The March of Radio
401
complishment for a few watts, radiated at a wavelength of a few hundred meters, to span thousands of miles of land and ocean. Of course the transmission of these waves is no better to-day than it was a few years ago; the advance has come about in the better receiving sets which have been introduced in the short wave receiving station.
We must always discount the statements of publicity and advertising managers because of their well paid enthusiasm, but we are much startled to see in an English radio journal, "Get America every night." If we discount this claim 50 per cent, and think of the English boys getting America only every other night, we can realize what tremendous progress is taking place. It's only two years ago that this was accomplished for the first time by the best amateurs and apparatus America could afford!
It won't be many years before many of us consistently hear English programs, if they will run their stations sufficiently late at night for us. Incidentally there must be lots of sleep lost by the enthusiastic British listeners, who wait until about three o'clock in the morning to hear our speeches and jazz.
And not only in the British Isles are our stations being heard, and even used for modulation of local stations, but from far off Cape Town, 8,000 miles from our eastern coast, we get reports of the reception of weaf and wgy.
How Broadcasting Reached a Balloon
THE Springfield station of the Westinghouse Electric and Manufacturing Co., wbz, is reaching out and up. During the recent James Gordon Bennett Cup races for free balloons, held in Europe, the pilot of one of the entries,
Mr. Van Orman of balloon Goodyear III, picked up its radio messages and sent to station wbz the following cablegram from Amsterdam.
"Heard call letters 2:37 Monday morning — Van Orman."
It may seem odd that a balloon perhaps two or three miles high should be able to pick up earth-conducted radio signals, but from what we know of radio transmission and its relation to airship reception it seems sure that he would have received them almost as well had he been ten or twenty times as high — which is of course impossible for a machine which depends upon the supporting power of the air to keep it aloft.
