They called it “wireless” in those days. Only a few enthusiasts throughout the country bought the kits, assembled them, then listened eagerly for messages from other enthusiasts. They could originate from anywhere. That was part of the fascination of it: trying to determine exactly where a message was being broadcast from, and how far it had traveled.
In Lloyd Douglas’s scrapbook, there are two newspaper clippings about an upcoming wireless experiment on New Years Eve, 1919. Neither one tells us the name of the newspaper, but one, entitled “Will Wireless Greetings on New Years Eve” (see above), is either from the University of Michigan or from an Ann Arbor paper; the other (see below) is apparently from the Detroit Free Press and is entitled, “U of M to Radio 1920 Greetings.”
According to the first of these: “On the evening of December 31, [1919,] just before the new year is ushered in, radio operators at the university radio station will send out greetings for the year to all parts of the country. Community Service, Inc., under whose direction the movement is being carried on in all sections of the United States, from the Atlantic to the Pacific, is starting what will probably be an annual event in a great publicity campaign.”
Wireless radio was such a new thing that they had to perform stunts like this to make people aware of its potential. The article continues:
“Every radio station in the United States will send out New Years greetings during the evening, and all amateur operators are urged to ‘sit in’ and copy each message received.”
A paragraph later, the article says that the university “will use both the radio telephone and the radio telegraph.” That’s how new this technology was: what we now call “radio,” they called “the radio telephone” to distinguish it from “the radio telegraph,” which was, apparently, a wireless transmission in Morse code.
From the Detroit Free Press: “The telegraphic message will be sent out at 8:30 the evening of December 31, and the wireless telephone will follow 15 minutes later. The message, which is not to be made public before it is sent, was written by Rev. Lloyd Douglas, Congregational pastor of this city [Ann Arbor], and is 60 words in length.” [They were referring to the “telegraphic” message. His “radio telephone” message would be longer.]
The event would be under the direction of Lieutenant-Colonel John Lucas, head of the signal corps work at the university ROTC, and Professor J. C. Evans of the university faculty. There was an official aura around this technology, with the ROTC providing a kind of military authority to it. Things would be very different later, when radio would become a commercial enterprise.
As both articles said, “A rotary spark transmitter will be used by the university station, and for receiving the telegraph message, receiving tuning sets should be set at 600 meters wavelength. For receiving the radio telephone message, tuning coils should be set at 660 meter wavelength.” The organizers hoped that amateur operators all over the country would write down whatever messages they received, then mail them back to the university with detailed information about their location.
It was an exciting experiment, and it was just the kind of thing that Lloyd Douglas would be involved in, not just because of his interest in science but also because of his eagerness to pursue new ways of expanding his audience. I’ll tell you about his messages in my next post.
