The MICOM 2 supports the following types of ALE calls in accordance with
•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.

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 19 to 23.
