I believe I received a mediumwave station from Mexico this evening. The frequency is 1630 khz, and I heard an announcer speaking in spanish, mentioning Tijuana and Mexico. I heard what sounded like an identification at the top of the hour, but I couldn't understand it since I don't know spanish.
Can anyone suggest possible identifications for this station? I haven't found any lists of Mexican AM stations that include a station on 1630 khz.
