 Before construction could begin on the new facilities, Mexican approval of the request would need to be obtained, due to the station's proximity to Mexico.KVAW would have to be broadcasting on its final post-transition channel by the end of the DTV conversion, June 12, 2009, and since the FCC had changed the allocation from channel 18 to channel 24, it was no longer authorized to broadcast on channel 18.The station filed for Special Temporary Authorization (STA) to continue operations on channel 18 following June 12, 2009, but that authorization expired August 18 and would need to be renewed.
