HF SSB transceiver user guide 4-3

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).
