CALL TYPES AND FEATURES
SENDING AMD INFORMATION WITH A CALL
420 ENVOY™ TRANSCEIVER REFERENCE MANUAL
Sending AMD information with a call
NOTE: GPS information is only sent if the GPS Call option is installed.
For interoperability with other transceivers, the Envoy™ Transceiver recognises
special AMD messaging syntax included at the beginning of an AMD message sent
in an HF network with a privacy mode set to Plain. The transceiver accepts and
processes the syntax shown in Table 53. You can also manually enter any of this text
into an AMD message. The syntax shown must be followed by a space, then the
required information.
NOTE: When you send an Emergency call from an Envoy™ Transceiver using
a Plain network, the text #HELP appears in the AMD message of the
receiving vendor transceiver.
NOTE: Calls sent from a Codan HF transceiver to a non-Codan HF transceiver
show the various calls using the AMD alert feature of that transceiver.
