6.CTCSS (Continious Tone Coded Squelch System)
License free radio's operating on the 462 MHz frequency band, like
the Twintalker , have 22 available radio channels. If there are many
radio'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, 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.There are two kind of subchannels :
• Continuous Tone Coded Squelch System (CTCSS)
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.
