The Micom Pathfinder capabilities provide reliable long-range HF-SSB radio communications in a
rugged yet lightweight manpack 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. Micom Pathfinder is certified for dependability and durability, and
complies with the applicable sections of MIL-STD-810F and MIL-STD-810E.
Micom Pathfinder supports voice and data communications. Micom Pathfinder supports data rates up
to 4800 bps by means of an optional internal (embedded) modem.
Extensive use of digital signal processing (DSP) ensures high performance; a built-in voice quality
system with proprietary DSP algorithms filter out background noise and elevates sound bytes
providing exceptional communication clarity and voice quality. Many advanced features are standard,
such as digital noise blanking and voice-activated digital squelch. Optional features such as embedded
data modem, embedded vocoder, embedded AES encryption, etc., are also available. Moreover, the
addition of new features and upgrading to future technologies are easily made by software updating.
To ensure the best possible communication reliability, Micom Pathfinder Automatic Link
Establishment (ALE) has been certified by the Joint Interoperability Test Center (JITC) to 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 AMD function
is also used in several advanced optional features, such as automatic position reporting (either
operator-initiated or in response to queries) when a GPS receiver is installed, and automatic adoption
of the encryption key used by the transmitting station (provided the necessary key is available at the
receiving station).
1-3. EQUIPMENT DESCRIPTION
This section describes the main equipment units of the Micom Pathfinder radio set.
1-3.1 Micom Receiver/Transmitter
The Micom receiver/transmitter unit performs the following main functions:
• Generates the transmit signals.
• Demodulates the received signals.
• Processes the GPS signals (optional).
• Provides the interfaces to the operator, and to data equipment using Micom Pathfinder for radio
communications.
Figure 1-2 shows a general view of Micom, including its battery box.

Receiver/Transmitter
The Micom is a complete HF/SSB receiver-transmitter, powered by a 14.4 V Lithium-Ion battery
installed in a battery box attached to the rear side of the Micom by two clamps. The box houses the
battery and protects the battery against environmental elements.
