Radio Round the World

HE Government of Imxemburg has just granted the monopoly’ of broadeasting to a company for twentyfive years. Provision is made for the establishment:of a station with a minimum power of 100 kilowatts in the antenna. ‘It is to be situated ten miles from the capital, Work on the station‘ is to be commenced immediately, an~ it is expected to extend over eighteen months. In the meantime a temporary station with a power between six and eight kilowatts will be opened. © = * z QNE of the results of the Prague plan to contidl Buropean: broadcasting has. been the improved stability of the frequency of transmitting stations. "World Radio" regularly ' publishes charts showing how the wavelengths of every station in Europe varies. These are computed in Brussels, and show the slightest variation in transmitting frequencies. "Betiveen October, 1929, and April, 1930,. the number of transmitters with more than a kilocycle error have been rediced from 14 to 9 per cent. Every station receives immediately notificar tion if its frequency is ineorrect. * x e "THE series of air disasters is having a great effect upon public opinion, says a French journal, and is. forcing: Governments to look into the conditions governing aviation. In ‘this re-: spect the Government is to be approached on the subject of the presént in-~ security brought about by. ineffective . radio installation. It appears, indeed, that the state of the material employed. ym military and commercial airplanes is altogether defective, and it is a very real danger to both aviators and passengers. Far from securing protection, radio, under these conditions, augments the risk. The journal urges that an inquiry should be made in the near future to look into this grave source of danger. ¥ Me HEN a German amateur cannot eliminate his radio trouble it is sufficient for him to send a postcard to the district representative of the Radiophonie Society and a technician is on the spot. That is not at all bad, but another company goes one better. In the contract entered into when one takes out a license the Reich Society has foreseen cases where their technicians damage the receiving sets accidentally. If this happens, the damage is made good to the set-owner by the eompany. Ld bd * "THE German station at Nauen has _ just been experimenting successfully with television. . On a wavelength of 70 metres pictures were trans-

mitted to a neighbouring town at the rate of 20 per second, which corresponds to a transmission. of 50,000 photographie points per second. The people photographed in the transmitting studi, were recognisable at the point, and one could follow ‘their moyement as on a film fifteen centimetres square. Nevertheless, working on systems now in use, it. will be many years before television can be of, any practica. use and ean, with radio, enter the home. : * 8 ‘THE year 1929 has been, in the Union : ef. the Soviet Republic, the first where radio has been used systematically for instructive purposes. In the ‘U.S.S.R. ‘sixty. thousand pupils are regularly: instructed. Of these, twentyeight thousand are to-be found in Mos~ cow.. The instruction has been extended to the Universities, called "Workers and Peasants," where the "workers" are employed to teach special courses. Six thousand pupils learn. by radio from these institutions. A, technical q ecurse’ for metal workers has 8,206 listeners, a course for agriculture 1000, . the teaching profession 6500. Among the pupils for ‘University ¢curses, 25 ‘per cert. are soldiers of the Red Army..... bd Ed e NEw- ‘Zealand listeners, especially ... those troubled. with'-interference, _ will: be interested in the following clause contained in Jugo-Slavia’s new... penal code: "Whoever, voluntarily or by -~ negligence, prevents or interferes with the functions of a radio installation by means: of electrical installations, or who interferes with or misapproprigtes — the current necessary to the working of a radio installation, will be punished -in the event of a disturbance or stoppage taking place-by one year’s imprisonment or-a fine of 10,000 dinars (approximately £394)." ~ fr,
