Appendix A micomTrooper 3 5-50 Watt HF-SSB Backpack Transceiver
131
micomTrooper 3 is part of the MICOM-3 family of HF-SSB radio sets; it has compatible characteristics
and uses the same operating procedures as other MICOM-3 transceivers. Therefore, this manual
covers only procedures specific to micomTrooper 3; the other procedures, which are common to the
whole MICOM-3 product line, are described in the previous sections.
Purpose and Use
micomTrooper 3 is a backpack version of the robust MICOM-3 mobile radio. For backpack
operation, micomTrooper 3 is powered by a lightweight Lithium Ion rechargeable battery, has
selectable power output of 5 to 20 W and high sensitivity, and uses a 1.5 meter (5 ft) flexible steel
blade whip antenna matched by a built-in automatic antenna tuner unit. When necessary,
micomTrooper 3 can be programmed to reach a power output of 50 W, and can also be used with
dipole, long-wire and many other types of broadband antennas for static operation.
The micomTrooper 3 capabilities provide reliable long-range HF-SSB radio communications in a
rugged yet lightweight backpack configuration. Designed to meet the needs of users who carry out
on-foot operations in remote areas, it is built to withstand years of shock and vibration as well as
severe weather conditions. micomTrooper 3 is certified for dependability and durability, and
complies with US standard MIL-STD-810F.
micomTrooper 3 is equipped with a military-type handset, whip antenna, cables and connectors,
delivering superior quality in a radio priced to fit the needs of a wide range of organizations. For
backpack operations, micomTrooper 3 is carried in a convenient, lightweight harness that completely
envelops the transceiver.
The durable aluminum frame of the harness protects against damage and allows placing the
transceiver on ground for static operations.
Equipment Description
micomTrooper 3 Functional Description
micomTrooper 3 is an advanced, highly backpack-portable HF-SSB transceiver that provides a
complete solution to the communication requirements in the crowded HF band. micomTrooper 3
has an automatic antenna tuner, which supports a wide range of antennas, including a light-weight
1.5 meter (5 ft) whip for portable (backpack) operation. The whip antenna consists of a flexible steel
blade that bends without damage when striking an obstacle, and can also be easily folded for storage.
Dipole, long wire, and many other types of antennas can be used for static operation.
micomTrooper 3 provides voice, data, and telegraphy (CW) communication. Extensive use of digital
signal processing ensures high performance and supports as a standard many advanced features, e.g.,
digital noise blanking, and offers as options features such as embedded vocoder, data modem and
encryption. Moreover, new features and improvements can be easily added by software updating.
To ensure the best possible communication reliability and quality, micomTrooper 3 uses automatic
frequency management and automatic link establishment (ALE), and is JITC-certified to FED-1045
and MIL-STD-188-141B. In addition, the ALE function also provides Automatic Message Display
(AMD), that enables operators to exchange preprogrammed messages while establishing a link.
The transmit output power is operator-selectable (5, 10 or 20 W). When used in a backpack
configuration, the operator can reduce the transmit power and thus increase battery life when the
communication conditions do not require the maximum transmit power (20 W).
