6. CTCSS(Continious Tone Coded Squelch System)
License free radio’s operating on the 446 MHZ frequency band
have 8 available radio channels. If there are many radio’s users in
your neighbourhood, there is a chance that some of these users are
operating on the same radio channel.
To prevent that you receive signals from other users, sub-channels
have been integrated.
Two radio’s will only be able to communicate with each other when
they are operating on the same radio channel and when they have
selected exactly the same sub-channel.
When using CTCSS, a low frequency tone (between 67 and
250 Hz) will be transmitted along with the voice signal. There are
38 available tones to choose from. You are free to choose one of
these 38 available tones. Due to
fi
ltering, these tones will generally
not be audible so they will not disturb the communication.
