CALL TYPES
406 ENVOY™ TRANSCEIVER REFERENCE MANUAL
If you have the FED-STD-1045 ALE/CALM option installed, you can use the global
ALL address syntax (@?@) with the Message call type to send a call to a group of
stations using an ALE/CALM HF network. If you have the MIL-STD-188-141B ALE
option installed, you can use the ALL, ANY, Group Selective, NET, or Wildcard
address syntax with the Message call type to send a call to a group of stations using
an ALE/CALM HF network.
Message calls are automatically answered by a called station so an operator is not
required to take any action. If you make a Message call type using an ALE/CALM HF
network, the link terminates immediately after the message is sent. Messages you
receive are displayed on the screen, if permitted, and stored in the Call History.
