§ Mr. Wallasked the Secretary of State for the Home Department what is the estimated cost of an open channel handheld set on 928 MHz as compared to a similar set operating on 41 MHz.
§ Mr. RaisonWe have no information on which to base a precise estimate. We recognise that 928 MHz equipment would be more expensive, but equipment cost is only one factor in determining the choice of frequency for open channel radio.
§ Mr. Wallasked the Secretary of State for the Home Department what reply he has sent to the letter from the chairman of the National Council for Civil Defence about the use of open channel radio in a post-nuclear attack period.
Mr. BritianThe chairman of the National Council for Civil Defence was told that no account had yet been taken of the possible contribution of open channel radio to wartime communica- 637W tions. We shall, however, be considering the matter.
§ Mr. Wallasked the Secretary of State for the Home Department how many replies he has received about the consultative document on open channel radio in favour of frequencies of 900, 41, 230 and 27 MHz, respectively.
§ Mr. RaisonA full analysis of the responses to date to the discussion document on open channel radio is not available, but a large majority favour 27 MHz.
