interference between incompatible modes.

Notes:
1)
Significant
regional
variations in
both current
band
utilization
and the
intensity
and frequency
distribution
of noise
sources
preclude
one plan that
is suitable
for all
parts of the
country.
These
variations
will
require
many
regional
frequency
coordinators
to maintain
band plans
that
differ
in some
respects from
any national
plan. As
with all
band plans,
locally
coordinated
plans
always
take precedence
over any
general
recommendations
such as a
national band
plan.
2) May
be used
for
either
repeater
inputs or
weak-signal
as regional
needs
dictate
3)
Division
into
channels
and/or
separation of
uses
within
these
segments
may be
done
regionally
based on
needs and
usage,
such as for
2
MHz-wide
digital
TV.
4) These
segments
may also be
designated
regionally
to
accommodate
alternative
repeater
splits.
5)
Simplex
FM
calling
frequency
927.500 or
regionally
selected
alternative.
6)
Additional FM
simplex
frequencies
may be
designated
regionally.
