WIRELESS NOTES.

v • ' '\ Should it be necessary to disconnect -.{ all the battery leads from a set, discon- '; nect their ends from the batteries, be- ; fore taking them oft' the terminals on','; the set. . ■;, ##* # # J When overhauling your earth con- '» nection remember that just as the "< strength of a chain is that of its weak- ', est link, so is the efficiency of <an earth"-;, connection largely determined by uw '/• soldered joint of the earth wire. i ' # * # # * If you experiment with reaction control when the local station is on, not ,i only do you interfere with other peo- '-' pie's programmes, but the powerful , transmission of the local station pre- '- vents you from hearing the exact effect of the freaction increase. Always , choose non-broadcasting hours for such . tests. . # # * ' * # \ The most conuhon cause of low-fre-quency howling is a run-down H.T. battery. When a' dry battery begins to get old its resistance increases rapidly, and its voltage falls. Both of these ~■ factors, particularly the former, tend -,' to give rise to distortion. , # # H> # * • _ '■; With the taking over of SCL, Ade- ,'j laide, on January' 14, and 4QG, Bris- - > bane, on January 30, all the "A" class :, stations in the Commonwealth will be •'" welded into one control and co-opera- ■ tion and co-ordination of programmes •: will be possible. An elaborate system, v' of relays will take place, and by the ," time there is a unification of all "A" class stations the new*-type of radio ".< programmes will be in full force. Victoria is first in the field with the new radio presentation. The huge licence increase in that State for the month of October is attributed to the fact that the novel presentation and unit enter-**' tainment supplied by 3LQ and 3AR have been responsible for the big increase in licenses. The entertainment is now spreading to New South Wales and Western Australia, and soon South Australia and Queensland will have joined the fold, and there will.be general contentment among wireless set owners throughout the Commonwealth. # # # * * The day of the stereotyped concert programme of broadcasting is dead. '■ Dead as the proverbial, door nail. The listening public requires a background for its broadcasting fare, a background capable of supplying vision when only sound is available.. This may'read like double Dutch, but it isn't. It's a true .. statement. Imagine 300,000 homes in which the radio is installed, and mulfciply that by three to find the number of listeners, and you will find that nearly one million people are clamouring for interesting broadcasting programmes away from "the stiff and formal programmes puresented to the public since . . broadcasting's inception. Like every modern invention, radio is also, clam- _ ouring for a change in environment — ' environment that .will give it individuality and originality. The Australian Broadcasting Company has found _ a solution to the problem, and having found it will put it into operation. Listeners will be pleased to know that they will hear Cec. Morrison'a band on the air more often in future. Cec. Morrison is a very popular broadcasting personality, and his band is voted as "one of the best." ■ Besides other appearances.Cec. Morrison's band will take charge of the dinner hour music on an average of twice a week from 2FC and 2BL, and it is his intention to make it as bright and informal a session as possible. Each member of the band will be called upon to entertain listeners with solos on their respective .instruments. Cec, (Morrison will show listeners just what he can do with the piano. Novelties will be ineluded in the dinner hour'.session such as "The Cat's Whisker and his Eight . Valves." This will introduce the high-frequency valve stepping up on the saxophone, the power valve making sharp noises on the sousaphone, and so on. Cec. Morrison will be only too pleased for listeners to write in for their request numbers. He has- an extensive library, and can musically cater for all and sundry.
