What is "know-fm"

KNOW-FM (91.1 FM) is the flagship radio station of Minnesota Public Radio's "news and information" network, primarily broadcasting a talk radio format to the Minneapolis-St. Paul market. The frequency was previously under the call sign KSJN, but the purchase of a commercial station at 99.5 MHz in 1991 allowed MPR to broadcast distinct talk radio and classical music services.

KNOW-FM's studios are located in the MPR Broadcast Center on Cedar Street in downtown St. Paul, while its transmitter is located on the KMSP Tower in Shoreview.
