Its transmitter is located off Swanson Street in Pittsburgh's North Side, on a tower shared with KDKA-TV and other FM stations.

WAMO-AM-FM served the Pittsburgh African-American community with R&B and soul music, as well as Black talk and news programming on weekdays, and religious shows on Sundays.

In the later 1960s, the FM station began separate programming, specializing in Urban contemporary music, with WAMO-AM-FM sometimes simulcasting on weekends.

It had programming on its HD2 digital subchannel beginning in 2006, launching a format focusing on Adult Album Alternative (Triple A) music.

The move made the Penguins the second North American professional sports team with their own terrestrial radio channel (after the NFL's Dallas Cowboys and their HD2 relationship with KRLD-FM).
