HC Deb 02 December 1936 vol 318 c1244
34. Mr. DAY

asked the Under-Secretary of State for Air whether an international agreement has yet been reached as to the systems and wave lengths to be employed in the use of radio beasons; and how many of these installations are now equipped and available for use in Great Britain?

Sir P. SASSOON

The Telecommunications Convention of 1932 embodied world agreement in respect of certain wave lengths. There exist in addition later agreements between various countries, the terms of which will come under review at the next Telecommunications Convention which is due to meet in 1938. The present number of radio beacon installations in this country of all types, including five under trial, is 10.

Mr. DAY

Have the trials of the systems installed at Croydon been successful?

Sir P. SASSOON

Perhaps the hon. Gentleman will be good enough to put that question down.

Captain HAROLD BALFOUR

Is my right hon. Friend aware that certain internal air lines have been unable to use wireless owing to the statement of the Air Ministry that there are not wave lengths available; and can he give the House the assurance that there are the wave lengths necessary for further development

Sir P. SASSOON

Perhaps my hon. and gallant Friend will put that question down.
