ALE relieves you of the burden of trying to manually detect and
compensate for random changes in the ionosphere and of
searching for a good channel to use. It lets you concentrate on
the message to be sent.
During the time when no call is present, the radio is squelched to
reduce noise in the cockpit. After a call is received, a sound like a
phone ringing is heard, the radio un-squelches, and you can com-
mence a normal HF communication. ALE relieves you of the bur-
den of monitoring the radio for the presence of an HF call.
