HC Deb 12 March 1981 vol 1000 c380W
Mr. Wall

asked the Secretary of State for the Home Department if he will consider granting an amnesty to users of 27 MHz AM citizens band radio sets to give them time to change over to 27 MHz FM.

Mr. Raison

No. The evidence of the harm 27 MHz AM transmissions do is so clear that we cannot encourage this by any form of amnesty or lead-in period.
