FOREWORD
Thank you for making the IC-9100 your radio of
choice. We hope you agree with Icom’s philosophy of
“technology first.” Many hours of research and devel-
opment went into the design of your IC-9100.
FEATURES
❍The IC-9100 fully covers HF to 1200 MHz*1multi-
band in one transceiver
❍Independent dual receivers in one radio; receives
two different bands simultaneously
❍Optional D-STAR (Digital Smart Technology for Am-
ateur Radio) allows you to operate in the DV mode*2
for digital voice and low speed data communication.
Linking of D-STAR repeaters over the Internet al-
lows you to communicate virtually anywhere.
❍Satellite mode operation
*1 The optional UX-9100 is required for 1200 MHz fre-
quency band operation.
*2 The optional UT-121 is required for the DV mode opera-
tion.
IMPORTANT
READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operate the
transceiver.
SAVE THIS INSTRUCTION MANUAL. This
manual contains important safety and operating
instructions for the IC-9100.

FCC INFORMATION
• FOR CLASS B UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equip-
ment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance
with the instructions, may cause harmful interference
to radio communications. However, there is no guar-
antee that interference will not occur in a particular
installation. If this equipment does cause harmful
interference to radio or television reception, which can
be determined by turning the equipment off and on,
the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
 •Reorientorrelocatethereceivingantenna.

PRECAUTIONS
RDANGER HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
RWARNING! NEVER operate the transceiver
with a headset or other audio accessories at high
volume levels. Hearing experts advise against continu-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
RWARNING! NEVER operate or touch the
transceiver with wet hands. This may result in an
electric shock or damage to the transceiver.
RWARNING! NEVER apply AC power to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
RWARNING! NEVER cut the DC power cable
between the DC plug and fuse holder. If an incorrect
connection is made after cutting, the transceiver may
be damaged.
RWARNING! NEVER apply more than 16 V
DC to the [DC13.8V] socket on the transceiver rear
panel, or use reverse polarity. This could cause a fire
or damage the transceiver.
RWARNING! NEVER let metal, wire or other
objects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
RWARNING! Immediately turn OFF the trans-
ceiver power and remove the power cable if it emits
an abnormal odor, sound or smoke. Contact your
Icom dealer or distributor for advice.
RWARNING! NEVER put the transceiver in
any unstable place (such as on a slanted surface or
vibrated place). This may cause injury and/or damage
to the transceiver.
CAUTION: NEVER change the internal settings of
the transceiver. This may reduce transceiver perfor-
mance and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might
damage the expensive final devices.
The transceiver warranty does not cover any prob-
lems caused by unauthorized internal adjustment.
CAUTION: NEVER block any cooling vents on
the top, rear, sides or bottom of the transceiver.
CAUTION: NEVER expose the transceiver to
rain, snow or any liquids.
CAUTION: NEVER install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be damaged.
DO NOT use harsh solvents such as benzine or
alcohol when cleaning, as they will damage the trans-
ceiver surfaces.
DO NOT push the PTT switch when you don’t actu-
ally desire to transmit.
DO NOT use or place the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOT place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT place the transceiver against walls or
putting anything on top of the transceiver. This may
overheat the transceiver.
Always place unit in a secure place to avoid inadver-
tent use by children.
BE CAREFUL! If you use a linear amplifier, set
the transceiver’s RF output power to less than the
linear amplifier’s maximum input level, otherwise, the
linear amplifier will be damaged.
BE CAREFUL! The transceiver will become hot
when operating the transceiver continuously for long
periods of time.
USE only the specified microphone. Other manufac-
turers’ microphones have different pin assignments,
and connection to the IC-9100 may damage the
transceiver or microphone.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from
the magnetic navigation compass to prevent errone-
ous indications.
Turn OFF the transceiver’s power and/or disconnect
the DC power cable when you will not use the trans-
ceiver for long period of time.
For U.S.A. only

not expressly approved by Icom Inc., could void your
authority to operate this device under FCC regula-
tions.

DAbout the D-STAR system
In the original D-STAR (Digital Smart Technologies for
Amateur Radio) plan, JARL envisioned a system of
repeaters grouped together into Zones. A zone would
be a group of up to 4 repeaters, linked by 10 GHz
“backbone” microwave Link repeaters.Each individual
repeater would be call an Area repeater, and would
be the Access repeater to begin communications.
Calls could be made to other Area repeaters within
the Zone, using the backbone Link repeater system.
One of the repeaters in the Zone would have an In-
ternet connection, and so in addition to being an Area
repeater, it also became the Zone Gateway repeater.
The Internet gateway provided a way to communicate
to other Zones, giving access to the Area repeaters
within them, and eventually to the entire world.
Call signs are the heart of D-STAR operation.Four call
signs are used:
•MY :Thisisyourowncallsign.Youenteritonceand
then basically leave it set, with only a few ex-
ceptions.
•UR :ThisisyourDestinationcallsign;thatoftheac-
tual ham or repeater you wish to contact.CQC-
QCQ can also be used to make a general call.
•R1 :ThisistheArea/Accessrepeatercallsign;the
one you enter to begin your D-STAR repeater
communication.
•R2 :This is the Link/Gateway repeater call sign;
the repeater and Internet connection you go
through when you want contact a ham, or an-
other repeater, anywhere else in the world.
Call sign routing, one of the main features of D-STAR,
allows hams to contact other hams, or other repeat-
ers using just the ham’s or repeater’s call sign. The
D-STAR system will automatically route your signal to
the desired ham or repeater. Call sign capture allows
hams using an Icom radio to “capture” a call sign and
automatically program their radio for a reply.
Like other communication modes, you can operate
simplex D-STAR with other hams, for direct commu-
nication.
See pages 85 to 120 for the D-STAR operation de-
tails.
NOTE: The optional UT-121 is required for the D-
STAR operation with the IC-9100.

(Gateway)
Area:
The Area is the communication range
that is covered by a single repeater.
The repeater is called an area, or
access repeater in the D-STAR system.
Zone:
The Zone is composed of several areas, that are linked
by a 10 GHz microwave link.
Areas 1 to 4 and 5 to 8 make up a zone in the example
above.
Link repeater:
The microwave (10 GHz) link repeater
provides linking with another repeater
site (Area) for zone construction.
Gateway repeater:
Gateway repeaters provide communications between
different zones via the internet.
Repeater 3 and 6 are gateway repeaters at the
example above.
