169.6000 MHz NYC

I've received some reports of a mystery P-25 frequency active in the New York City area.

169.6000 MHz, NAC 169 was first reported as being a patched simulcast of the Federal Protective Service UHF channel, 417.2000 MHz. I was first wondering if this might be the reason some FPS vehicles have been seen with VHF antennas on them.

But further reports have come in that say this frequency has been heard repeating various NYPD Citywide channels and Newark NJ PD channels as well.

The frequency itself has been used by many different federal agencies, including the Department of Agriculture, US Coast Guard, Customs and Department of Energy, to name a few. It's unknown who is using this frequency for what purpose, but further monitoring may give us a clue.
