NOTES AND NEWS. Wairoa Broadcast*?. Idly twisting the dials after 2YA finished its afternoon session yesterday, dropped on a fairly strong and quite clear transmission on about 305 metres: A description of a hockey game was in progress, and, as this was somewhat unusual, held on until the closing announcement at 5.15. This did not come through as distinctly as did the relay, and sounded like 2ZB or 2ZC, VVairoa. .Modulation was good and reception was very steady. Other Stations Heard. Another good relay was carried out by 3YA. IYA, Auckland, was heard at good strength. So was 4YA, Dunedin, which also exhibited fine steadiness. 2FC, Sydney’s relay was good—a high-class concert by the Liedert'afel. Radio Society. At to-night's meeting of the Christchurch Kadio Society (198 A, St Asaph Street, eight o'clock! the principal speaker for the evening will ho Mr L. Gerity. fie will describe and demonstrate an A.C. operated short-wave receiver.^ 2UW "Hocks In*'. A note from ''lnsulator” tc band this morning states: ”1 was just getting off to bed last night when T happened on 2UW on 31 metres, who was simply rocking in—miles ami miles better than the other night. It was fine on the speaker—test match progress reports. Modulation was excellent. Time was 10.40.” Reaction Condensers. Remember that there are two very different types used in modern receivers. There is the quite ordinary variety. Which is really only a normal variable, such as is used for tuning, of the appropriate capacity. Then there is the "differential”, which is quite different. This has three terminals joined to threes sets of vanes, two of which are fixed. But not all variable condensers having three terminals are necessarily of differential design. This is :in important point. No other kind of condenser will do the work of a differential in the special differential reaction arrangement ~ A reaction condenser does not need as tine an.adjustment as a tuning condenser, so a slow-' motion control is not a necessity. S.O. in Short Wavers. "I am still more convinced, after a fortnight's listening (during bad conditions) with my stage of tuned screen odgrid R.F.. that it is very definitely worth using. As far as sheer ‘bruteforce.’ amplification goes it is quite equal to an extra audio-magnifier, while it docs not bring up the background noises in the wav that an A.lf. stage, usually does. And 1 am also sure that signals that on a detector and A.F. are too weak to be readable, or even audible, are brought into the range of one’s receiver if a good screened-stage is used."-—S.W.L., in "Popular Wireless”.

of the air?” asks an English visitor to rj.S.A., and answers himself thus: They most certainly do. For instance, a railway put on a series of programmes in which the central point was a sketch showing the pioneering work done in the making of the great transcontinental line. The artist who was engaged to plav the chief part in these sketches made a great success. At the conclusion of the series, the railway company offered him a free journey right across the continent ill a special coac-h. It aeveloped Into a triumphal procession. At every wayside station, at every smtui citv, the train was stopped. Mayors turned out with their hands to welcome the actor and present him with the freedom of the city, mothers brought him their children to bless, and named them after him, crowds lined the streets and applauded and cheered. The man had become a great thing in their lives and they took the only method they could of showing tlieir appreciation.” A Hovel “Stunt". Munich’s new series of outside broadMunlch’s new series of otuside broadcasts took place at noon on June 26, when the. "radio reporter” went to have Ids watch repaired. Wo heard him ask questions about.wliat really was wrong with it. and the watchmaker answered in easily understood language. We learned quite a lot about watches and their most common ailments. The broadcast lasted exactly fifteen minutes, and the striking of clocks and the playing of a tiny musical box heightened the acoustic effect. The next broadcast of tliis type which is planned will take the “radio reporter” to a department store, where he will buy glass jars for jam and for preserving fruit. Housewives will eagerly listen to this, as. of course, now is the time for preserving fruit and making jam, and a guide is really needed to the various new types of jam jars and preserve glasses.
