WSDP began as a dream of Plymouth High School English teacher Bonny Dore and principal Bill Brown in 1969, as preparations began to replace Plymouth with Salem High School. The station broadcast at 89.3 FM from its 1972 sign-on until October 1977, when a frequency swap with Eastern Michigan University’s WEMU, which had been at 88.1, saw WSDP taking over 88.1 and WEMU moving to the 89.1 spot on the dial, where it remains to this day. The station commenced Stereo broadcasts in 1985.
