WDLS

The station was founded in 1969 by Obed S. Borgen and originally went on the air as WWDA on 990 kHz (the call sign stood for "Wonderful Wisconsin Dells Area").

WNNO-AM-FM split its simulcast and programmed Country Hits in 1982, and broadcast Chicago Cubs baseball from 1983-1985.

During the early-mid 90s its format alternated between sports and a simulcast of sister Top-40 station WNNO-FM (106.9), or was otherwise off the air, usually after sunset.

WNNO and WNNO-FM had studios together on Superior Street in Wisconsin Dells and would usually be on the air from 6 a.m. to midnight.

In the late 1990s WNNO-AM-FM were purchased by Magnum Radio Group; the studios were moved to Church Street, Wisconsin Dells.

In March 2005, the online audio stream of WDLS-AM, as powered by Warp Radio, went live on its website to further increase its potential audience across the Internet.
