General Order 40
Encyclopedia
General Order 40 was an order issued on August 30, 1928 by the new Federal Radio Commission
Federal Radio Commission
The Federal Radio Commission was a government body that regulated radio use in the United States from its creation in 1926 until its replacement by the Federal Communications Commission in 1934...

 under the Radio Act of 1927 which provided for a reallocation of the commercial broadcast radio spectrum.

As a result of implementaion of General Order 40, most U.S. radio stations were forced to change their broadcast frequencies. The frequency changes went into effect at 3:00 a.m. Eastern time on November 11, 1928.

The goals of the FRC in reallocating the frequencies were to reduce interference and "clutter" on the air, to provide better access to the airwaves to smaller cities, and "underserved" areas, and to rid
the air of "temporary" and "portable" stations. This was achieved by designating each frequency as
either a frequency for one (or more) clear-channel stations broadcasting with maximum power, a frequency to be shared by regional stations with less power, or a frequency to be shared by many local stations with limited power. Each clear channel frequency was reserved for one principal station in one of five U.S. zones or in Canada. Some of these clear frequencies were shared with one or more lower power stations in locations remote from the principal station. The U.S. was divided into the five zones used by the Radio Act of 1927, as shown on the map to the right.

The allocation scheme introduced by General Order 40 stayed in place for over twelve years, until the implementation of the North American Radio Broadcasting Agreement
North American Radio Broadcasting Agreement
The North American Radio Broadcasting Agreement, usually referred to as NARBA, is a treaty that took effect in March 1941 and set out the bandplan and interference rules for mediumwave AM broadcasting in North America. Although mostly replaced by other agreements in the 1980s, the basic bandplan...

 in March 1941.

The table below presents a general outline of the frequency allocations under the order. For "Clear" frequencies, the zone allocated to the principal station on that frequency is given, along with the principal station that actually occupied the frequency, the previous frequency of the actual principal station, and other stations that shared the frequency. Station call signs shown in parentheses are stations owned by the same licensee of the principal station on that frequency.
