This is an approximate look, to help in searching frequencies on a
scanner or shortwave radio.  Just be aware, having the right frequency
may not be enough, in tuning to a certain frequency.  The time of
day, atmospheric conditions, location, mode you're in (AM, SSB,
Narrowband FM, Wideband FM, etc.), and your equipment, are also equally
important.  You'll find most transmissions are broadcasted in Narrow-
band FM.  Some main exceptions are shortwave (AM & SSB), commercial AM
radio (AM), commercial FM radio (Wideband FM), television (Wideband FM),
citizens band radio (AM & SSB), aeronautical communications (mostly AM),
and some military VHF/UHF (Wideband FM).  Most all scanners will pick a
default mode for you, depending on what frequency band you are in.  But
many scanners also let you manually switch between modes (AM, FM, etc.)
and frequency search spacing (5 khz, 12.5 khz, etc.) if the default
modes are not correct.  Happy Listening!!!

                  Note: Even though listening to cellular
                  telephone calls is technically illegal in the
                  United States, one will usually do better
                  listening to calls on the tower frequencies,
                  as opposed to the handset frequencies.  This
                  is because most cellular phones transmit less
                  than one-watt of output.  

894 - 896                  Aeronautical telephones (handsets).
                  Note: In scanning airplane telephones, you
                  will usually do better listening to the handset
                  frequencies, instead of the tower frequencies,
                  unless you are very near a ground transmitter.
                  But, in any event, call traffic heard on handset
                  frequencies is very scant.
