It airs a full service radio format including news, talk, sports and farm reports.

[7] Less than two years later, December 18, 1934, the new Federal Communications Commission (FCC) authorized another increase in power, to the current 5,000 watts.

Starting in the late 1920s, orchestra leader Lawrence Welk spent a decade performing daily without pay on WNAX.

Speece was still continuing to do her Marconi Award-winning broadcast more than sixty years later when WNAX celebrated its eightieth anniversary in 2002.

[9] Other well-known regional radio personalities from WNAX have included Norm Hilson, Whitney Larson, "Happy" Jack O'Malley, Bob Hill, Ed Nelson, Jerry Oster, Carl Thoreson, Steve (Mike) Wallick, George B. German, Roland "Pete" Peterson and the hillbilly performers on the WNAX Missouri Valley Barn Dance show.

In December 1944, the Blue Network announced that WNAX, along with Cowles sister stations KRNT in Des Moines and WCOP in Boston, would be among six new affiliate, effective June 15, 1945.

The new owner was Peoples Broadcasting Corporation, a subsidiary of Nationwide Mutual Insurance Co., which, in turn, was an affiliate of the Ohio Farm Bureau Federation.

[23] Today WNAX continues many of the traditions started in 1922 with frequent news, sports, weather and farm market updates.

WNAX's 5,000-watt signal provides unusually large daytime coverage, equivalent to a full-power FM station.

It provides at least secondary coverage during the day to most of the eastern half of South Dakota, much of western Iowa, southwestern Minnesota, and most of the densely populated portion of Nebraska.

Under the right conditions, its daytime signal penetrates as far south as Kansas City, as far north as Fargo and well east of Des Moines with a good radio.

Among U.S. stations, KNAX's daytime land coverage is exceeded only by KFYR in Bismarck, North Dakota.

WNAX's signal benefits from its location near the bottom of the AM dial, as well as its transmitter power, and South Dakota's flat land (with near-perfect ground conductivity).
