FLORIDA CITY OPENS LARGEST RADIO STATION Hialeah Rant Costs SBOO,000 —Operation Requires 250,000 Watts. Bu NBA Service MIAMI, Sept. 21.—The largest high-power radio station in the United States has just opened at Hialeah, a suburb of Miami, Fla. The total combined power required to operate the transmitters is in excess of 250,000 watts. The cost of the station is approximately SBOO,OOO. Provision is made for receiving fifteen messages on fifteen different radio circuits simultaneously. The station is multiplex, so that all transmitters and all receivers car be operated at one time. Republic- Linked This huge station is the latest development in the work of the Tropical Radio Telegraph Company in linking together the United States with sister republics in Central and South America and will have an enormous influence In promoting commerce and diplomatic relations In the Americas. With this station the Tropical Radio Company has two high-power radio centrals in the United States in direct communication with Central America, and Colombia. It is planned to have two circuits available for each country, thus insuring immediate communication. The Tropical Radio Company is 3 subsidiary of the United Fruit Company, which has today over 100 oneway radio circuits in operation Ijbetween the United States and Central America and between Central America and the West Indies. Because of the shrinkage all guys should be made of rope.

LIMITS FOR HIGH POWER ARE SHOWN Government Radio Engineers, After Investigations, Say Experiment to Overcome Static Doesn’t Pay.

Bu tiKA. Service WASHINGTON, Sept. 21.—Conclusions drawn by government radio engineers, studying the effects of super power on the ills of radio broadcasting, point to the belief that super power doesn't pay. Tests of 50-kilowatt broadcasting as against that on 2500 watts, from station WGY at Schenectady, end reports from many points throughout the country, reveal these facts: 1. High power hasn’t resulted in signals of increased intensity. 2. High power signals failed to interfere with or blanket stations of l->wer power. 3. High power is believed no solution of the fading problem. 4. The only beneficial effect of high power is the increase of the area in which really dependable reception may be maintained. These conclusion come from the U. S. Bureau of Standards radio engineers who collaborated with the engineers of WGY in the tests on 50,000 as against 2,500 watts power, they are tentative, however, and may've modified after further high power tests are conducted. Negative Results In their report on these experiments, the U. S. scientists declare: "The results are remarkable for some things that did not happen as well as for some that did. First anti foremost, high power has not resulted in signals of overwhelming Intensity. “Kxcessive interference or blanketing of lower power stations Is anrther element of the popular picture of superpower which has failed to materialize. "The most startling conclusions are in reference to fading, or signal fluctuation. At all distances

greater than about fifty miles from a station, actual tests show that the received wave intensity is continu-’ ally fluctuating, the variation from maximum to minimum being as great as 100 to 1. Fading Persists "Increasing the power was found to effect no improvement in the degree of fluctuation. It can therefore he definitely stated that high power is not the solution of the -fading problem. "For still another reason, the distance over which a broadcast station gives highly satisfactory, dependable service is quite limited. This is the omnipresent background of static and all sorts of electrical disturbance, which requires that the radio wave have more than a certain minimum intensity in order to assure reception free from interference. "There is an area around every broadcast station within which sucji perfect reception is assured and beyond which it is not possible to rely on night-time reception free from disturbance. This zone of really dependable radio service around each broadcasting station is surprisingly small, but its area is approximately proportional to the station’s power. "This is found to be the prime reason which makes high power even desirable from the standpoint of improved public reception.” SIX IN ONE NIGHT Chicago streets were cleared by police one night to permit two artists of Station KYW, race to six different stations in the same city and put some of their hits on the air at each stop. Some of the stations were art opposite ends of the city, yet the entire stunts was completed in six hours.

Wireless Imitates Thunder Storm Bu Ah. A Ben in CTjENVER, Sept. 21.—The Ll I latest novelty In radio I 1 *' I feature programs is synthetic thunder storms broadcast by KOA. Radio thunder, say officials of the station, can penetrate four cornel's of one or more continents by use of a single broadcasting station. "The Storm,” a composition and arrangement by Clarence Reynolds, municipal organist, can be heard as the closing feature of the noonday Tuesday and Friday pipe organ recitals broadcast from the Denver public auditorium. This striking imitation of a thunder storm has won unusual applause from western radio listeners.

CONCESSION IS REQUIREMENT Poland Has Government Regulation for Stations. The operation and maintenance of broadcasting in Poland requires special concessions, according to consular advices to the Department of Commerce. The number of broadcasting stations, their power and effective area shall be determined in the concessions, the advices disclose. Persons holding broadcast concessions are permitted to charge subscription fees, the extent of which shall be determined by a tariff. Subscription tariffs will be subject to the approval of the Ministry of Industry and Commerce and will be published in the Monitor Polski, It Is reported. A one-tube reflex makes a good portable set.
