Starting last Saturday, one of the more less-than world famous, famous
new rock stations 91 X. 91X is broadcast out of Tijuana and 91.1FM is the
kissing cousin of 106.7 KROQ. The signal was drowned out by
a local religious broadcast. Although the government doesn't make mistakes,
a check of the stat sheet seems to reveal that they somehow granted several
new 91.1 FM licenses including one that started recently broadcasting in
what's called the Mexican border zone, even though it's 314km to the border
in Las Vegas, NV. Somebody finally pulled the plug on Thursday after 3-4 days.
After a day or two, I thought maybe it was a pirate broadcast as I never
heard any commercials, but it turns out maybe it was official. I wonder
how much ad revenue 91 X lost because of the mixup.
