RADIO NOTES.

ENTERPRISE OF THE R.B.C. SHORT WAVE REBROADCAST. I " The R.B.C. has announced that when the Southern Cross attempts the Tasman flight all stations will be on the air to report progress, and a description will be given of the landing, which will possibly be effected at Christchurch. It must be said to the credit of the company that no opportunity is lost to put on the air any event that is of public interest. In view' of such events of national interest and importance the enterprise of the Radio Broadcasting Company is further show'n in the building of a short-wave receiving station on Mount Victoria overlooking Wellington for the purpose of relaying oversea short-wave broadcasts. Hitherto short-wave reception for rebroadcasting by 2YA, Wellington, has been accomplished in a suburb afflicted with power-line leakages and other sources of interference. The relay line had also to pass through the city, and thence to ?2YA station, a distance of over two miles and a half. A line only a few hundred yards in length can connect the short-wave receiving station with the transmitter at 2YA. When these short-wave rebrosdeasts take place Wellington listeners with crystal sets costing only a few shillings will be able to hear programmes and announcements from stalions hundreds, and even thousands of miles across the seas. AUSTRALIAN STATIONS. The Australian stations are coming in at about their maximum strength these days, and except for static interference are good. Even the weaker “A class" stations, SCL and 7ZL, have been heard at very good volume during the week, while many of the Aussie “B” stations are very loud. Serious interference is being experienced by many listeners on account of the wavelength proximity of 2GB, Sydney, anil 3YA. Even on a fairly selective set a hetrodync whistle is heard, while on some sets the result of tuning in to either station is like an “Irish Parliament.” 'The Japanese stations also clash with several Australian wave-lengths, and render reception “woolly” at times. The programmes from the Japs may be a novelty, hut if such dirges were broadcast for entertainment of New Zealanders it is hard to say what would happen to the broadcasters. The thanks of listeners are due tj the 11.8. G. for the Sunday morning broadcasts of the big football results.

In consequence it has been noticed that owners of sets have become very popular with their neighbours on Sunday mornings. W-’hen connecting your loud-speaker lo the set be sure (unless a filter circuit is used) that its red terminal is joined to the terminal on the set, j which is connected to H.T. positive, i (If this is not done there is risk of serious damage to the loud speaker.) j
