Sparks Flew: WOSU's Century on the Air: Trillium Books
Autor Thomas M Rielanden Limba Engleză Paperback – 5 mar 2023
Wireless Morse code began a new age of communications, magically sending invisible waves through the ether received at some distant place. Among the first universities to experiment in this unknown world was The Ohio State University, which became one of the first educational broadcast stations and a think tank for the future of public service radio—pioneering radio audience research and serving as an innovative school of the air.
Sparks Flew is a rich story of creative, tenacious men and women working in a new medium that commercial enterprises soon dominated. At any moment in time, educational broadcasting could have failed if not for a few land-grant institutions like The Ohio State University and prominent stations like WOSU that supported the medium. Sparks Flew is the untold story, a century in the making, of one institution and one educational station that represent the roots of today’s public broadcasting system.

Chapter 1 — The First Sparks
A roaring buzz of static echoed across the cavernous laboratory with irritating frequency, accompanied by bluish sparks. Some observers later compared it to the firing of a machine gun. To Bob Marriott, the effect was thrilling.
The young Marriott would sequester himself for long periods in an electrical engineering lab at The Ohio State University, working out the flaws in his patchwork spark gap transmitter. It was built to noisily send Morse code through the air to an equally crude receiver. Marriott was all of twenty years of age, but he was enamored with the idea of improving upon the recent invention of a young Italian whose magical machine would change the world.
Just a few years earlier, a shotgun blast across a quiet Italian valley had signaled a communications revolution. Guglielmo Marconi had been experimenting for years with sending electromagnetic waves through the air as a way to communicate. His discoveries were built on the work of Scottish physicist James Maxwell, who in the 1860s had predicted the existence of unseen electromagnetic waves, and on that of German scientist Heinrich Hertz, who later engineered instruments to transmit and receive radio pulses. It was Hertz who invented the spark gap transmitter, but he would never realize the importance of his experiments to practical communications.
Marconi brought together the research of these and other scientists to formulate the ultimate experiment, based on thousands of tests using a combination of different coherers, receivers, sealed glass tubes, and metal fillings. It played out near Bologna, Italy, in the summer of 1895. As Marconi sat on the window ledge of his lab in the attic of his parents’ country villa, his older brother, Alfonso, and two workers walked from the villa across a valley carrying a wireless receiver device and an antenna. His brother also carried a shotgun. Marconi had already proven it was possible to send coded signals using an old railroad telegraph key and transmitter to a receiver 100 meters away, the distance to the end of the villa’s gardens. Experts at the time believed waves could be sent only in a straight line without obstructions, thinking that the main obstacle to sending wireless signals to a distant object was the curvature of the earth’s surface. After his assistants walked over a hill to a distance of some 2.4 kilometers, or 1.5 miles, Marconi prepared his transmitter and pressed his telegraph key. The key interrupted the spark and sent three short blasts for the letter “S” across the valley. An instant later, Alfonso’s shotgun blast signaled success.
It would take time for Marconi to prove to the world that true long-distance wireless communication, even across the Atlantic Ocean, was possible. But that day would shatter much of what was assumed about the use of radio waves for communications. Wireless was born.
