So far no change has.been made in broadcast procedure from the station. A development in the matter of control is possible at the meeting of the Broadcasting Board in Wellington today. state of affairs exists in regard to 2ZW, Wellington, which has also been taken over by the Government. DEMONSTRATING SETS Radio sets installed for demonstration purposes for longer than seven ■ days require a licence to be taken out. The magistrate, Mr. H. P. Lawry, and the radio inspector, Mr. T. Gates, emphasised this point in Christchurch last week when 34 • defendants were before the Court. One defendant stated that he understood it could be arranged for demonstration sets to be kept for longer than so veu del vs. 4t r lo show how much I knew about it," he told the Court, " I wrote to the broadcasting station and asked them to send out a message on my little girl's birthday. Thev would know straight away that I did not have a licence." He added that he did not have a set at the present time as he had been waiting to see how he got on in Court. The inspector stated that even if a dealer had several different kinds of sets he was expected, under the regulations, to demonstrate them .within seven days. It was not permissible for him to demonstrate each make of set for seven days.

ULTRA-SHORT-WAVE? RADIO

What promises to be the most efficient known type of transmitter for ultra-short-wave radio has been constructed for the English Radio Research Hoard. Described as being essentially a radio valve "turned inside out, the new transmitter, it is claimed, will have a longer life, give stronger signals, and provide a larger range of wave-lengths than known existing types. The new transmitter is designed to produce wave-lengths of one metre or less, and to the casual observer its most striking feature is that the aerial literally runs straight through the centre of the valve. The filament, which usually occupies the centre, becomes a ring of, wires surrounding the aerial, and it is j the rapid passage of electrons back and forth between these surrounding wires some Hundreds of million times a second from •* which the wireless frequeneies are derived. An interesting feature of the transmitter is that its design was based entirely on untried theoretical considerations. A small model has now, however, fully realised expectations, and a valve of a size big enough for transmissions up to tho greatest distances possible with ultra-short-waves is shortly to be produced*. The -new valve should he of special interest to military authorities, with a view to short-distance communication in the field. Its chief value from this point of view lies in the relative case with which frequencies can be changed over a considerable range, a point, of great importance where secrecy is involved and many channels of communication may be desirable. Other qualities of the transmitter which are being studied represent its suitability for television. Measurements are being made of its ease of modulation —the process of imposing sound or " vision " frequencies on the carried wave. While this process is an essen--1 tial of any form of radio communication, it presents greater difficulties in television, and the results of tests of this kind will be awaited with considerable interest. As is well-known, one of the greatest practical problems with which television is confronted is that of securing an adequate wave-band m the present crowded state of the ether. This would be entirely overcome if ultra-short-waves were • used, since a practicable wave-band is represented in their case by only a minute range of wave-lengths.

ON ALL WAVE-LENGTHS

Unccfisored political talks are to be broadcast by the British Broadcasting Corporation. Hitherto, politicians been subject to definite limitations, laid down by the 8.8.C., when airing their views over tho wireless. The new series begin on October 12 and will continue each Monday evening. About a score of M.i . s and other politicians will take part. Those who have promised to speak include Mr. Mac Donald, Mr. Lansbury, Air. Baldwin, Sir Herbert Samuel, Mr. Arthur Greenwood, Sir Stafford Cripps and Air. J. H. Thomas. The only restriction placed on them will be that of time. Mr. Lloyd George, Mr. Winston Churchill and Sir Aiisten Chamberlain, as reported in a' cablegram in the Herald on Tuesday, have protested against their omission from the broadcasts.

' Nearly 1000 radio licences have been taken out in the Gisborne district, which includes the' area between Motu and Morere as well as the coast. Jhe increase during the past 1/ months has been remarkable. In or adverse economic conditions radio dealers were kept busy, no fewer than •>•'o new licences being taken out in that tune. Licences issued to the end of March, 1932, totalled 638. A year later the figure stood at 833, and an indication that there was no waning of popularity in radio was that a further 100 licences were added during/tho following live months, bringing tho total at tho end of August to 988. Licences are still being issued, and the 1000 mark should be reached very soon, if the present rato of issue is maintained.
