Rock Solid Basics:
ALE (Automatic Link Establishment)
The built-in ALE system automatically selects the bestchannel and establishes a communication link. ALE
provides interoperability with other 2G ALE radios
using MIL-STD-188-141B and FED-STD-1045A ALE
standards. ALE individual call, net call, sounding,AMD (Automatic Message Display) and LQA (Link QualityAnalysis) polling are available.

Selcall (Selective Calling)
The IC-F8101 provides CCIR493-4 based 4-digit and6-digit open standards Selcall, widely used in HF
networks and HF calling systems. Supported Selcall
functions include: selective calling, phone call, message call, position call, status call, emergency call andchannel test call. For security, the owner passwordenabled stun feature can remotely disable the radio
operation and the radio can be GPS tracked.

and the CFU-F8100 cooling fan unit has been tested
to MIL-STD-810-G and IP54 ratings. Also, connection
cables and connectors are IP54 water resistant.

125 W* of Powerful RF Output
With the fanless design, you get 125W* output with full
duty cycle operation in voice mode or in data mode amaximum 5 minutes of continuous transmission (25%duty cycle). When used with the CFU-F8100 optional
external cooling fan unit, the IC-F8101 provides full
duty cycle data and voice mode operations for absolute reliability during long continuous transmit cycles,
or for operation in hot climates.
* 100W for Australia versions.

Compact and Durable
Optional CFU-F8100 fitted
to the rear panel.

The IC-F8101 has
a durable, enclosed
structure securely
sealed from the elements, in a stealthy
black compact package. The IC-F8101

BITE (Built-in Test Equipment) Function
You can check the transceiver’s internal condition byusing the BITE capability. Auto, logic, receiver, andtransmitter are checked.

A Benchmark for Ease and Convenience:
User Friendly Operation

Clear Talk Noise Reduction

The IC-F8101 is designed for simple, straightforward
operation. The Administrator/User feature can limit
the functions that are accessed by the User. The
Administrator can enter the operating frequency andassign memory channels from the front panel or theremote control microphone.
The following functions can be assigned to the [I], [II],and [III] soft key buttons: Main menu, Manager menu,Set mode, Selcall address list, RX history, and TX
history.

The clear talk feature separates signals from noiseusing the DSP and gives you clearer audio at thetouch of a button.

Mute Functions
The IC-F8101 has 3 types of mute functions: callsquelch, S-meter squelch and syllabic voice squelch.
Call squelch opens the squelch only when receiving aSelcall or ALE call sent intentionally to this station andprovides quiet standby.

Digital Signal Processor (DSP)
Function button menus are shown at the bottom of the display

The latest DSP technology improves both the transmitter and receiver performance. The digital IF filter
provides flexible filter settings for narrowband signals.

Various Accessories:
GPS Receiver Connection

USB Port for PC Connection

When connected to the UX-248
optional GPS unit, the IC-F8101
can send current position data toother stations and can be usedwith a AVL (Automatic VehicleLocation) system.

The IC-F8101 can be connected to a PC througha USB port for HF Email, CI-V remote control andmodulation input.

Rear Panel View
Optional UX-248Data Communications
The IC-F8101 has an internal expansion slot for anoptional RapidM TC4 or TC4-LP Data Modem Module*1.
This provides HF Email capability connecting to a PC
with Email software from RapidM. In addition, the TC4LP has optional functions including 2400 bps MELPe/
TWELP Vocoder and 256-bit AES encryption*2.
