Owned by Baraboo Broadcasting, it was formerly a sister to radio station WRPQ (740 AM and translator 99.7 FM) until the latter's sale to Civic Media.
The two outlets continue to share studios on 8th Avenue in downtown Baraboo.
W43BR's transmitter is situated on the Baraboo Range near Devil's Lake State Park, co-located with WOLX, W271DQ, W259BC, W290AL, NOAA Weather Radio station KHA-47 and several other telecommunication services.
The station aired local programming and filled its broadcast day with content from the American Independent Network and America One.
W43BR has limited Spectrum cable coverage in the Baraboo/Wisconsin Dells area, along with surrounding portions of Columbia, Sauk, Adams and Juneau counties, and western portions of Dane County on channel 10.
