Interference

Interference

with broadcast reception can be caused by certain kinds of electrical machinery and appliances. It usually produces buzzing or clicking sounds. If your reception is spoilt by noises of this kind, and you are quite sure that your aerial is efficient and that your receiver is not at fault, the GENERAL POST OFFICE will help you to locate the cause and will suggest means of overcoming it. Too often the GPO is asked to help listeners who suffer interference because they haven’t put up effective aerials. Don’t give the GPO engineers unnecessary work, because in such cases they can only recommend your improving your aerial. This is specially important if you live rather far from the nearest BBC station. This advisory service, which is free of charge to wireless-licence holders, can be obtained by application at a main Post Office or to your local GPO Telephone Manager.

will also advise listeners whose reception is disturbed by private transmitting stations or by morse transmissions.
