2-12.3 Receiving and Transmitting Calls in ALE Mode
The Micom-Z supports the following types of ALE calls:
• Individual call – call directed to a specific station.
• Net call – call directed to a net (a net is a preprogrammed group of stations).
• Group call – call directed to a group of stations.
• AllCall – call directed to all other stations simultaneously (broadcast call); can also be used as a
distress call.
• AnyCall – call directed to all other stations simultaneously, usually used to detect new stations.
• Wildcard call – call simultaneously addressed to a selected group of stations within a net, with
wildcards used within the address to specify the desired stations. For efficient use of wildcards,
an appropriate station naming plan must be in place.
• Self call – call using the station’s own address, generally used for test purposes.
• Bidirectional call – request for updating the LQA score with another station or stations.
• Sounding call – used to build a link quality database. This database stores ongoing information
on the current quality of the various channels programmed for use by your radio.
All types of calls, except for sounding calls, can also carry messages.
Using the ALE message service, you can also request remote stations equipped with GPS receivers to
send their position. Moreover, if the GPS receiver of your radio is operational, you can also send your
position to other radio sets.
During ALE calls, a link is established between the stations participating in the call. During the link
state, the radio operators have various options, many of them similar to the options available in the
Channel mode. For a description of the link options, see pages 2-31 to 2-34.
2-12.3.1 Receiving Calls in ALE Mode
When your Micom-Z receives a call, it displays its type and the source
address.
You are also notified when a message is attached: if a message is received,
the name of the calling station is preceded by an exclamation mark.
For any type of call, if the ALERT attribute is programmed to YES, you
will hear the alert tone when a message is received.

Receiving a net call:
When your radio receives a net call (i.e., a call addressed to all the stations in your net), the display
flashes a net call alert that alternates the words NET CALL with the calling station name.
