Radio 84 WHAS (Depend On It)

WHAS, known by the on air branding as "84 WHAS", is an AM radio station broadcasting in Louisville, Kentucky. It is a 50,000 Watt clear channel radio station assigned to frequency 840 kHz. With clear channel status, its nighttime signal can be heard in most of the continental U.S. and much of Canada, and even in other countries at time.

Its first broadcast was on July 18, 1922. It was originally assigned the frequency of 350 kHz.

On May 16, 1925, the first live broadcast of the Kentucky Derby was originated by WHAS and was also carried by WGN in Chicago. The call of the Derby featured an announcer who watched from the windows of one of the famous twin spires of Churchill Downs.

During the 1937 Flood the station aired 115,000 messages. On March 29, 1941 the station moved to its current frequency of 840 AM. On March 30, 1970 WHAS began 24-hour operation.

The station was originally part of the local media empire ruled by the Bingham family, which also published Louisville Courier-Journal (now owned by Gannett) and operated television station WHAS-TV (now owned by Belo), originally a CBS affiliate, now with ABC. WHAS Radio is currently owned by Clear Channel Communications

The station has been broadcasting on a full time basis in the IBOC digital radio mode, using the HD Radio system from iBiquity, since September 2007 after an initial testing period which started in 2006. Prior to 1995, WHAS broadcast in C-QUAM AM stereo.
