Mixed
Public
Safety
Unlike the lower bands, frequencies
in
the
800
MHz band are not allocated
by the
FCC
to specific services such
as
Police,
Fire,
Ambulance, and so
on.
I n 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
are conventional. Five channel sys-
tems might use trunking, but
all
sys-
tems with more than five channels
must use trunking.

You might discover some of your regular stations on another frequency that
is
not listed. It might be what
is
known
as
an
"image." For example, you suddenly find 453.
2750
also being heard on 474.
8750.
To see if it is
an
image,
do
a little math.
Take the intermediate frequency of
10
.7 MHz and double
it.
Then, subtract
it
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 21.4MHz below the tuned frequency. This
is
rare, and the image signal
is
usually cleared whenever a
broadcast on the actual frequency
is
in
progress.
