Thanks to the boys of our northern-most district office


Those were the lawless days of radio


William Dubillier,22 years old at the time, came to Seattle to install a radio station for the Commercial Wireless Telephone Manufacturing Company.


The apparatus was of the "singing arc" type and operated on a wavelength of 4,000 meters. For an antenna, Dubilier used a huge umbrella shaped affair containing about 40,000 feet of wire, suspended from a wooden tower 320 ft. high. The bottom of the umbrella embraced a circle on the ground almost a quarter of a mile in diameter ...


... J. H. MacDonald, being first duly sworn, upon oath deposes and says:


That he is one of the wireless telegraph operators in the employ of the Canadian government at Point Grey station, which is equipped with an aerial about 225 ft, in height, of the umbrella type, consisting of eight wires with silicon detector and standard receiving set of the Shoemaker type: that his shift, as operator, is from 3:30 P.M. until midnight, and that on or about the first day of May, 1911, while tuning for signals between 10 and 11 o'clock, he picked up a wireless telephone message from William Dubilier's telephone station located in Seattle, Wash., and was able to hear his voice clearly and could catch the words distinctly, ' Hello, hello, hello ', then nearby telegraph stations interfered, so that the signal became intermittent, but at the end, he again heard the voice distinctly, ' Good night '. Affiant further states that on other occasions, while on duty at such station, he picked up portions of musical selections and conversations, all of which could be distinctly heard."


The date of the affidavit is July 20, 1911.
