I find it of interest that the Brooklyn RF DTV 16 channels were the first group to switch.

Perhaps a coincidence, however the performance the P25 Vocoder may be an improvement when RF levels increase during tropo on 482-488 MHZ.

Perhaps a consideration for FDNY as well.

The 482.9125 NAC 233 that I reported hearing yesterday was really active starting almost exactly at midnight last night. That is reportedly to be a Manhattan precinct.

Here is the latest I got last night. Again, started just after midnight. Only a few logings, so probably just testing.
484.4125 NAC 749 (PBMN 5)
Looks to me Manhattan will be the next to transition over.

have all the PBBKN zones transitioned to P25?

The move to the encrypted Patrol Boro channels is temporary so that their regular precinct frequencies are readied for the changes. They need to work on the precinct transmitters, multiple receivers and associated links. There will be a period of coverage testing within the precinct areas before the units are moved back. Then it will be the next batch that will be moved for their zones to be readied.

oh. so the current PCT freqs will transition to P25 (retaining the same frequency)? What will happen to the three Patrol Borough P25 freqs?

Spares.
It’s going to take a long time. In the late 90’s they went from 3 Pct’s per zone to 2 in the Bronx. During the transition the precincts would operate on PBBX and a citywide channel. The radio shop would work on the zone then switch them back. That took 2 months to do the Bronx. That was analog replacing the Micor’s with MSF’s/Quantars and adding receivers changing consoles and backhaul equipment. Expect a week or 2 per zone if not more.

The question is will any NYPD frequency remain unencrypted after the p25 upgrade? Will any frequency remain analog? Wondering about SOD and other city-wide frequencies such as citywide one and citywide two, that have other agencies and interop capabilities

Probably not, the assumption is that everything will be P25E. Only time will tell once the transition is complete.

I have the same question with reference to the Tac/Simplex channels that ESU and others use.

No, 73/75 and 77/79 are still clear. Brooklyn south as well.

They are working North to South within each borough, with a maximum of 3 zones at a time. The Patrol Borough channels are temporary while zones undergo "maintenance" (the euphemism for upgrade to P25E). While the upgrades are occurring, an automated recorded message will play on loop similar to this one for Brooklyn North:


Precincts will revert back to their original zones once maintenance/upgrades/testing is complete. The goal is in fact to be fully complete before the ball drops on New Years. To be seen whether it will happen or not.

Has this been confirmed? Haven't heard anything about this.

DCPI has an arrangement with recognized major media.

Yes, Precincts will revert back to their original zones once maintenance/upgrades/testing is complete. The additional Patrol Borough frequencies will likely be retained.

Probably not, the assumption is that everything will be P25E. Only time will tell once the transition is complete.

Everything will be encrypted unless something changes.

So is the long term intention to move back to the original frequencies (with the obvious new NAC and P25E) or are the Patrolborough frequencies the new permanent home?

They will move back to their respective zones and frequencies once the "maintenance" (change over) has been performed on all the hardware for that zone. The Patrol Boroughs are temporary homes until that's done. The same automated recording will play on all zones being changed over in the meantime.

Who do we thank, lil brother?😂

That would be difficult with his move to the other side of the country. And leave people's family out of the discussion please. Seriously your jokes about my brother have gotten reeaaaaally old.

More new updates for me. I am surprised no one else has posted any new freqs heard but continue the comedy on the other closed thread. Maybe no one else on the other thread can hear them, which I would be shocked, seeing I am 70 miles away from the city.
Anyway, the newest of my catches, all E of course so no idea which zone they are going to be. I imagine they are still working on Manhattan.

So far we have northern Brooklyn, northern Manhattan, southern Queens and SI in the process (or soon will be) of switching over to encrypted precincts. Think of precincts that are more likely to have rougher crime being done first.
