I am not aware of anyone airing beautiful music or easy listening into the 1980s. I think this is what the FM dial looked like in 1980.
90.7 -- Run from Central HS, unclear programming
91.5 -- Eclectic, featuring some jazz hours
92.5 (Owb) -- Country
96.1 (Owb) -- AC
98.1 (Princeton) -- Country
99.5 (Henderson) -- Prog Rock
103.3 -- Top 40
104.1 -- MOR
105.3 -- Religion
Several other stations that serve the area now did not yet exist, such as 88.3, 93.5, 94.9, 95.3, 106.1, 107.1 and 107.5.
