More Coast Guard UHF Activity!

More reports have come in regarding the Coast Guard's Short Range Communications Upgrade System or SRCU.

P-25 digital communications have been heard in the San Diego area on 416.5500 MHz, N293. And just received word that 412.9750 MHz, N293 has been active in the San Francisco Bay area. The 416.5500 MHz frequency was not identifed by a NET number, but apparently the 412.9750 MHz frequency is known as NET 409. Reports are that NET 409 was patched to NET 113 (163.1375 MHz) and 164.9000 MHz was heard active with the same radio.

I have included a listing of previously known Coast Guard UHF allocations and identified the current P-25 channels that are known. Keep searching for new allocations to possibly pop up.

Oh, and the photo is the USCG tower in Kelso, Washington, with two VHF and one UHF land mobile antenna on board.
