[1] As AM 810 is a clear channel frequency reserved for Class A stations WGY in Schenectady and KGO in San Francisco; to avoid interference, WEDO must sign off at night when radio waves travel farther.

Tri-City Broadcasting first put the station on the air and operated it until 1972, when it was purchased by 810, Inc., a wholly owned company headed by local entrepreneurs Ralph and Judith Baron.

During the 1960s and 1970s, WEDO became known for its Top 40 music presentation and even received more notoriety when they relocated their studios and offices inside Midtown Plaza Mall on Fifth Avenue in downtown McKeesport during the 1970s.

A heating problem one day in 2000 resulted in a frozen pipe bursting in the mall and leaving the radio station in about two inches of standing water.

WEDO cleared its equipment and furniture out of the mall weeks later and moved to a former bank location in White Oak at 1985 Lincoln Way, where it occupied the second floor.

In the spring of 1999, WEDO was the victim of a not-so-innocent and dangerous prank committed by local high school students at its transmitter facility in Forest Hills, as explained in the April 13, and 29, 1999 issue archives of the Tribune-Review... Police blame vandals for toppled radio tower...officials say cables cut; WEDO-AM is off air Vandals cut the wires supporting a McKeesport radio station's transmitting tower, police said, allowing high winds to blow down the tower and knock the station off the air early Monday morning.

WEDO had signed off on Sunday before 8 p.m. North Versailles acting police Chief James Comunale said two of six wires supporting the tower were clearly cut.

Station vice president and general manager John James said Wednesday a new tower has been constructed at the same North Versailles Township site as its previous one.

North Versailles police said strong winds toppled the tower after guy wires holding it in place were cut on April 11.On Tuesday, September 15, 2015, it was announced that 810 Inc. agreed to sell WEDO to Broadcast Communications, Inc. of Irwin, Pennsylvania, licensee of WKFB, WKHB, WANB, WKVE and three FM translators in the Pittsburgh market, plus other broadcast properties in the Cumberland, Maryland market.
