Station WIP, .the powerful broadcaster on, the Glnhbel Brothers st6re, in this cfty, has completed arrangements with 2LO, the London station of the British i Broadcasting. Company, to bi'oahqast to each other during the hours next Saturday, when the moon will come between the sun and the earth, causing a complete eclipse. Scientists all over this country and Europe have erected delicate apparatus to study just what effects this eclipse will have on radio waves, but it remains fcjr tyiP and 2LO to arrange the test ; that will be of greatest interest fans. Station WIP W4IL broadcast musicby jack Le Royj ; and his orchestra from 7 tc> 9:30 a. m., eastern standard time; .21,0 at .London will begin its program l promptly at 9:30 and continue to lid. m. The’ theory so, fur has been that the sun’s rays hinder the progress of the wavfe emitted from broadcasting stations, so ipreventing longdistance work. The path of the eclipse extends from Philadelphia, where totality Will |be 98 per cent,, directly over the path to London. Radio engineers at both stations feel that the eclipse will have enough effect on the radio waves to allow at least a part of the program to reach the other: continent. Ships at sea, bet Ween the two stations, will be askeid to listen in for the broadcasts, and in event of hearing either WIP or 2LO, radio a message to the station! heard, giving their exact nautical, iposition and the time at which the signals were audible. This will give valuable information with which jto Compute the effect of the eclipse on radio transmission. . Not for ninety-nine years will there be another opportunity for such a transatlantic test, as there will not
