New York Tribune, Sept. 2, 1921: “J.C.H. Macbeth, London Manager of the Marconi Wireless Telegraph Company, Ltd., told several hundred men, at a luncheon of the Rotary Club, of New York, yesterday, that Signor Marconi believed he had intercepted messages from Mars, during recent atmospheric experiments with wireless on board his yacht Electra, in the Mediterranean. Mr. Macbeth said that Signor Marconi had been unable to conceive of any other explanation of the fact that, during his experiments he had picked up magnetic wavelengths of 150,000 metres, whereas the maximum length of wave-production in the world today is 14,000 metres. The regularity of the signals, Mr. Macbeth declared, disposed of any assumption that the waves might have been caused by electrical disturbance. The signals were unintelligible, consisting of a code, the speaker said, and the only signal recognized was one resembling the letter V in the Marconi code.”
