Radio Act of 1912

The Radio Act of 1912 was a federal law that required all seafaring vessels to maintain 24-hour radio watch and keep in contact with nearby ships and coastal radio stations. Part of the impetus for the Act's passage was the sinking of the RMS Titanic. Other factors included an ongoing conflict between amateur radio operators and the U.S. Navy and private corporations, that included the amateurs forging naval messages and issuing fake distress calls.

The Wireless Ship Act of 1910 was seen as too weak to address the problems. The U.S. Congress considered six different proposals for replacing it in the period between 1910 and 1912, eventually enacting the 1912 Act.

The Act set a precedent for international and federal legislation of wireless communications. It was followed by the Radio Act of 1927.

The Act required all amateur radio operators to be licensed and prohibited them from transmitting over the main commercial and military wavelengths. The task of implementing the Act was the responsibility of the Secretary of Commerce and Labor. The Department of Commerce and Labor was empowered to impose fines and to revoke the licences of those amateur radio operators who violated the Act.
