WKHB

WKHB is an AM radio station licensed to Irwin, Pennsylvania, United States, which serves the greater Pittsburgh area. Known as 620 KHB, the station operates with 5,500 watts daytime (reduced power at night) and airs a mix of health talk and paid programming with oldies music in the morning, evening and overnight hours. It is also known for its weekend polka shows.

WKHB's high power on a low frequency yields what is generally considered to be the second-best daytime AM signal in the Pittsburgh area (behind KDKA), covering nearly two million people in various portions of five states. Veteran Pittsburgh radio personality and programmer Clarke Ingram was named Program Director in 2005 and promoted to Operations Manager in 2006. Michael J. Daniels was hired as Assistant Program Director in 2007 and appropriated the Operations Manager position from Ingram in 2010; Ingram relinquished his remaining duties in 2011. Station owner Bob Stevens now holds the dual titles of General Manager and Program Director.

WKHB and its sister station WKFB (770) are owned by Broadcast Communications Inc., which also owns and operates radio stations in Waynesburg, Pennsylvania.

WKHB simulcasts on translator W231BM 94.1 from Clairton, Pennsylvania.
