Marine band" VHF radios used on ships and to communicate between vessels and harbours, bridges, locks etc, use frequencies between 156 - 162MHz. Please note that the use of American FRS and GMRS walkie-talkies in the United Kingdom is not legal, and could cause interference to licenced radio users. We have sold and hired radio equipment to thousands of schools and colleges from small primary schools up to large secondary schools, colleges and universities.
