side, is on tli© air on Wednesdays, Thursdays and Sai.urtla.ys with good programmes, the modulation of thi .-> station being particularly good. HEARD IN THE TRAIN. The well-known French amateur experimenter, M. Meuars, while travelling in a train, was able to pick up Australian and American stations. The experimenter was using a twovalve set, without an aerial, merely making connection with the electric light bulb of th© train. For a distance of nearly forty miles these stations were audible. **** BREAKFAST RADIO. Broadcasting before breakfast is common in U.S.A., and several stations run a physical jerks programme at. 7 a.m. each day. Uhlv one station in Australia is doing this—2l3L —and a number of energetic young enthusiasts rise at a few minutes to seven in time for these morning "jerks." U has been suggested that the idea be extended and that footballers and other athletes take advantage of the innovation. A good story is told in connection. with the "broadcasting before breakfast" craze in America. —already mentioned in this column. A listener wrote, telling the instructor how much be enjoyed hearing about his strenuous exercises cold-water douches etc. whilst he, the writer, was lying in his warm bed. The instructor politely ' replied, informing his correspondent how much he enjoyed giving tho lessons whilst he, also, reclined in bed. ** * # FOCAL AMATEUR TRANSMISSIONS. ' Some successful communication on about 40 metres with distant amateur transmitters ha s been carried out recently by Mr.; Russell White, of IAO, (writes ''Thermion" of th© N.Z. Herald), using the small, input of 22 watts. During the past 10 days twoway communication has been carried out!with 47 different American amateuife from all except two, of the radio districts into which the United States is divided. The transmitter at IAO is made up by using the. Hartley circuit; loosely, coupled to a vertical aerial 22ft, long, used in conjunction with a 1 single-wire horizontal counterpoiso of the .same length. The .'receiving set is of the low-loss type, consisting of detector with a single stage of audiofrequency amplification, the Hartley circuit bring again used. Listeningin. with Mr White at lour o'clock oh Sunday afternoon, the writer picked up a uuinher pf amateurs sending from, the eastern, side of the United State-, the volume of the signals on 40 metres being rather astonishing considering the comparatively low p'jweia u.sed at the transmitting stations. Mr White', is in constant touch with Lieutenant F. H. Schnell, traffic manager of the American Radio Relay league, who is carrying out, at the request of th- '-teed States Navy, special,: experiments on short-wave work during the manoeuvres of the American fleet in the Pacific.
