HC Deb 19 June 1975 vol 893 c481W
46. Mr. Litterick

asked the Secretary of State for the Home Department if he is satisfied with the adequacy of the transmission facilities available to B3C Radio Birmingham.

Mr. Alexander W. Lyon

Yes. The medium wave transmission has recently been increased in power, but, as with most medium wave transmissions, the service area is reduced after dark by interference from other stations. VHF transmission, which is the primary service for local radio, provides a more constant signal in this area.
