I finally got KOMO AM 1000 to come in long enough and clear enough the other morning (in Phoenix) that i could hear the 0500 MST / PDT ToH station ID clearly. That’s ~1,100 miles from here, straight line.
There was also some music underneath it, and I’m wondering what station that would have been. It was what I think you call “regional Mexican” music. I had assumed that, since 1000 AM is a clear channel freq, that it was XEOY from Mexico City. That’s ~1,275 miles, straight-line. However, when I have listened to that station’s internet stream, the music is not similar to what I heard. Could it have been XEFV out of Juarez? That’s only supposed to be 1,000 Watts daytime, but I’m uncertain what other station it might have been.
