I need to clarify my earlier post. KXOL has been off the air (no signal at all, not even a dead carrier) since at least 14:00 local this afternoon. When I went out to my truck on break tonight at around 8:00 PM, another Spanish language station from California was audible on 1660. Given the fact that the owner of KXOL has put so much effort into trying to get the FCC to reinstate KXOL's license, I can't believe he would just let the station go dark unless he was forced to. Of course it's entirely possible that KXOL went dark because someone didn't pay the electric bill and Rocky Mountain Power pulled the plug.
The fact that an FCC agent from the Denver District Office tried to inspect the station in August 2013 and found that their phone had been disconnected and the main studios moved without notifying the FCC probably doesn't help their cause either. I'd say Mr. Vicente or one of his staff (if there is any) should have become familiar with the FCC's rules governing broadcast stations beforehand. Que Sera Sera!
