WTWS, known as 92.1 The Twister, is a 920-watt radio station broadcasting at 92.1 FM in Houghton Lake, Michigan, with a country music format.

Formerly licensed to Harrison, Michigan and operated as a satellite of public radio station WVXU Cincinnati for several years and owned by Xavier University (then transferred to Cincinnati Classical Public Radio along with WVXU), the station was formerly owned by Sindy Fuller's Bridge to Bridge, Inc., owner of WUPS 98.5 Houghton Lake, Michigan, and adopted the "Twister" format in June 2006.

As radio stations started tossing out vinyl in the 1980s for CDs, WKKM didn't fully make the conversion.

In 1981, Carmine started what would later become an AM simulcast for WKKM, known as WDEE AM 1500, the call letters were taken from a legendary Detroit country station (The Big 'D'), and later given up.

It continued as a simulcast outlet of its FM sister until 2001 when it began a short lived automated classic country format.

WKKM had a full-service feel to it, as the station had religious programming all day Sunday, plus funeral announcements and Paul Harvey News and Comment.

However, the station didn't make a profit and Foster sent the license back to the Federal Communications Commission (FCC), silencing WWKM 1540 forever in 2004.

After sister station WUPS, which primarily targets the Mount Pleasant area, was granted a construction permit to change its city of license to Harrison (with no change in facilities), WTWS received a construction permit to move to Houghton Lake in order that there would still be a radio station licensed to Houghton Lake.

From the new facilities, 92.1 FM's signal in the southern part of its former 6,000-watt coverage area, such as Mount Pleasant and Clare, is significantly less strong, but the station can now be heard more clearly in former fringe coverage areas such as Houghton Lake, Higgins Lake, West Branch, St. Helen, and Roscommon, and northward to Grayling.

In 2008, a new 100-watt FM facility at 90.7 licensed to Harrison was granted the WKKM call letters after they were dropped by an Alpena-area contemporary Christian station that had been using them.

WKKM was sold to West Central Michigan Media Ministries and became WBHL in September 2012, simulcasting the religious programming of WGCP in Cadillac.

Under Media Ministries' ownership, 90.7 FM's power has been boosted to 10,000 watts and the station now easily covers all of central Michigan.
