Anybody have any idea if NCPD is upgrading their /\/\ Sabers when they move to the 500 MHz system? If so, is it known which radios?
Nassau County 500 MHz Radios

I bet you Nassau doesn't even know what radios they are going to go with yet!

They'll be going with the XTS. It is the only Motorola model line that supports P25 Smartzone. My understanding is that a final decision has not been made regarding which model.
The Systems Sabers will have to be retired eventually since the split is only 458-490 MHz and while they support Smartnet, they do not support Smartzone. Even though both are type II trunking, the control channel information is different on Smartzone. You could, concievably use a Smartnet radio on a Smartzone system if the Smartzone system was setup with a single zone. Then no roaming information would have to be handled. The new Nassau system, however, will be a two zone system out of the gate.
(Even thought the bandsplits on the Systems Sabers really blow, the radio specs are terrific!)

I wouldn't hold my breathe waiting for the 500 mhz system, it's been in planning since 2004
I don't think that is going to help you at all.bezking said:
If Memory serves me correctly, they are moving to an MA/Com technology that can not be scanned yet..
My question is, if I purchase a MA/Com HT off of ebay, will I be able to monitor, or will all radios need to "handshake" with the server to allow it to receive?

It could certainly be another year before transmitters are online. A digital scanner would be necessary ultimately. Initially, I would expect the first talkgroups to be cross-patched to the corresponding analog channels. That buys a little more time from having to get a digital scanner. In the next year or two the price of digital scanners might come down a bit.
The system is Motorola P25 Smartzone, not M/A-COM. The system has already shipped to a warehouse here. I would not expect encryption to be used on a regular basis; just for sensitive operations.
Once installed, it should be great!

Knowing Nassau--it's a definite maybe kind of
The system will have TGs for every emergency service organization in Nassau. It will be the "one radio" access to all emergency comms for anyone to talk to anyone else in the county.

scosgt,
Trouble hearing the 2nd and 8th ??
I don't know if it's the system or not but all I heard today (Tues 5/22) was complaints on the Nassau PD radio of poor reception no matter what channel I scanned.

You gotta wonder why they need to use up 500 MHz frequencies when the FCC gave 'that side' of the Hudson exclusive use of Channel 16 (482 - 488 MHz). That's 240 12.5 kHz wide exclusive channel pairs. In my mind, channel 19 (500 - 506 MHz) should have stayed exclusively on the west side of the Hudson. But what do I know?!crashcrew said:

If you take a closer look at the TV16 band, you'll see that the vast majority of the bandwidth is licensed to agencies in NYC. NCPD has use of five channels (I think its five) which are currently used for mobile data. Narrowbanding the current NCPD channels in TV16 will not be enough, not to mention what would come of the units needing the lost data coverage. It is a physical impossibility for NCPD to use the narrowband channels in between the wideband assignments licensed to NYC.
This is not really debatable because the NCPD had to prove to the FCC that there were no other available channels in any band before they could be issued a waiver to operate in TV19 (500-506).
The reality is that with NYC not using any bandwidth in TV19, it is quite possible for agencies in Nassau County sharing the airwaves with New Jersey. I do not know of any problems between agencies on Long Island and NJ--currently--regarding the use of TV19. And, you know what the most interesting part of this is? Since all of the TV19 licenses in NY and northern NJ are on waivers, they were all exempt from frequency coordination (APCO, IMSA, etc.) yet it all seems to work.
My suggestion is NOT that coordinators are not needed. They are. I am implying that they could have done a better job in the bands that they do coordinate.

I thought NYC's implementation on 16 was 11K2, I see your point about adjacent channel issues with 20K0. You'da figured that the FCC would have required 11K2 right from the initial implementation.CloroxCowboy said:
That should be a simple search. There is literally someone on and adjacent to everything (in other words, don't even submit an application unless it has all of the LOCs from co and adjacents attached).
Most of the NJ systems were designed around small AOPs and implemented "right-sized" instead of over-ERP to cover their communities. This was a big departure from VHF and the 453/ 460 legacies. To my knowledge, I can't see most NJ Ch. 19-based system's 21 dBu contour extending past the Queens/ Nassau border. There may be one channel on Fort Lee high-rise. The rest are relatively low HAAT.
My concern was that over HAAT or over ERP systems (500W ERP and a claim of 40 kmra AOP for a 1 square mile town) would box-in everyone. It would be the same on both sides of the river. As long as everyone is responsible and not embellishing like they did on VHF, things should be fine. Anyway, the more population served the merrier, especially when the Media Bureau decides its going to assign 19 to some HDTV within ducting distance without checking on the waivers the WTB or PSHSB issued.
Well, even though it's not "coordinated," the processors still receive the application, chances are that the one who did the search justification for no frequencies available was a coordinator or local advisor and someone still has to do an engineering study. You can't send that directly to the Commission or enter it ULS without going through one of the coordinators (I could be wrong, but I don't think so... I haven't dealt with T-band since Form 574's). My only direct filings have been on 700 (we have that out here), 4.9 and DSRC.
Hey - I enjoyed your perspective!

Thank you for the very thoughtful feedback. Actually, according to the FCC decision from 1995 that permitted temporary use of TV16 around NYC, APCO asked that the Commission require 12.5 spacing, but the City of New York asked for 25. Obviously, we can see what was handed down. If you want a printed excerpt, send me a PM.
