NYPD Citywide Frequencies

[ansky]

Does anyone know why there are separate Staten Island citywide frequencies? For example, there is Citywide 1 and also Staten Island Citywide 1. What is the difference? I'm listening tonight and what I'm hearing on Staten Island Citywide 3 has nothing to do with Staten Island. They are talking about crowd control on First and Second Avenues. I also just heard the Staten Island Traffic Division frequency and there was an officer checking in from the Brooklyn Bridge.

They are separate freqs because they need to cover SI. That's all. It just has to do with RF propagation, nothing to do with the actual content.

Thanks. So it's basically a Staten Island simulcast of the main citywide frequencies.

That's correct. The signals from the "main" repeaters of the channels could not cover the Borough of Staten Island adequately due to topography and were deemed important enough that a multicast (to be technically accurate) was set up to insure true citywide coverage.

Citywide 1, 2, and 3, SOD, Traffic, Citywide IO 1 and 2.

Other citywide channels (e.g.: Detective 2, OCCB1) were not projected to have enough demand / need to be worthy of the expense and technology involved to get such treatment for one borough.

Citywide IO 1 and 2?
The only IO that was multicast was CWIO (w/ no 1 or 2 designation). It is now called NYMAC 1.

Please correct me if I'm wrong...

New York Metropolitan Advisory Committee (NYMAC) 1: 482.6875, 110.9 aka Citywide Interoperability 1
NYMAC1: 482.3875, 110.9 aka CW IO 1 - SI

NYMAC2: 482.7125, 123.0 aka Regionwide IO (formerly Manhattan IO)

NYMAC3: 482.8125, 167.9 aka CW IO 2 (formerly Queens IO)
NYMAC3: 482.5375, 167.9 aka CW IO 2 - SI

NYMAC4: 482.7375, 136.5 (formerly Bronx IO)

NYMAC5: 482.7875, 151.4 (formerly Brooklyn IO)

NYMAC6: 482.8375, 186.2 (formerly Staten Island IO - North)
NYMAC6: 482.5375, 186.2 (formerly SI IO - South)

Edit: Just read N2NOV's reply to another thread. The borough based designators were rendered obsolete in 2010. The frequencies listed above are to be referred to by their NYMAC numbers or, in the cases of NYMAC1, 2, or 3, by their assigned function (either CWIO1 or 2 or RW). In other words, NYMAC5 can be designed for use at an event in any of the boroughs, not just Brooklyn, as needed.

I just heard a dispatcher on 482.8125 identify the frequency as "Patrol Borough Queens." Could this have been a simulcast of 470.9375?

2 questions,

Who operates on citywide 3? it sounds like traffic cops?

also, will the UHF transit channels ever be used? or are they going to stick to the VHF system?

CW 3 is usually "temporarily" assigned to Traffic Bureau, but it's also used for special details during special events and emergencies.

The future of the UHF transit channels is less clear. Original plan was to use UHF above ground, and the VHF system below ground, but, AFAIK no one actually uses the UHF system. They are linked to the dispatchers, and multicast the dispatcher audio (but not the talk-in audio) across bands.
