CTCSS OPTION
WHY USE CTCSS?
CTCSS (Continuous Tone-Coded Squelch System)
is available as an optional add-on to your transceiver.
When CTCSS is turned on, the transceiver transmits
a selected tone with your transmission. This tone is
too low for you to hear, but other transceivers can de-
tect it. If CTCSS is turned on and set to the same tone
on the receiving transceiver, it only receives transmis-
sions that include the tone. This way, CTCSS can
help keep you from hearing other users on the same
frequency.
For example, if two different groups operate trans-
ceivers in the same area on the same frequency but
use a different CTCSS tone, they only hear their own
broadcasts.
Note: CTCSS does not make your conversations pri-
vate. Other users can still hear your transmissions if
they use the same frequency.
