GERMANY'S LATEST

WORLD'S GREATEST STATION. Germany’s new 120,000 watt broadcasting station, said to be the most powerful in the world, was opened for service on, December 20. With an aerial current of twenty-two amperes, all parts of the globe should be able to hear the new Zeesen Station, which is operating on a,wave length of 1250 metres, according to electrical engineers in Berlin. The station is ote of Germany’s outstanding engineering feats of the year, The masts are nearly 700 feet high and support a five-strand aerial 920 feet long. The transmitters ate three-phase, high frequency, and operate ten and twenty thousand watt valves. In the last phase there are six water-cooled valves of twenty thousand watts each, connected in parallel, giving a total of 120 thousand watts. THE COOLING SYSTEM. A cooling system with a surface of *300 square yards uses about 4000 gallons of- water. In addition tlgere is an air-cooling system with an exhaust of 50,000 cubic yards hourly. Zeesen is connected with several other German broadcast stations by wire, enabling the same programme to be broadcast simultaneously without appreciable loss. Concerts and other programimes from Berlin are cartied by | wire a distance of fifteen miles to Zeesen. SYSTEM OF EARTHING. One feature which has given to the station special efficiency, engineers assert, is the system of earthing, which is obtained with a gigantic finely woven net of copper mesh buried forty feet under the surface. Germany desired to possess the world's greatest broadcast station to permit Germans throughout the world to enjoy in their native tongue -music and lectures, and in addition to obtain the interest of all the nations of the world in the fatherland.
