What are the rules in giving the legal I.D. in Mexico? Some stations give it at the top of the hour, call letters and city. Some don't. Some give it at the bottom of the hour. And I noticed XETRA-FM Tijuana, which is an English-language station aimed at San Diego, has a recorded female voice say the call letters in Spanish but instead of the city, she gives the state's name. "XETRA-FM, Baja California, Mexico." Or at least that's what I heard a few years ago when I was in San Diego. An earlier thread discussed how "City of License" isn't something used in Mexico as it is in the U.S.
