flagship radio station ofMinnesota Public Radio 's "news and information" network, primarily broadcasting atalk radio format to theMinneapolis-St. Paul market. The frequency had previously gone under thecall 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.WLOL 1330 AM was purchased by MPR in 1980 and carried the KSJN call sign until 1989 when the KNOW letters became available. The AM signal was later spun off into a for-profit subsidiary to help fund the public broadcaster, and was eventually sold off. As of 2005 it goes under the original WLOL name.
In the 1970s, KSJN 91.1 FM and WLOL 99.5 cooperated in an experimental use of
quadraphonic stereo, with each station carrying two channels of audio. However, this "quadcast" had some undesirable "ping-pong" effects, much like early stereo broadcasts using the same method did. Somewhat ironically, KNOW currently broadcasts primarily inmonaural as its schedule is not music-focused.Austin, Texas
The callsign KNOW was also used by a major
adult contemporary radio station inAustin, Texas , located at 1490 kHz. The station signed off in 1989 after operating for 50 years. The Spanish stationKFON assumed the frequency in 1993.ee also
