New DEA UHF - UPDATE!

I recently received some information on another new UHF channel associated with the DEA transition to P-25.

412.5750 MHz, N156 has been heard in use in Mississippi as a simplex air-to-ground channel.

UPDATE!

I just received information that there is a new DEA repeater on 406.6000 MHz, N156. It is located in southern Mississippi, specific location unknown as of now.

The DEA list on the top of the blog home page has been updated with this new information.

New York City FIO2

For a while now, I had confirmed that 171.1750 MHz, N653 was officially designated as NYC Federal Interop 2. However, I had never heard anyone using it.

But when I arrived in town this last week, I heard a couple of days of traffic from some group moving around the NYC area. They were a large enough group that they had to take separate ferries when they were using the Staten Island ferry. It sounded like some sort of escort. The only call sign I caught was "1A7", so no idea what agency it was. I did also hear "Topside" a couple of times, but not sure if it was a call sign or just telling someone where they were on the ferry!

Boston Area Mystery Aircraft

Many media outlets are carrying stories about Boston area residents being disturbed by low-altitude, "mysterious" aircraft at all hours. Here is one such story:

Officially, the FBI and Boston officials are not confirming anything about these flights, but anyone checking the aircraft N numbers, or paying attention to federal radio traffic in the area are pretty likely to figure this one out...
