why would a scanner include the 800-900mhz frequencies?
does anyone know what the 800 and 900 mhz frequencies are used for?

Thanks

right becuase ive been trying to tune into those 800-900 frequencies on selected mobile towers from the acma database, and (not that il hear anything becuase its scrambled) basicly theres no transmittions on those frequencies weather they are scrambled and high pitched encrypted sounds or not.
