provided an advertising gimmick for Julius Brunton & Sons, operators of an automobile service station and local distributor of
Willard Storage Batteries, which were popularly used in both experimental transmitters and receivers during radio's early days. Shortly after making its debut, KFUQ became KJBS.
The station's first address was 1380 Bush Street, a building which remains an auto-service facility today. In its early years, the station broadcast police dispatch calls, among its regular schedule, in the days before police departments could afford their own radio transmitters.
In 1927, KJBS's power was increased to 50 watts and, on March 1, 1928, to 100 watts.
On April 5, 1929, the station's frequency was changed to 1070 kHz.
On April 19, 1930, KJBS debuted its ''Owl'' program, signing on at midnight.
In the mid-1930s, its power was increased to 500 watts.
In the 1940s, in order to increase its range of coverage, KJBS was assigned to 1100 kHz, sharing time with the dominant station in North America on 1100 kHz, which was in Cleveland. This required that KJBS go off the air at local sunset, but allowed it to come back on the air when Cleveland signed off at 1:00 a.m. in the East, 10:00 p.m. local time. By this time, KJBS had moved to 1470 Pine Street, a building incorporating a stand-alone vertical transmitting tower at the front entrance to the building.
In 1959, KJBS was granted a construction permit to increase its daytime power to 50,000 watts. This change in broadcasting power required the station to operate one of the most distinctive schedules in the history of broadcasting. It operated from a directional set of four towers in the suburban town of Hayward from 6:00 a.m until local sunset, then from the Pine Street 1,000 watt transmitter from 10:00 p.m. until 3:00 a.m. (when Cleveland's
