6.CTCSS (Continious Tone Coded Squelch System)

License free radio's operating on the 400~470 MHz
frequency band, like the Twintalker , have 8/20/22 available
radio channels. If there are many rad io 's users in your
neighborhood, 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, sub­channels 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.There are two
kind of sub-channels :

Con ti nuo us To ne C ode d Squ elch Sy ste m (CTCS S)

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 filtering, these tones will
generally not be audible so they will not disturb the
communication.
