Coast Guard P-25 UHF Nets

I received a report from the Southeast US that the Coast Guard has started utilizing some frequencies in the 406-420 MHz band for its operations.

413.0000 MHz, P-25 (NAC not reported but I suspect N293) was heard in use by Coast Guard Sector Charleston along with 2 MH-65C helicopters.

They referred to this as "CG-410", which makes some sense in the new NTIA naming schemes. The other CG P25 net channels all start with 1, such as NET 101, since they are all in the VHF band and the frequencies start with 1. The 400 MHz channel frequencies all start with 4, so the NET numbers will apparently start with 4 as well.

I have not heard of any routine use of the federal UHF band by the Coast Guard, but there have been some vague references to new UHF radios for CG cutters and law enforcement use. Keep watching this band for more Coast Guard operations. Here are some known UHF allocations for the US Coast Guard:
