Selecting the CTCSS code

CTCSS = Continuous Tone Coded Squelch System.

All the calls on walkie-talkies which occur within the range of reception are signalled. A condition for this is that all the walkie-talkies are set to the same channel. To prevent mutual interference, a CTCSS code can be defined for the set channel.

Each CTCSS code complies to a specific audio frequency transmitted by the walkie-talkie. Communication between the subscribers is only then possible when both parties are using the same channel and CTCSS code. An exception is CTCSS code “0”. In the case of this setting, all the calls on the set channel can be heard regardless of the CTCSS code. To be able to participate in the radio communication, it may be necessary to switch from CTCSS code “0” to the CTCSS code being used.

If you want to communicate with the walkie-talkies which are not using a CTCSS code, you must select CTCSS code "0" on your walkie-talkie.
