They were Albert S. Hyman, Bob Almy and Poogie Murray. At first they called their station Hyman-Almy-Murray. Tapping out such a long name in code soon became tiresome and called for a revision.

The resulting interference came to the attention of congressional committees in Washington and Congress gave much time to proposed legislation designed to critically limit amateur radioactivity. In 1911, Albert Hyman chose the controversial Wireless Regulation Bill as the topic for his thesis at Harvard. His instructor insisted that a copy be sent to Senator David I. Walsh, a member of one of the committees hearing the bill. The senator was so impressed with the thesis that he asked Hyman to appear before the committee. Albert Hyman took the stand and described how the little station was built and almost cried when he told the crowded committee room that if the bill went through they would have to close down the station because they could not afford the license fees and all the other requirements, which the bill imposed on amateur stations.
