In 1926, there had been a temporary suspension of government regulation of radio due to a court ruling that the Commerce Department had overstepped its legal authority. This eventually resulted in the formation of the Federal Radio Commission (FRC), which as part of its re-establishment of control moved WLW to 700 kHz in June 1927, the frequency on which it has operated ever since. In November 1928, under the provisions of the FRC's General Order 40, 700 kHz was one of 40 frequencies designated as "clear channels", and WLW was assigned exclusive use of this frequency within the United States and Canada.
