Robert K. Karlowa had an longtime interest in radiotelegraphy, starting in 1907,[3] and by early 1913 was "the chief operator of the Tri-Cities Wireless club",[4] which met on the sixth floor of the Best Building in Rock Island, Illinois.

In mid-1915, he and Ray E. Hall, representing the Tri-City Radio Laboratory, were issued an Experimental license for station 9XR,[5][a] which also operated from the Best Building.

A second standard amateur license, 9BY, was issued in the name of the Young & McCombs co-operative store, located in the Best Building in Rock Island, Illinois,[8] where Karlowa was the head of the radio department.

Effective December 1, 1921, the U.S. government adopted a regulation requiring that stations making broadcasts intended for the public now had to hold a Limited Commercial license.

On February 18, 1922, the Karlowa Radio Corporation was issued a new license, for a broadcasting station with the randomly assigned call letters of WOC, still located in the Rock Island Best Building.

In October it was upgraded to a state-of-the-art 500 watt Western Electric transmitter,[14] which allowed WOC to move to the more exclusive "Class B" wavelength of 400 meters (750 kilohertz).

In 1924, the American Telephone & Telegraph Company was in the process of forming a radio network, with its flagship at WEAF in New York City.

The Federal Radio Commission's General Order 40 reallocated frequencies in 1928, and WOC was reassigned to share time on 1000 kilohertz with the Banker's Life station in Des Moines, Iowa, WHO.

This company purchased both WOC and WHO, which were then synchronized to simultaneously broadcast identical programs on their shared frequency, each using a 5 kilowatt transmitter.

In 1989 Mr. Miller entered the motion picture business as a producer and Ms. Palmer took over complete control of the properties, then known as Signal Hill Communications, Inc., until it was sold in 1996.
