WPRQ

WPRQ went on the air in the Kingsport/Johnson City/Bristol area of Tennessee in 1984.  This 1986 sticker dates back to their original Contemporary Christian format.  870 AM now has the call letters WPWT and plays Classic Country as "The Possum."  They are a daytime-only station to protect the clear-channel signal of WWL in New Orleans.
 

WMFL

1090 AM WMFL was on the air in (W) Monticello, FLorida from 1969 until some time in the 1990s.  Looking back through various Broadcasting Yearbooks, it looks like they existed like normal until around 1993.  The entries for 1994 through 1997 list them as "not on air, target date unknown" and nothing at all after that.
