Amateur Radio ALE






[ January 1st, 2002]

Members of the amateur radio community are currently
experimenting with the use of Automatic Link Establishment
within the Amateur Radio Service.

In order to develop adequate standards for this application,
an amateur radio ALE user group has been formed. The advantage
of a user group is that a common frequency list will be developed
for the HF amateur radio bands, and a centrally-administered
net member list will allow all members of the Amateur Radio
community to work from a common plan.


There is an embedded ALE controller board, which is available
from Frederick Electronics, and may be a solution for use by
our ALE user group.


There are great advantages of the application of ALE signaling
within the Amateur Radio Service for Emergency Communications.
These advantages include:

bulletSelective calling
bulletEliminates the need for participating stations to keep
their radio speakers on at all times in order to receive
a call.

bulletChannel Evaluation
bulletAllows the station itself to keep track of which specific
radio channels are best in order to call another station.

bulletOrderwire messaging/paging
bulletAllows the calling station to leave alphanumeric pages,
also known as "orderwire messages", with the station
being called.
bulletThe called station only need to have their equipment
turned on, and in ALE standby mode in order to
receive orderwire messages.
bulletWithin the ALE protocol, any group of up to 16 members
can have a common net callsign, allowing all members
of a group to be called at one time.



ALE net configuration is being managed by
Ms. Bonnie Crystal - KQ6XA on the HFLINK mailing

There is a master document that will be used by all
active stations who wish to link up via ALE.

The net configuration database is in the database
area of the hflink site.

The object or our testing is to gauge the effectiveness of ALE Selective Call and Linking capability for use in a Local Government/OES/RACES context,  and within a State Military Reserve/National Guard context, in support of mission-critical communications activity.  

The goal is to integrate ALE linking and Channel Evaluation techniques with Field-deployable, mobile, and fixed-site HF data communications
equipment and techniques.


Richard McClung has also uploaded an exhaustive presentation/handbook
covering HF radio and ALE protocol. It is located
