WGKB (1510 kHz) is a commercial AM radio station licensed to Waukesha, Wisconsin, and serving the Greater Milwaukee media market.

It is owned by Good Karma Brands, broadcasting a talk radio format aimed at Milwaukee's African American community.

AM 1510 is a clear channel frequency reserved for WLAC in Nashville, so WGKB must go off the air at night to avoid interference.

That arrangement ended after Good Karma Broadcasting moved the WAUK sports format to its new, full-time frequency of 540 kHz, the former home of Christian radio outlet WRRD, owned by Salem Media.

The application was made on August 19, 2020, shortly after putting the dormant Waukesha studio facility and transmitter site up for sale.

The station's social media referred listeners to WTTN and its streaming presences with the shuttering of Crute's main studio facility on Brady Street in Milwaukee.

This came as former owner Michael Crute negotiated with Good Karma to trade the stations, while strengthening its Madison presence.

[8][9] On September 29, 2020, Good Karma announced that WRRD would become a talk radio station focused on the city's African American community, branded as "101.7 The Truth".

[11] The new format launched on January 4, 2021, utilizing a live 7 a.m.–6 p.m. schedule of four programs that repeat at night, albeit exclusively over W269DL after WGKB's dusk sign-off.
