Unlike the lower bands, frequencies in the 800 MHz band are not allocated 
by the FCC to specific services.  In each area, the channels are licensed
on a first-come, first served basis.  There are two categories for
licensing: Public Safety and Industrial.  Systems using one to five
channels might use trunked service, but all systems with more than five
channels must use a trunked service.

851.0125 - 855.9875...................................Conventional Systems
856.0125 - 860.9875................................Conventional or Trunked
861.0000 - 865.9875........................................Trunked Systems
866.0000 - 869.9999.....................................Reserved-Satellite

You might discover one of your regular stations on another frequency that
is not listed.  It might be know as an "image."  For example,  you suddenly
find 453.2750 also on 474.8750.  To see if it is an image, do a little
math.  Double the intermediate frequency of 10.7 MHz and subtract that
number (21.4 MHz) from the new frequency.  If the answer is the regular
frequency, you have tuned to an image.  Occasionally, you might get
interference on a weak or distant channel from a strong broadcast 21.4 MHz 
below the tuned frequency.  This is rare, and the image signal is usually
cleared whenever there is a broadcast on the actual frequency.
