History
This station first began in 1954 as the first weather radio system in the Chicago area dedicated to the aviation user and continued until 1958 when the aviation broadcast went dark. Ivan Brunk, meteorologist in charge of the Chicago U.S. Weather Bureau (now National Weather Service) office at that time, suggested that the radio service be reinstated and put to Marine usage on an experimental basis. The marine weather broadcast was an immediate success, and the service became permanent two years later.
Throughout the 1960s, programming was expanded to include weather information for the general public, as well as the marine community. In the early 1970s, the forecast office moved from the University of Chicago to a location on West Pershing Rd. The 300 watt transmitter was located on the roof of the six-story building where it remained until 1975 when the transmitter was relocated to the Sears Tower (now Willis Tower).[5]
