Multiple-band, multiple-mode
HF to 1200MHz Multi-band in one transceiver
The IC-9100 fully covers the HF/50, 144, 430/440 amateur bands in multiple modes. By

installing the optional UX-9100 1200MHz band unit, you can be operational on the 1200MHz

band immediately.
Independent dual receivers

The IC-9100 has two independent receivers in one radio and receives two different bands

simultaneously (See the right table for available main and sub band combinations). In

addition, the main and sub-band audio can be controlled with independent volume and

squelch knobs, and received audio can be heard separately when external speakers are

connected.

Satellite mode operation
The satellite mode synchronizes the uplink (transmitting) and downlink (receiving)

frequencies, and tracks the frequencies in the same tuning step. This function matches both

normal and reverse mode satellites. Compensation of the Doppler effect can be performed

easily. 20 alphanumeric satellite memory channels store frequencies, mode and tone

settings for quick set-up.
Optional D-STAR DV mode (Digital Smart Technology for Amateur Radio)

The optional UT-121 provides D-STAR DV mode digital voice and low speed data

communications. Linking of D-STAR repeaters over the Internet allows you to communicate

virtually anywhere. In addition to 144MHz, 430/440MH and 1200MHz band, the D-STAR DV

mode can be used in 28MHz and 50MHz band simplex mode.
D-STAR DR mode operation makes it easy to acess D-STAR repeaters
GPS position reporting functions (External GPS receiver can be connected via data 1

connector. Also, position data can be entered manually.)
One-touch reply function

Digital call sign squelch
Received call sign record
Automatic received message display
RTTY demodulator and decoder
The built-in RTTY demodulator and decoder allow you to instantly read an RTTY message on

the display. No external units or PC required. The built-in tuning indicator visually helps in

critical tuning.
Ample CW functions
All of the following CW capabilities are included in the IC-9100:
4 channels of keyer with 70 characters of transmit memory per channel
Multi-function electronic keyer with adjustable keying speed from 6-48 wpm, dot-dash ratio

from 1:1:2.8 to 1:1:4.5 and paddle polarity
Bug keyer and full break-in function
Basic technologies that support the IC-9100
Double conversion superheterodyne
Much like the technology in Icom's high-end HF transceivers, Icom has used a double

conversion superheterodyne system* and an image rejection mixer in the IC-9100. The IC-

9100 has dedicated receiver circuits from the antenna connector to the 2nd image rejection

mixer for each band, and this improves inband IMD characteristics by simplifying the

electronic circuitry.
*A triple conversion system is used for the 1200MHz band.

+30dBm class third-order intercept point
Using receiver design techniques introduced in Icom's highest grade HF transceivers, the

IC-9100 has an IP3 of +30dBm (typ.) in the HF bands. In the VHF/UHF bands, the IC-9100

also provides improved IP3 performance over the previous models.

Three first IF filters (3/6/15kHz) for HF/50MHz band
The IC-9100 comes with a built-in 15kHz 1st IF filter and can accept up to two optional filters

(3kHz FL-431 and 6kHz FL-430). By changing the first IF filter width according to the

operating mode, the desired signal is protected from adjacent inband signals at the later

stages. The 3kHz first IF filter is especially effective in the CW and SSB modes.
Built-in antenna tuner for HF/50MHz band

The internal antenna tuner automatically tunes for low SWR in the HF and 50MHz bands.

Once you transmit on a frequency the tuner can instantly retune the frequency using its

built-in memory.
Antenna connectors
Two antenna connectors for HF and 50MHz bands, with an automatic antenna selector, and

one each for 144MHz, 430/440MHz and 1200MHz*are included in the IC-9100.
With optional

UX-9100.
High frequency stability
A high stability TCXO crystal oscillator provides ±0.5ppm of high frequency stability over a

wide temperature range (0°C to +50°C). This allows for a long steady operating time in the

RTTY or SSTV modes.

HF/50MHz, 144MHz 100W, 430/440MHz 75W
The IC-9100 uses high efficiency power amplifiers, and large heat sink, providing stable

output power, even during long periods of operation.
DSP features and functions
32-bit floating point DSP and 24-bit AD/DA converters
The heart of the IC-9100 is the proven combination of the 32-bit floating point DSP and 24-

bit AD/DA converters. This powerful combination supports many digital processing features

such as modulation/demodulation, IF filter, twin PBT, AGC, noise blanker, noise reduction,

manual and auto notch filters, speech compressor, RTTY demodulator/decoder functions.

AGC loop management
Digital IF filters, manual notch filter and other digital functions are incorporated in the AGC

loop management controlled by the DSP unit. The AGC effectively works for the desired

signal and rejects blocking by strong adjacent signals out of the filter passband. The AGC

time constant presets (slow, medium and fast) give the flexibility and speed needed for

working pile-ups.
Digital IF filter
The IC-9100 DSP allows you to "build your own" digital IF filter. you can quickly choose

bandwidth, shape factor, and center frequency, so that you can work that rare DX station.

Three filter memories allow you to change filter settings instantly, a great help during

contesting or other tough conditions.
Digital twin PBT and IF shift
After "building your own" digital IF filter, you can use the digital twin Passband Tuning (PBT)

to shift and narrow the IF passband until the interference is gone and you can clearly hear

that weak signal.
Noise reduction
The 16-step variable noise reduction can significantly enhance the receiver's signal-to-noise

ratio, giving you a clean, clear audio signal that may make the difference between making

the contact or not.
Noise Blanker
The digital noise blanker reduces interference from pulse-type noise such as engine ignition.

The noise blanker provides significant reduction of pulse-type noise. The noise blanker

allows you to change the threshold level as well as blank duration parameter and attenuation

level.
Manual notch filter and auto notch filter
The manual notch filter controlled by the DSP has extremely sharp characteristics and

provides more than 70dB of attenuation. The notch filter width is selectable from 2 types,

allowing you to select the suitable filter width for the operating mode and band. It eliminates

persistent beat tones without affecting the AGC loop function. In addition, the automatic

notch filter tracks and eliminates two or more interfering signals, such as beat signals and

carriers or tones from digital signals.
Sophisticated operation with expansion capabilities

Large, multi-function LCD
The large, multi-function LCD displays frequency, 9-character channel name, channel

number, multi functional meter (includes S-meter, RF output, SWR and ALC level) for both

the main and sub bands vertically. The dot-matrix portion of the LCD shows the following

items:
Channel name
Function key assignment
Band scope
RTTY decoder screen
Memory keyer contents
Graphical SWR scale
D-STAR call sign, message, DR list
GPS position information
Up to 424 memory channels *
Each band (HF/50MHz, 144MHz, 430/440MHz and 1200MHz*) has a total of 99 memory

channels for storing frequencies, mode and other information. The IC-9100 has 6 scan edge

channels for programmed memory, and a call channel for each band.
Sophisticated operation with expansion capabilties
USB connector for PC control
The IC-9100 has a standard type B USB connector and can be connected to the PC.

Modulation input, audio output, RTTY demodulatior output and CI-V command can be

controlled via the USB cable. Also, the conventional CI-V remote control jack is built in to the

IC-9100.
