Mr. Flynn

To ask the Secretary of State for Defence what information he has on the purpose of the powerful microwave transmission from the Soviet Union beamed at the United Kingdom.

Mr. Archie Hamilton

I have no information on powerful microwave transmissions from the Soviet Union beamed at the United Kingdom.

Mr. Flynn

To ask the Secretary of State for Defence whether there has been any change in the past five years in the microwave transmission intensity radiated to the United Kingdom from the Soviet Union and known as the woodpecker signal.

Mr. Archie Hamilton

I have no information on microwave transmissions radiated to the United Kingdom from the Soviet Union. "Woodpecker" is a high frequency over-the-horizon radar transmission to which there has been no change over the last five years.
