Barry, You may be able to use this in a WIA broadcast. 73, Richard VK7RO From the Listener In, 14th March, 1925. The Launceston Radio Experimenters' Club made a name for itself last Saturday when the Henley-on-Tamar regatta was carried out by means of wireless. A speed boat was fitted with an efficient wireless telephony apparatus which conveyed the results of races etc., to a giant loud speaker stationed on the regatta ground. In this way the results were made known to thousands of spectators who were unable to see the finish of the races in true perspective. Quite a number of the boats participating in the regatta were fitted with wireless, so that it was possible for the yachtsmen to communicate with their friends during the course of a race."
