Originally Sudbury was a B group transmitter but in order to accommodate the digital transmissions it went E group then, at its 700MHz clearance in August 2018, it ended up a K group (or wideband). However, most B group, E group and wideband aerials will continue to work fine on it.

This includes cities and towns such as Ipswich, Chelmsford, Colchester, Southend, Clacton-on-Sea and Haverhill. Signals can also be received as far as north Kent.
This transmitter has 8 local relays: Burnham-on-Crouch, Clacton, Felixstowe, Ipswich Stoke, Rouncefall (Ashingdon, Essex), Somersham, Wivenhoe Park, and Woodbridge.
