NYC's new UHF systems

A lot of testing of the conventional and trunk parts of this UHF system. Felix and the boys are maning the remote sites and 11 Metro Tech's 4th & 5th floors. Testing all the componets with Moto and FDNY people on site. Several of the conventional channels were IDed during voting system tests in S. I. The use of the term "MRD" has me stumped, any idears out there?

 

[ff026]

what frequencies where you hearing conventional(non trunked) traffic on? i only have the trunking system in my scanner.

 

[newsnick175]

Check out www.n2nov.net and find his list of future fire UHFs. He has them listed by boro with their PL tones.

FDNY Testing Now on UHF 482.23125

Finally hearing some testing on this freq as of 1:22pm
I have it marked as Citywide

Why is it that every time there is activity with FDNY or Doitt UHF new threads start. I used the search feature this site offers and found 6 threads on this topic already.

alot of chatter today as they are testing comms.also heard a digital talkgroup so it may come live real soon?!!

 

[DaveNF2G]

Depends on what you mean by "real soon." Usually the radio shop will get the base sites functioning properly, then install mobile radios. Installation for an agency the size of FDNY will take a long time.

 

[PJH]

Actually, the bulk of work is already done.

 

[FDNY216]

Is the everday FDNY dispatch and Everyday ems primary dispatch channels on the conventional freq going to be P 25 or analog???

 

[SCANdal]

401,

FDNY*EMS dispatch channels are already conventional UHF analog.

A very active day of testing. Three field teams calling in with grid and boro locators. "Dispatch" is responding on both analog TG-6176 and digital TG-48128. 48068 and 48080 are the other active digital TGs. Analog TGs are active in the 6100s. There has been no digital activity on the conventional frequencies. Start saving your $ for that new digital scanner this Christmas, you'll need it!

 

[bezking]

Folks, please keep all activity for this system within this thread.

Thanks!

If the term is still used properly, MRD stands for Mobile Radio District. A term that came out of the LEAA radio programs of the 70's.

 

[newsnick175]

My mistake. Its "EMD" that was used to ID some of the channels. Any way testing seems to follow a pattern. "Team 2" calls in with a grid location on an analog freq for a 5x5, after they are acknowledged, they switch to an analog trunk channel and then a digital one [48128] to give the grid a passing grade. They then move on to another grid. There appear to be 3 ground teams and a marine unit ["boat team"].

I fully expect to find a complete run down of the system [both conventional and trunk] on the n2nov.net site in short order.

I'm in lower Manhattan and am picking up this system on my RS Pro-106. The analog TGs are coming in very well. However, the digital TG (48128) is coming in uncoded--just the digital noise one would hear on a non-digital scanner. In the settings, I have the system type as "MOT VHF/UHF." Should I be using the P25 Auto setting instead? All conventional P25 signals are being read well on my radio.

i cant get my 796 to go into trunking mode on this system, im picking up the control channel with 2 bars but the scanner wont trunk, it just scans it normaly. i tried using the settings from the database but the scanner wont take the 6.25 channel spacing. anyone have any idea's? i updated the firmware on the 796, and tried searching all of the forums

 

[dave3825]

Is the scanner capable of 6.25 spacing?

 

[ICP114]

Conventional

is the conventional system for dispatch going to be definitely analog or digital

 

[K2KOH]

MRD is Municipal Radio Dispatch, also known as the statewide mutual aid frequency for NYS
