Default FDNY EMS DB conflict?

The DB lists: 483.20625/167.9 for both Bronx North Dispatch and Brooklyn North Tactical. The same comms can be heard simultaneously. What is the true BK No. Tac frequency?

Right, but the question is what's the correct freq for BROOKLYN N TAC? (I don't have an authoritative copy of the EMS tac channels in my own database, only the dispatch channels, so I can't help).

If that is so, then why is Bronx North Dispatch coming over it loud and clear?

Unless they changed it. This was a mistake and that's how the field radios were setup. How someone didn't pickup on it I don't know.
For the most part the TAC channels are not used.

Looks like it might be a PL incorrect, They use the same frequency over and over around the city
The portables are programmed for 2 watts on the tac channels so on the hip with a speaker mike your getting maybe a watt out if your lucky

Apx. What are you saying is incorrect?

Database is correct.

Even though the frequencies are used many times, I can't believe they would use the same tones. Unless they are far enough apart. Once the right tone is reveled, the issue is solved.

I think tbendick would know since he is OTJ so I would go with what he has said.

Yes, it is.

This anomaly dates back to the Health and Hospitals Corporation days and has gone on ever since. Back in the mid-'80s 477.8625 , 85.4 -simplex - was the only Tac channel citywide (F8), as well as being the Brooklyn South / Staten Island dispatch channel (F5) - repeater. In the late '80s, 477.8625, 85.4 - repeater - became the Brooklyn Central (at one point to become the Brooklyn North for a while) channel, while still remaining F8, the Tac channel - simplex. In the early-'90s, when each borough, more or less, first got it's own Tac channel (usually simplex on the dispatch repeater output), the citywide Tac channel remained the simplex of Brooklyn Central's dispatch repeater. The early to mid-90s brought some major system "improvements" that have come and gone (800 conventional, 800 trunked) and the hostile takeover. After this latest upgrade (the move to the upper T-Band), one would have thought that this oddity would have been fixed. I'm not sure why, to this day, one of the Brooklyn channels still gets recycled elsewhere - with the exact same CTCSS tone.

What happened is that they programmed all the tac channels using one PL tone and recycled the dispatch channels for the use as tac channels. When the new narrowband repeaters where setup they changed the output PL tones after initial configuration. I believe FDNY setup the tacs and DOITT setup the repeaters, so I think this might be where the disconnect occurred.

The tac channels are pretty much never used and almost useless. They would have been better to setup the tacs as simplex of each repeater like the old mx radios had.
