KWWF/22 (Waterloo) has gone off the air "due to financial difficulties," according to a notification of suspension of operations filed with the FCC. KWWF, owned by Stratus Communications, had carried Untamed Sports TV. The ten-year-old station has a long history, having served as a UPN affiliate and a beta tester for Retro Television Network before going silent from mid-2009 to mid-2010.
