RUGBY, September 14.
Major-General G. C. Try on (Postmaster-General) has revealed that after consultations ; with American telephone authorities the Post Office is constructing a special radio receiving station near Rochester" to combat intense sunspot activity which is expected to ■ interfere seriously with world radio communications in 1940. As the Post Office, with the exception of one long wave-length channel to America, operates the whole long-distance international telephony service on a short wavelength, the approaching period of sunspot activity has been viewed with grave concern. The new technique to be employed at the Rochester station, by which it is considered the adverse effects of sunspot activity can be offset to a great extent, is bound up chiefly with the use of a number of receiving aerials suitably spaced in the direction of incoming signals. It is hoped to commence the service early in 1939.
