Whether these transmissions featured locally gathered returns from Wisconsin or were telegraphic relays of material received from KDKA is not known. As 1920 drew to a close, a new telephonic transmitter designed by Terry and built with the help of Hanson and other students was ﬁnished and had undergone testing. 36 This would make November 7, 1920, the ﬁrst day of regular noncode broadcasts on 9XM.
It would incorporate improvements he had achieved in the design of transmitter tubes. 34 Telephonic Broadcasting by 9XM Prewar “wireless squad” member Malcolm Hanson had returned to the university after his stint in the navy and enrolled as a student to continue his work toward his undergraduate degree. He arrived in late June 1920 and Terry asked him to help construct a permanent station for telephonic broadcasting. Terry had always recognized Hanson’s passion for wireless and realized that, with his three years of experience as a navy radio operator, he would now be even more useful to the Wisconsin operation.
Part of the fun for amateur wireless enthusiasts was listening in to the Morse code messages sent from point to point. This led some to believe that the true value of wireless telegraphy was to use this eavesdropping phenomenon to eﬃciently send a single message to many people at once. The student operators at 9XM occasionally experimented with this concept when they were testing the equipment. As part of some point-to-point transmissions, they would ask anyone who heard the message to respond.
