I am curious if anyone is hearing any law enforcement activity on 164.9625 MHz in your area. This frequency has been a long used Customs tac frequency that folks in South Florida have been hearing for years. In the old Customs channel plan, this was often referred to as "A-7", and under the new DHS channel plan it may be known as TAC 21. It appears to be used primarily by the Customs Air Marine Division and was very active at the recent Super Bowl in Miami.
What I am curious about is if anyone outside of South Florida has heard the use of this channel. This frequency is not an exclusive DHS Customs assignement, so I'm curious if it is used anywhere else. If you hear any activity on this frequency in your area, please let us know at the Fed Files!
UPDATE - Here is what readers have sent me so far:
