, like pro said are you sure you're listening to the correct simulcasts? Once and a while I will hear Connecticut all the way down in Brooklyn

I'm listening to two sites, actually Zone 2 and Zone 7. No where near the Island. One is Southern Dutchess and the other site is in Mahopac. Weird

In the last 20 minutes, all I see on 9650 is one radio id, and it has keyed up 30 times and its the only rid seen on that tg.

That’s like an everyday occurrence up there.
Not really. It can be silent for long periods. Sometimes I tend to think it’s switched off! Or should I say, not connected to the network? Getting full signal. But very little traffic.

When a radio (subscriber) comes up on a talkgroup at a site, it has affiliated. Basically the subscriber is telling the system "Hey I'm here at Site X, and I want to listen to TG Y", at which point the system will start broadcasting that TG's radio traffic at that site. If the subscriber de-affiliates and there are no other subscribers at that site on that TG, the traffic is no longer carried.

There are exceptions to this rule, but they require the system admin to force traffic to be carried regardless of subscriber affiliation (or lack thereof) and are not commonly done.

So the bottom line is that if there are no radios requesting talkgroups at your local site, there won't be anything to listen to. The system is operating normally, and the site is not "disconnected" from the rest of the system.

Thank you for your explanation.

For counties in the northern Hudson valley without p25 radio infrastructure built I assume radios would translation to using LTE. Am I right?

Since MTAPD already uses LTE on subway patrols on a daily basis. I would say the capability is definitely there and well demonstrated. I think the limiting factor is a lot of Upstate New York (is Dutchess/Putnam) are quite rural and LTE coverage is also spotty

As well as keeping GPS and Bluetooth on 😑 Of course when I ask my buddy who’s an MTA Police officer what he thinks of the Harris radios; himself and literally everyone he knows in his district complains batteries die too quickly
