§ Mr. H. Clarkasked the Postmaster-General under whose authority non-broadcasting stations operate in the medium-wave broadcasting band; and whether agreement to operate such stations was obtained from the international broadcasting authorities.
§ Mr. BevinsThe band of frequencies from 525 to 1605 kilocycles per second is allocated on an internationally agreed basis to the medium wave broadcasting services. The use of a frequency for the operation of a non-broadcasting station in this band in the United Kingdom requires Government authority. International agreement to operate such a station would not be required unless interference would be caused to the services of another Administration.
117W
§ Mr. H. Clarkasked the Postmaster-General how many non-broadcasting stations are transmitting in the medium-wave broadcasting band in the United Kingdom; and if he will state the nature of these stations, the power of the transmitters, and the frequencies on which they operate.
§ Mr. BevinsIn the United Kingdom there are seven non-broadcasting stations which have been assigned frequencies in the medium-wave broadcasting band. All of them are concerned with aeronautical radionavigation and their powers range from 3 watts to 25 watts. The frequencies on which they operate are 534, 543.5, 597.5, 669.5, 723.5, 732.5 and 797 kilocycles per second.
§ Mr. H. Clarkasked the Postmaster-General what steps he is taking to have the medium-wave broadcasting band cleared for its proper function.
§ Mr. BevinsThe presence of a non-broadcasting usage in the medium-wave broadcasting band is kept under periodic review. Having regard to the very low power, and the frequencies used, there is no possibility to my knowledge of interference with the reception of B.B.C. stations or with the reception in the United Kingdom of Continental broadcasting stations.
