§ Mr. Warrenasked the Secretary of State for the Home Department whether, as at present proposed, it would be possible for the British Broadcasting Corporation's planned Carfax radio information service for motorists to interfere with foreign-based air and sea navigation systems; and if he will list those which his Department believes could be affected.
§ Mr. RaisonYes. From 1982 the spectrum needed for Carfax will lie partly in a band primarily allocated internationally to the maritime mobile service. Present proposals for Carfax would involve restricting its initial operation so as not to conflict with existing stations abroad. The ways in which a full Carfax system would conflict with prospective maritime use will not be known in detail for several years, after an international conference has planned the stations of the band concerned, but when introduced those stations will be able to displace Carfax, which will have subordinate status in the international radio regulations.
