German Radio

Interesting Exhibition Attracts Much Attention

(THE Olympic Radio Exhibition is not the only herald of the northern season. The Germans have organised their fifth wireless exhibition, which has earned the praises of the guests assembled in Berlin for the meeting of the International Wireless Union. Generally speaking, it was a display by the broadcasting authorities rather than by the manufacturers. The impression of a casual visitor writing to an HWnglish wireless magazine is that although multi-valve sets were still much in evidence, there has not been the effort in this direction that there was last year. The crystal set has, of course, not disappeared. Loudspeakers were again mostly of the cone type, though horn speakers were still in evidence. The Germans have given great attention to the problem of battery elimination, but in this are stil] behind the English and Americans. That radio has become more popular can be gauged from the fact that this year’s exhibition is much larger than that of previous years. Twice as much floor space as was used last year was required.

Interesting Exhibitions. MONG the exhibitions is’ one that has created more than passing interest. Two fully-equipped studios depict the progress made by the broadcasting authorities since their inauguration in 1923. They are reproductions of the old and modern studios. Near to it was an amusing little tableau of a postman emptying out of his bag a half-million or so letters received by the organisation since its foundation. All the uppermost letters, it is stated, were recognisable by their senders. | Another little pile of letters attracted great attention; it was those received from critics. Among these was one from a: gentleman who asked whether they had never heard of classic music, of Wagner and Beethoven ; from another who inquired when they were going to have some dance music, and from a third who applied for a loan of 2000 reichmarks (£100) for a seaside trip to restore his nerves, which were shattered by their ‘wretched catermanling." This exhibit was one of the minor sensations of the exhibition, and created much well-de-served amusement,

HE most interesting of the exhibits is the one including a memorial exhibition of the earlier appliances of the great German pioneer, Heinrich Ilertz. The widow of the inventor visited the exhibition at the invitation of the broadcasting authorities, and a little ceremonial reception was held. . An exhibit which aroused ‘general attention was that of the police. This is the first year they have exhibited. A large. map of Germany fitted with glow lamps showed where the police have their broadcasting stations. In addition to their main 5 k.w. station in Berlin, they have twenty-five transmitting stations of 800 watts and over fifty of 25 watts. The apparatus which tunes a receiving set in the suburbs from the Police Presidency was also shown. AX OTHER very popular feature was a speaking film, shown thrice daily. This gives in a rapid suc: cession of speaking pictures glimpses of the widely separated and diversified towns-which are the headquarters of Germany’s broadcasting stations, as well as glimpses of the stations them: selves, their work and their workers, Systems of picture transmission, ine eluding that adopted by the British Broadcasting Corporation, which, in: cidentally, commenced picture broad: easting last week, are also shown, Altogether 370 firms exhibited at the show,
