WORLD'S AIR WAVES.

CONTROL . FROM GENEVA.

PROPOSAL OF . CONVENTION. TWO CLASSES OF STATIONS. By Telegraph—Press Association— Copyright. (Received 5.5 p.m.) g un . LONDON. March 30. The International Radiophone Convention at Geneva proposes to rule the world's air waves, says the Evening News. It proceeds to outline a new approved scheme for the redistribution' of wave 1 -igths. The scheme includes the division of all stations into two classes. The first class will provide exclusive wave lengths for high-power stations, with a guarantee that they will be clear of interference throughout the world. For this purpose at least, one wave length will be allotted to each country. The second class of stations will provide non-exclusive wave lengths for low-power or relay stations, which will receive wave lengths on which it has been proved that several widely-separated stations may, by mutual heterodyning, work without interfering with local listeners. The scheme disregards wave lengths of less than 200 metres. It reserves the exclusive wave lengths for countries where broadcasting is still undeveloped. The convention insists on the adoption of a common method of ensuring that each station will rigidly adhere to its allotted wave length. It is expected that Britain will lose one or more of her main stations. The exclusive stations will be at London and Daventrv.
