Setting up a telex call
Setting up the transmission mode
The Radiotelex system has three transmission modes:
• ARQ (Automatic Repetition reQuest): A mode where two stations can
communicate without breaking the connection. The direction is changed
with an “over” command.
• Selective FEC (Forward Error Correction): A one-way mode to one station.
• Broadcast FEC: A one-way mode broadcast to all stations. E.g. used in
distress situations or for news or coast station traffic lists.
