The enclosed information is @ condensed summary of a letter received from the General Electric Company, Schencctady, relative to radio propagation tests 20,000 to 40,000 K.C. (15 to 74 metres). The General. Electric Company are anxious to accumulate as much data as possible on these: tests, and would appreciate very much: reports from amateurs in New Zealand. re Hach test will.run continuously far 80 hours, and. they. state that it m: id prove difficult to pick up some of théka transmissions .on- account of propagation phenomena and uncalibrated receiving sets. To facilitate this matter they haye given a forecast of the time at which they believe reception: will most likely be effected (in New Zealand) :- 6.30 a.m.-12.30 p.m. (N.Z.T.). 7.30 p.m.-10.30 p.m. (N.Z.T.).: Propagation Test-20,000 to 40,000 K.C, For the purpose of gathering additional radio propagation data at high frequencies, the General Plectric Company at Schenectady, New York, will conduct ‘a 20,000 to 40,000 K.C. propagation test during the months of July and August, 1929. ‘ . Listeners in various parts: of the world are being advised of this test; and it is hoped that from the quantity,§ of reception data that will be forthcoming considerable new information may be obtained relative to 20,00040,000 K.C. performance. : The transmitter utilised at Schenectady will have its frequency crystal controlled and a normal power output of approximately 2 K.W. The antenna will be a simple non-directive structure. The call letters utilised will be. W2XAW. The material transmitted will consist entirely of ©.W. (continuous wave) transmission. At few minute intervals the station call, the frequency on which the station is operating, and the frequency which will be used during the subsequent trang-’ mission will be given, The initial transmission will be ‘on a frequency of 20,000 K.C. and will begin at 16.00 G.M.T., July 2.
