  • Amateur Radio in the 1950S: Romance and Reality
    Amateur Radio in the 1950s: Romance and Reality by Ronald R. Thomas 6415 Chastain Dr. NE Atlanta, GA 30342 In the 1950s, amateur radio or "ham radio" seemed almost magical. There was no Internet, long distance telephone calls were expensive, and international air travel was limited. People knew that Hams talked to each other all over the world, which was perceived as glamorous and exciting. They also knew that Hams often provided emergency communications during disasters and had played an important role in military communications during World War II. Most people were pleased to have a ham radio operator in their neighborhood. They were often even quite willing to allow a ham to run a long wire antenna across their backyard. During that era, many home radios covered shortwave bands, which enabled people to listen to hams talking to each other. Some listeners decided to become hams themselves so that they could participate in this exciting hobby. Their first step would be to begin studying for a license. Licensing In the 1950s, the Federal Communications Commission (FCC) ruled supreme over the airwaves. The agency totally controlled radio broadcasting, commercial radio communications and, of course, amateur radio. Obtaining a ham radio license required passing Morse code receiving and sending tests and a stringent written exam. Every aspiring radio amateur quickly acquired a copy of the American Relay League (ARRL) publications related to licensing. These included How to Become a Radio Amateur, The Radio Amateur's License Manual, and Learning the Radiotelegraph Code. The prospective applicant worked with these self-study aids and practiced Morse code until he or she felt ready to take the exam at an FCC office.
