Set up a telex call
Set 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.
To set up the transmission mode, do as follows:
1. From the main menu, select Ca
ll.
The system must be configured and enabled before use. See
Before you start on page 6.
You can enable the use of Cyrillic characters on screen under
System > Settings > Cyrillic characters. For details, see To
use Cyrillic characters on page 26.
If Telex is not selected in the MF/HF radio you get a warning
that the radio is occupied. Use the Mode button on the radio
to switch to Telex.
