In Arma 3, chat, radio, VON and markers all use the same channel ID system. However, channel IDs for custom channels behave a bit differently. This is explained in the table below.

Channel Explanation

Channel ID Channel Name Visible To Additional Information
-1 None Is used when a marker is created with createMarker and the channelID parameter was not defined. Markers in "none" channel are visible in all other channels as well.
0 Global All players.
1 Side Content[1] is only visible to the side of the player who created it.
2 Command
3 Group Content[1] is only visible for the players in the group of the player who created it. This channel cannot be disabled. It's the default fallback channel if all other channels are disabled.
4 Vehicle Content[1] is only visible to the vehicle's crew.
5 Direct To players in close proximity.
6 - 15 Custom Channels Content[1] will only be available for players which have been assigned to this channel. See radioChannelAdd Custom channels can be created on the fly. See radioChannelCreate.
The custom channel ID returned by radioChannelCreate is going to be in a range from 1 - 10 (0 if failed). Internally, these numbers are converted to the channel IDs 6 - 15 which are reserved for custom channels.
Channel ID 6 7 8 9 10 11 12 13 14 15
Custom Channel ID 1 2 3 4 5 6 7 8 9 10

Custom Channel ID Example

// Create custom channel
_customChannelID = radioChannelCreate [[0.96, 0.34, 0.13, 0.8], "Q-dance Radio", "%UNIT_NAME", [player]]; // _customChannelID is 1
// Switch current channel of the player to the newly created channel.
setCurrentChannel 6; // Note the channel ID used here. Even though the ID returned by radioChannelCreate is 1, we have to use 6 as channel ID. See table above.
// Let us use this channel for a message
player customChat [_customChannelID, "Hi, I am a custom chat message"]; // Since this command uses the customChannelID we have to use 1 (_customChannelID) here
Always be aware of what kind of channel ID you are currently working with and what channel ID is expected by the command you are using. See Command Group: Custom Radio and Chat for commands which expect a customChannelID!
