ALE call
An Automatic Link Establishment call (ALE) automatically
selects the best channel to use for sending a call. This removes
the need to send selective beacon calls on different channels to
find the best channel to communicate on.
When you send an ALE call, the ALE controller selects the
best frequency from a preset list of channels and attempts to
establish a link with the other station on that channel. If it
fails, it selects the next best channel and tries again. This
process repeats until a link is established or there are no more
channels to try.
ALE calls allow you to use both numeric and alphanumeric
station addresses. A numeric address is a 6-digit number or
less. An alphanumeric address is either a number greater than
six digits or an address containing one or more of the
characters ‘A–Z’, ‘@’ and ‘?’. Maximum length is 15
characters.
To set up your transceiver’s alphanumeric address, refer to
the HF SSB transceiver reference manual, Chapter 5, ALE
alphanumeric address setup.
When you call an alphanumeric address, your alphanumeric
address is used in the call to identify your station.
When you call a numeric address, your numeric address is
used in the call to identify your station (set up in the selcall
group assigned to the current channel).
For further details, refer to the 9300 ALE controller user
guide (Codan part number 15-04046).
