Nancy monitors the speedy delete requests. I tagged the KVMX redirect page for speedy delete in order to move the page and she took care of the move for me (sometimes the admins just delete the page and I have to move it myself). I really think the KBKO page should remain a disambiguate page with a listing for KVMX stating it was formerly KBKO-FM, that way they can still get to the new station if they happen to type KBKO. That's generally how we handle this kind of change.
