This is
a "grab
bag" of
miscellaneous
radio
communications,
mainly
beacons
and
navigation
aids.
You may
hear
several
transmitters
that
sound
like
chirping
crickets;
these
are
floating
beacons
used to
mark
fishing
and
offshore
oil
exploration
locations.
In
Europe
you can
hear
Coastal
Radio
stations
in this
band.
Best
time to
listen
would be
during
the
nighttime
hours.
Most
two-way
communications
