, GE effected a breakdown of 790 kHz. WGY would assume the maximum permissible power, and KGO would be lowered in power to 7,500 watts. That was then lower than the minimum permissible power for a clear channel station (10 kW), and also was then higher than the then maximum permissible power for a regional channel station (5 kW). Both stations retained omnidirectional antennas. Therefore, GE effectively removed from the West one of its eight clear channels and added another clear channel to the East, thereby giving the East nine cleared channels and the West only seven. The other "regions" in the Band Plan all retained their allotted eight cleared channels.

1940s and 1950s

In 1941, stations on 790, including WGY and KGO, were moved to 810 to comply with the North American Regional Broadcasting Agreement (NARBA). On December 1, 1947, KGO switched to a directional antenna and its power was increased to 50,000 watts, the new minimum standard power for a U.S.

Solar power

In March 2008, solar panels were installed at KGO's transmitter site in Fremont, California, to offset some of its power consumption during daytime hours. The effort is a testbed for Pacific Gas and Electric Company and is located near the Dumbarton Bridge. The solar system uses both CPV (SolFocus) and PV (Premier Power) arrays and provides about 17 Kilowatts, or 33% (one third), of the radio frequency (RF) power output from the 50KW transmitter (or about 1/10th of the total power consumption of their transmitter site over a 24-hour period). United States Speaker of the House Rep. Nancy Pelosi turned the system on during an on-air ceremony.
