WZRK (1550 AM) was a radio station licensed to Lake Geneva, Wisconsin, United States. Its studio and transmitter were located on State Highway 50 east of Lake Geneva.^[2] The station ran 1,000 watts during daytime hours, with a two tower array and a directional pattern to the east and west.^[2]^[3] Prior to being taken off the air, nighttime operations were added, running 1 watt.^[4]

History

The station began broadcasting on May 15, 1964, and held the call sign WMIR.^[1] The station's call sign was based on the name of its president and co-owner Miriam Monroe.^[5]^[1]^[6]

The station went in a couple of formats for the first three decades. First middle-of-the-road in the 1970s, and then adult contemporary from 1983 until August 28, 1991. On that day, the station switched to News/Talk. Four years later in 1995, WMIR was sold to Walt-West Wisconsin for $120,000.^[7] The station dropped its news/talk format and adopted a sports format in January 1996 (as it first announced in October 1995), and its call letters were changed to WAUX as a simulcast of Waukesha's AM 1510 WAUK.^[8]^[9]

In 2001, the station was sold to Starboard Broadcasting.^[10] On November 12, 2001, the station's call sign was changed to WZRK.^[9] The station was silent in 2001 and 2002.^[11]^[12] The station was one of the original affiliates of the Catholic talk network, Relevant Radio, when it was launched in 2003.^[13] In 2008, the station's license was transferred to Sovereign City Radio Services.^[14] The station was silent for a period in 2008 and 2009.^[15]

In October 2009, the station began airing the Timeless Cool format, featuring a mix of jazz, blues and adult contemporary music, and was branded "Avenue 1550".^[4]

In 2009, Sovereign City Radio and Nelson Multimedia formed GS Radio of IL, and ownership of WZRK was transferred to this company.^[4]^[16] In November 2010, WZRK was granted a Federal Communications Commission construction permit to change its city of license to Northbrook, Illinois with a power of 1,500 watts nondirectional daytime only.^[4]^[17] Nelson Multimedia's WCSJ in Morris, Illinois would have surrendered its license in order for WZRK to move to Northbrook.^[4] However, this construction permit expired and no action was ever taken.^[17]

The station was silent throughout much of 2012, 2013, and 2014.^[18]^[19]^[20]^[21]^[22] In October 2014, WGLB, LLC., owner of WGLB in Elm Grove, Wisconsin, purchased WZRK for $100,000.^[23]^[24] In January 2015, WGLB, LLC requested the FCC cancel WZRK's license.^[9]^[25] This allowed for 1560 WGLB to increase its daytime power.^[26]
