These pairs are available for the
coordination and assignment of analog FM repeaters.
Their coordination
and assignment is determined using nominal FM coordination guidelines
and
other considerations, and those pertinent to co-channel and adjacent
channel assignment.

IMPORTANT
NOTE: = Frequencies marked with * are
permitted for simplex use as long as it does
not cause interference to
nearby repeater inputs. Please be aware that SERA coordinates
some of
these frequencies as repeater inputs in some areas. Check the repeater directory in your
area to see
if any such repeaters are present.

that SERA coordinates some of

present. The use of these
frequencies for D-Star operation, whether
for simplex or repeater
inputs, may impact FM simplex and repeater operations and their
selection
should be carefully considered.
