RADIO PROGRESS Every year, indeed every few months, is seen some new example of the steady progress which radio investigators and manufacturers are making. Evidence of this was apparent at the British Royal Air Force display at Hendon, held in July, which was such a magnificent air spectacle and which attracted such a huge concourse of people. The daring and intricate evolutions carried out by pilots participating in this great air meeting would have been liardly understood by many of those present but for the wireless arrangements made to ensure that everyone was kept informed of the nature and progress of each event. Marconiphones were installed, and nearly sixty powerful loud-speakers were employed. Five special 32valve power “banks” comprised the last amplifying stage for this equipment, the total number used being nearly ISO. The energy for this immense sys-' tem was provided by a motor generator giving 350 volts and accumulators aggregating 2,000 volts. The total high tension current was 6,000 millianiperes at 350 volts, approximately equal to a consumption of 2,000 ordinary three-valve receivers. Over 350 amperes at six volts were taken for the low-tension and loudspeaker fields, being more than 2,100 times the energy required by the three-valve set. This power plant alone weighed nearly four tons. Twelve miles of buried heavy armoured cable was laid for conveying the amplified speech and music to 30 loud-speaker positions round the airdrome, and the Installation contributed very largely to the enjoyment and Interest of this great display. WOULD YOU LIKE IT? A complete wireless station is for sale. This station is built on one of the Seychelle Islands, in the heart of the Indian Ocean. It was built during the war for the Navy, but as the Admiralty no longer requires it the Governor of Seychelle has invited tenders from anybody who wants to buy it en bloc.
