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 had previously gone 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.

Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning.
