Direct call is used when you wish to enter a dialogue with a coast station or another mobile radiotelex system (e.g.
a ship). The possibility of a dialogue does not exist in the mailbox call.
In the direct call menu three types of calls are available:
1.ARQ call where dialogue is wanted to a coast station which transmits the free signal when a channel is free to use.
2.ARQ call to a mobile radiotelex system (e.g. a ship), this station does not transmit a free signal.
3.FEC call to one or more stations. NOTE: The FEC call does not give the possibility of a dialogue.
