Of course, we could look the other way and say that many South Texas stations are sort of border blasters. KGBT in Harlingen sends the equivalent of 200 kw to Mexico and I have heard it in Tecamachalco in the Mexico City market interfering with local XEUR a few years ago. .
That station, along with KVNS, can be heard in Houston at times, mostly during critical hours. Quite the little blowtorches the Valley has down there.
There is a difference between being "anal" as you say and being factual
The problem with being "factual" is that there really is no definition as to what constitutes a border blaster. It's all relative, really. What else would you call XHRR, XETRA-FM, or XHTO?
The definition of a border blaster is a station adjacent to the US border with power well in excess of the maximums permitted by our FCC.
Using your own definition makes your prior statement false then.
San Diego is in Zone I-A, which means the FCC only grants up to Class B FM licenses in that area (not counting grandfathered operations, of course). XHITZ and XHRM both exceed the height and power restrictions of a class B radio station.
So technically Tijuana does have border blasters.
Furthermore if we were to strictly use your definition, then that means XEG (which is considered a
former border blaster by most) isn't a border blaster at all. Monterrey is at least 90 miles from the Rio Grande, which isn't
adjacent af all. (Of course, I don't know where exactly XEG's transmitter is, but am I still safe to assume it's not near the border?)
