I don't understand all this speculation about the location of YS... http://www.spynumbers.com/YosemiteSam.html states quite unequivocally that the FCC DFed it as being near Albuquerque NM in December last year. From the pattern of reception here in southern CA I see no reason to say that it's moved since then. As to the purpose of it, well that's another matter! Dan ac6ao / g3ncr
