RADIO TRANSMISSION

NEW PRINCIPLE INVENTED WAVE-BAND EXTENDED An entirely new and revolutionary principle in radio transmission lias been demonstrated to a gathering of radio engineers in London by Dr. Robinson, late chief of the Wireless Research Department of the Air Ministry. This new device is embodied in an instrument about eight inches square, and has the effect of making it possible to multiply indefinitely the number of stations receivable in any given wave hand. In existing circumstances, it is not possible to receive more than 110 stations on wave-lengths between 200 and 600 metres, or more than 16 on wave-lengths between 1,000 and 2,000 metres, without cross interference. This new and revolutionary principal in radio, if it does all that is claimed for it, will solve the ether

congestion question. It will also greatly increase the speed of telegraphic signalling (up to 10,000 words a minute), and will make television commercially practicable. Dr. Robinson, the inventor, also states that howls from neighbours, and interferences of all kinds, will become a thing of the past; the telegraphing of unlimited pictures will be facilitated; the cost of telegraphy and telephony will be greatly reduced; and 10 times the amount of traffic will be able to be carried over the existing telegraph and telephone lines. Dr. Robinson, whose position in the wireless world is high, has called his new device the stenode radiostat system of radio communication. The source from which the information comes suggests that probably some reliance can be placed upon it. The inventor also states that the device will not be sold as a separate radio unit, but manufacturers will be invited to incorporate it in the sets they build.
