Testing on radio tech tg right now. Testers on Long Island at various stations. Keep hearing them say they are on site id 21. Also hearing them saying site id 15. Don't see a site 15 listed on the web or in the neighbors list other than the site nac. Keep hearing ox15 in addition to rssi values.. apx (moto) and xl200 (harris) radios being tested I assume as that's what they keep saying they are on. Seems like they are comparing rssi values between the two...
Also, what is the difference between zones and districts?
Thanks

Look at the Site ID in both DEC and HEX, that will answer your question.
The APX and XL200 display values differently. Motorola likes to use DEC values, and apparently Harris likes to use HEX. 21 DEC = 15 HEX.
The Zones are the radio coverage areas, as listed in the RRDB for each simulcast cell. The Districts are the coverage areas for the MTAPD. Go look at the thread on RR, I posted the list of Districts last night.
PS - The system is actually being used, at least for Districts 6/7 and reportedly District 2 as well...not just testing. |

This brings up the questions - now that this system is more or less fully on the air will they just abandon most or all of their talkgroups on Metro25?
And will they continue to just use the state licensed freqs and not the MTA licensed 700mhz freqs such as WQOZ552, WQOZ555, WQOZ581, etc or will those be for another system?

I’m getting “full bars” on this system on my Uniden 396XT and I haven’t heard a single thing all day. Scanner on ID search. Did this go P2?

I don't believe that the MRRS has reliable coverage into NYC, which the Metro25 system obviously does. The two systems are interfaced via ISSI, and so it's pretty seamless to the end user...just select a talkgroup and off you go. My assumption is that the MTA users in NYC are going to remain on Metro25, and outside the city the MRRS sites will be used. Really though, the only way to know for certain will be for users to carefully monitor both systems going forward, and of course in addition to listening to the audio, tracking the systems in Unitrunker or DSD+ is also helpful in sorting it out.
As far as the FCC licenses are concerned, they scrapped the plan to incorporate any 800 MHz frequencies as part of this system, and canceled all of their YE licenses three years ago.
The 700 MHz SY licenses I believe all had a construction deadline of 12/31/2019, which of course has come and gone. I expect that either those licenses will be canceled by the MTA soon, otherwise the FCC will terminate them automatically within the next month or so.

It has been a Phase II system since the day it was built. |

Really? I was picking up transmissions on this system a couple months ago on the Uniden. Oh well, time to break out the PRO-668.
Thanks. |

I should clarify...the Metro25 talkgroups may come over as FDMA (since that's what they are on the Metro25 system), but the new MTA talkgroups native to the MRRS are TDMA. |

Gotcha, thanks. I’ll start using the PRO-668 anyway just so I don’t miss anything.

I dont get why they would bother licensing a bunch of freqs if they were just going to cancel them anyway
Seems like a waste
There are also some 700mhz trunk licenses under NYCTA (WQYA816 WQZT573 WQZT575) but those could possibly be for the future bus system...
