This is what we have so far about what made WDTH FM tick. Bits and pieces of this brief narrative came from a variety of sources. Someday very soon, the contributers of this information will be given their proper credit, so please bear with us. This information would be subject to change later when the University of Minnesota Duluth would acquire the frequency and transmitter set up.
