A month late, but I used to be forced to listen to country station KMPS at work, and they would play the anthem at noon every day.
When I was on vacation in San Diego, I woke up at midnight on Sunday night to hear boarder blaster (English language alternative rock) XETRA play the Mexican national anthem.
XETRA? Never heard of it.
However, XERA (without the T) and XERF were the Mexican stations that inspired ZZ Top's "Heard It On The X."
I'm just going by the information I found on
Radio Locator.Seattle's The End (KNDD) was started by the owners of XETRA at the time. They brought over Brian Jones as the morning host, and he said that XETRA was the inspiration for Wall of Voodoo's "Mexican Radio." Brian also said that the studio was right next to the transmitter, "Shooting X-rays into your head," due to relaxed work safety rules.
