/chatmode 0 – This command is the default as far as Chat goes on Hamsphere. When you type a message in the Chat Box, the message can be seen by everyone. Type as often as you'd like but please keep in mind that all users can see your message so be polite. Refrain from using Obscenities at any time.

/chatmode 1 – Set Chat Mode 1 and all your messages in the Chat box will be seen ONLY on the Band you are currently on.

/chatmode 2 - Set Chat Mode 2 and all your messages in the Chat Box will be viewed only by the users on the frequency you are currently on.
