KTCR

97.1 KTCR operated on one of the oldest FM frequencies in Minneapolis, Minnesota which was established in 1947.  At one point they played Country music during the day and had a Talk format at night (which would help explain the provocative "Go To Bed With A Friend" slogan.)  What is it with Minnesota radio stations and their double entendres?!  Apparently on the weekends they also had a show called "Smut Talk" hosted by someone named Marv Gatch.  Some KTCR audio and photos can be found at this excellent Twin Cities Radio Airchecks site.
97.1 FM is currently "Cities 97" KTCZ, an early pioneer of the Adult Album Alternative format.
