# Searching For New/Unknown DOITT Talkgroups

Listening this morning turned up the following:
8288 (800 system) = 518 (P25 system) [FDNY 6A ADMIN]
8304 (800 system) = 519 (P25 system) [FDNY 6B OPS]
9584 (800 system) = 599 (P25 system)
11808 (800 system) = 738 (P25 system)
13696 (800 system) = 856 (P25 system) [NURSING HOME CH. 2]
33216 (800 system) = 2076 (P25 system) [ACS FACILITIES]

Also heard on 800 system was TG 48496 digital voice
Are you stating that you heard all of those talkgroups on the P25 system? Or did you simply convert the SmartZone TGID to the P25 equivalent for reference?

I actually heard keyups and digital voices.

What is the 6B ops channel used for?

On both systems? Same activity for matching talkgroups? If you heard them on P25, which cell, UHF or 7/800?

Basically anything, you'll typically hear marine units and marine battalion talking for incidents on the water, I have heard batt. chiefs speaking to marine battalion on it too.

7/800 SIMULCAST

7/800 SIMULCAST
Interesting, thanks for the report. I can receive the UHF cell, but not 7/800, so I'm only getting half the picture.

I have a strange one this morning on the P25 system. TG 644 shows up on both the UHF and the 7/800 cells. I can not tell if it is a specific radio ID that captures one cell vs the other as I am using my Uniden BCD396T handheld.

TG 644, 645 has always been heard on both UHF and 7/800 Cells, sometimes the same radio ID and sometimes with different radio IDs, makes me to believe they have a mix of UHF and 700 MHz radios with common talkgroup.

Do you think TG 644 is Department of Investigation? They are one of the first user on the P25 system many years ago.

Or more likely APX 8000 that can function on either cell. Keep in mind with a P25 system like this, the frequency bands are largely irrelevant as far as the system itself is concerned. Any talkgroup, if permitted to do so, can come up on any RF site regardless of frequency.

#### n2nov

The following unknowns on the P25 system have been heard over the past week:
599 (7/800 cell) <---- definitely mentioning bodies and body bags
618 (7/800 cell)
644 (UHF & 7/800 cells)
645 (UHF cell)
738 (7/800 cell)
1050 (UHF & 7/800 cells)

CUNY Public Safety just popped up on P25 system on TG 950 using 7/800 cell with daily roll call.

Think this is either Medical Examiner 1 or 2 (probably 1 since that's the only one I've heard speaking on the 800 mhz)

#### n2nov

TG 850 on P25 doing radio checks and then bleed-through possibly 13600 (ACS) on the 800 system.
Also TG 1102 on P25 which could be 17632 (Commissioner ALERT) on the 800 system. Both heard on the 7/800 cell.

TG 850 just identified as ACS Police. DOITT radio tech did radio test with an ACS officer.

Picking up TG 40928 on UHF, sounds encrypted. Could be one of the division secure TGs

#### GTR8000

##### NYS Database Guy
40928 is FDNY Division 7 Secure

TG 519 is definitely FIRE CH. 6B OPERATIONS, same as 5664 on the UHF system. But for some reason sometimes I only hear one side of the conversation.
