US Border Patrol, Customs?
 

I live ~1 mile north of the Mexican border, and there are plenty of Federal
agencies operating in the area. I've been at it for days, but can't seem to
get anything except fire, police, etc on my Pro-2026.

Does BP, Customs, INS, etc., operate on bands outside of the reach of this
scanner?

Anyone got any frequencies handy? The ones I've seen on the web are already
programmed into my scanner, but are always silent...
