There is, of course, one BIG difference between U.S. and Mexican Stations, and that is a matter of POWER; American Stations are limited a maximum ... a limitation that does not exist under Mexican regulation. X.E.R.F. for example, is licensed to operate on power, and the Department of Communication and Public Works of the Mexican Government has authorized a power increase to . Such power could result in serious interference if wave lengths were not strictly maintained, but the equipment with which X.E.R.F., operates assures its signal to stay "right on the beam." This is something constantly checked by FCC monitor stations, a degree of regulation by the U.S. Government alike that is imposed upon U.S. Stations. Operating on a clear channel, X.E.R.F. is heard nightly in all parts of the fifty States in the United States, Canada and Latin-America.
