The radio studios and offices for WDSM, KDAL, KDAL-FM, KDKE, WDUL and KTCO are at 11 East Superior Street, Suite 380, in downtown Duluth.
Because 710 AM is a clear channel frequency reserved for WOR New York City and KIRO Seattle, WDSM reduces power to 5,000 watts and uses a directional antenna with a four-tower array at night to avoid interference.
[2] WDSM airs a sports format branded as The Game with daytime programming originating from WRNW in Milwaukee.
WEBC became the Mutual affiliate and WDSM began carrying NBC Radio programming and news.
This was a direct result of WDSM's commitment to television and its founding of WDSM-TV on March 1, 1954, as an NBC affiliate (now KDLH-TV).
