RADIO RESISTORS

USE IN MANY DEVICES ■Willie it may be true that radio borrowed many devices from other Helds in the early days of improvisation, today radio is lending many of its own devices to other Helds. Quite recently the precision variable resistors developed for radio purposes have found important applications in other directions, even in the handling of real power, which is perhaps the highest recommendation that can come to any variable resistor. The most important non-,radio application of radio variable resistors is n o£ ?? otor speed control. 7Y° C fi? t y ' such ra dio variable resistors as the power clarostat, and also the heavy-duty clarostat, have been adopted for the speed control of small picture* harticulariy for small motion stat wPth° JeCt ° r - S ' l The P° wer claroscat, with special asbestos Dackine withstand '"thT . in ® Ulatins washers, to in handing‘u e p To e ßo e^« a s oTl" control°for U sold XtenSiVe USe as a haa t devices rn ‘ f' ,n “ i rons and other work variJL ®^ ph and tele Phone bl ° resistors of this kind of n fhT X 6nSlv ? a PPlication beme trie °r es?stor T?

The work of the performexcellent, but the Scottish play was hardly suitable for broadcasting, d’u l ?u fact dialect dialogues do not lend themselves to broadcast T as . lt; , ls to ° difficult to follow. Lroadcast plays should be given fov performers with clear voices if tho words are to be easily understood.

Frank Sanger, the announcer, said he was closing down,at 12.17 a.m. Eastern nTw \ n ear.

It is quite likely that a similar relay may be arranged from Whangarei. Listeners will welcome the news that the radio dealers are trying to bring about an agreement between the Auckland City Council and the Radio Broadcasting Company, so that the Auckland Municipal Band can be heard over the air again. It is to be hoped that negotiations will prove successful as the band was easily the most popular item on tire Listening to the announcer giving the race results during the holidays 0f| e , realised the difficulties under which he was carrying out his work. Ho did his best under tho circumstances, and those who could not be present at the races had much to thank him for. At tho same time bare results are not very interesting and it is to be hoped that the racing authorities will soon see their way to allow broadcasts to be made as formerly. If they stick to their former decision, perhaps the broadcasting company could get over its difficulties by securing a high tower wagon, similar to that used by tho tramway department. From this they might be able to view the races well enough to describe them well. ♦ * * After a delay of several months, until the photoradio apparatus of the U.S.S. Texas could be modified to meet new changes in speed, tests between the Navy Department and the Texas have been resumed. Experiments have been conducted daily with gratifying results, the fsavy Department reports, the most interesting and important of which is the transmission of the daily weather map from the department to the Texas at sea. This noon weather map is rushed to the Navy Department by messenger, where it is turned over to the photographic section of the Hydrographic Office, where a negative film is prepared for the photoradio operator by 2 p.m. It is then transmitted to the Texas. That very entertaining pair, the Asquiths, were heard from IYA during tho week. Their turn is a good one, and is always appreciated by listeners. A more frequent appearance before the “mike" would be welcome.
