RM2-ALE: HF Voice Controller [Prelim.]
ALE Voice Controller
ALE Voice Calling
The RM2-ALE is a mobile voice controller for use
with HF radios. The unit automates and optimizes
multi frequency voice communications over long
distance HF links. Typical applications include
emergency & disaster relief, governmental and nongovernment (NGO). The unit is suitable for use in
mobile & marine environments.
To make a call the user enters the required remote
station address on the DTMF microphone. If the call setup
is successful the RM2-ALE signals the remote user by
sounding a ring tone on the internal buzzer or external
speaker. The remote user answers the call and normal
voice communications commences. When the system is
not busy with a call, the internal and external speakers
are muted.
Link Establishment
The ALE Controller performs all the basic protocol
functions for individual calling, one-to-many calling,
sounding, channel selection and scanning.

ALE Network
Using an ALE network over a number of frequencies
offers HF voice users a much higher level of
connectivity compared with using a single frequency.
The ALE voice controller removes the need for
complicated HF propagation prediction charts, time
schedules and HF channel monitoring.

When not otherwise committed, the ALE Controller
continually scans the pre-selected set of channels,
listening for calls. When the self address is detected and
a link is established voice communications can
commence.
For link set-up, the RM2-ALE calls first on channels with
the best Link Quality Analysis (LQA) score. If the LQA
score is outdated, the system will poll other stations to
update the score before selecting the call channel.
The RM2-ALE HF Voice Controller supports Occupancy
Detection (OD) and Listen before Transmit (LBT) (2nd
Generation ALE).
HF Radio Control Support
The RM2-ALE automatically controls an HF radio in order
to establish communication links with other HF stations.
No operator intervention is required. The RM2-ALE
supports the following radios:
•
•
•
•
•
ICOM Professional and Marine
Kenwood TK-90, TS-50, TS-480,
TS-2000 (TBC)
Yaesu Vertex Standard VX-1700,
System 600
CODAN NGT
Barrett 940
New radio models are added from time to time on
customer request. Please contact RapidM for more
information on specific radio support.
ALE Network Configuration
To assist with the configuration of ALE networks, RapidM provides a 2G ALE network configuration PC utility,
which clones a basic configuration onto a number of RM2-ALE units, leaving only the self address parameters to
be set individually. The utility also produces a print-out of a phone book (names, station id’s) for easy reference.
The ALE configuration can be saved in one of ten available custom preset memories in the RM2-ALE unit.
