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.
