USING SUBAUDIBLE TONE SQUELCH (CTCSS)
Some repeaters require that you transmit a subaudible tone to key-up the repeat-
er. You can set your transceiver to transmit any of the 38 standard subaudible
tones.
You
can
also
limit
incoming
calls
by
setting
your
transceiver
to
open
the
squelch only when someone transmits a subaudible tone you set.
