HC Deb 19 April 1950 vol 474 c19W
Mr. Blackburn

asked the Postmaster-General to what extent the short religious services broadcast to the Soviet Union every Sunday have been jammed; and what steps he is taking to overcome the interference.

Mr. Ness Edwards

The first of these experimental programmes on 12th February was not jammed; subsequent programmes have been subjected to jamming. The B.B.C. is striving to make such transmissions less susceptible to jamming.
