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 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.
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 on of these 38 available
tones. Due to fi ltering, these tones will generally not be audible so they
will not disturb the communication.
