how long does WJUV have to get their signal on the air before the FCC yanks the license?
April 16, 2013.
They informed the FCC on April 19th that the station had gone dark four days earlier. They requested, and received, Special Temporary Authority to remain off until the end of November. That authority may be renewed if they request. However... The Communications Act requires the FCC to revoke the WJUV license if the station remains off the air for more than a year.
