Part of our The Evolution of Amateur Radio timeline series.
By the early 1930s, amateur radio had already changed regulatory hands once, from the Department of Commerce to the newly formed Federal Radio Commission under the Radio Act of 1927. That arrangement didn’t last long either. In 1934, Congress passed the Communications Act, creating the Federal Communications Commission and handing it authority over every amateur license in the country, an arrangement that’s still in place today.
Why the reshuffle happened
The Federal Radio Commission had been created in 1927 mainly to sort out chaos in the broadcast band, where far more stations wanted airtime than there was spectrum to give them. That chaos traced back to an earlier failed attempt at order: the Washington international radio conferences of the 1920s tried to coordinate spectrum use globally, but domestic broadcast interference in the US had gotten so bad by the mid-1920s that Commerce Secretary Herbert Hoover, who had overseen amateur licensing since 1912, could no longer manage it under his existing authority. By the early 1930s, Congress wanted a single agency overseeing all forms of electronic communication, radio, telephone, and telegraph, instead of splitting authority across multiple bodies. The Communications Act of 1934 consolidated that authority under the FCC.
What actually moved from the FRC to the FCC
The Federal Radio Commission had only ever regulated radio. The Communications Act of 1934 dissolved it and folded its functions into a much broader Federal Communications Commission that also took over interstate telephone and telegraph regulation, previously split across the Interstate Commerce Commission and other bodies. For amateur radio specifically, day-to-day administration didn’t change all that much in the short term: the same examiners, the same basic licensing process, the same field offices. What changed was the chain of command above them, and the fact that amateur radio now sat inside an agency with a much wider mandate and, eventually, far more resources than the FRC had ever had.
Amateur licenses reorganized into Class A, B, and C
Under the new FCC, amateur licensing was restructured into three classes. Class A conveyed all amateur privileges, including reserved radiotelephone bands, and grandfathered in existing Amateur Extra First Grade licensees and First Class licensees with unlimited endorsements. Class B held full privileges except the reserved radiotelephone bands, and Class C offered the same privileges as Class B but let applicants test with other amateurs rather than traveling to an FCC field office, similar in spirit to the old Second Grade license from 1912.
Growth through the Depression
Despite the economic hardship of the era, the hobby kept growing. By 1936, there were an estimated 46,000 licensed amateurs in the US, more than three times the 1923 census figure, as radio technology became cheaper and more accessible even during the Depression. Herbert Hoover, who by then had gone on to become president and later returned to public life as a strong advocate for the hobby he’d helped regulate as Commerce Secretary, remained a visible supporter of amateur radio until his death in 1964.
New bands and new technology on the horizon
This period also saw the first serious amateur experimentation with single sideband, with Robert Moore, W6DEI, beginning SSB voice work on 75 meters in 1933. By 1934, several stations were operating SSB, years before it became the dominant voice mode it is today. SSB offered a real advantage over the standard AM phone of the era: it packed the same voice signal into roughly half the bandwidth and concentrated all the transmitter’s power into the part of the signal that actually carried information, but the equipment needed to generate and receive it was complex enough that widespread adoption wouldn’t happen for another two decades. The FCC era had barely started and amateurs were already pushing into new technical territory.
What came next
The FCC structure held through the rest of the decade, but world events were about to interrupt amateur radio again.
