ICOM IC-7600
HF/50MHz ALL
MODE TRANSCEIVER
ICOM IC-7600
The flagship's linage.
Dual DSP for transmitter/receiver and spectrum scope.
Two separate
32-bit DSP units power the transmitter/receiver and
spectrum scope. These processors give the IC-7600 high
performance comparable to our top-of-the-line IC-7800
and IC-7700, thanks to the combination of dual DSP and
our analog RF design expertise.

104dB dynamic range and +30dBm third-order intercept
point (IP3)
Icom's long years of analog RF circuit experience
combined with the latest digital technology results in
an astonishing 104dB receiver dynamic range and +30dBm
IP3inthe HF bands with-out sacrificing receiver
sensitivity.Even a weak signal adjacent to strong
signals clearly received by the IC-7600 .
Double-conversion superheterodyne dramatically
improves inband IMD
The
IC-7600 employs a double-conversion superheterodyne
system which has an image rejection mixer for the 2nd
mixer stage. When compared to a typical
triple-conversion system, the double-conversion system
is more difficult to implement but it dramatically
reduces signal distortion and provides a high-fidelity
RF signal to the DSP processor.
Dual AGC loops controlled by DSP
The IC-7600 has dual AGC loops, one
analog and one digital, both under DSP control. This
architecture prevents strong adjacent signals from
"pumping" the AGC and allows maximum dynamic range in
the DSP.
Three built-in 1st IF (roofing) filters, including
3kHz The
IC-7600 has three built-in 1st IF (roofing) filters
ahead of the 1st IF amplifier stage. The 3kHz filter is
especially effective in CW and SSB modes to eliminate
overloading caused by strong signals just outside the
passband.
Digital IF filter
The IC-7600 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 while your
competition's still tweaking their transceiver controls.
three filter memories allow you to change filter
settings instantly, a great help curing contesting or
other high-rate operating.
Digital twin PBT
After "building
your own" digital IF filter, you can use 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.
Digital notch filter
 Signals
such as heterodynes and AM carriers can be eliminated
with automatic notch filter technology, making
interference from RF sources such as beat signals and
RTTY signals a thing of the past. You can also choose
three shape factors for the notch filter, to optimize
interference rejection.
Noise reduction
The
processing power of the 32-bit DSP produces results you
can hear! 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
A 100-step
digital noise blanker reduces interference from
pulse-type noise sources such as engine ignition
systems.
Dualwatch function
Dualwatch allows you to receive two
signals in the same band simultaneously. For example,
you can listen to a DX station transmitting on 14.025MHz
while also listening to the pileup calling him on
14.030MHz.
High stability TCXO unit The
IC-7600 provides ±0.5ppm frequency stability using a
high stability temperature-compensate crystal oscillator
(0
to +50).
This high stability TCXO unit offers stable operation
even during continuous transmission on RTTY or PSK31
mode.
5.8 inch ultra-wide viewing angle TFT display
The IC-7600's
ultra-wide viewing angle display has excellent color
rendition and high contrast ratio with fast response
time. These features allow the spectrum scope and
simulated analog meters to move smoothly and naturally.
while LED backlighting offers faster start-up, stable
brightness, and very long life.
Spectrum scope
The dedicated
spectrum scope DSP with built-in digital filtering
greatly improves dynamic range, response time, and
frequency accuracy of the spectrum scope. The scope
automatically selects the optimum resolution band on the
sweep bandwidth. In addition, the spectrum scope range
can be set independently from the receiving frequency.
You can monitor band conditions
between the selected sweep edges (Max. 500kHz) in the
fixed mode, as well as sweep a selected band width
centered on the receiving frequency in the center mode.
Digital voice memory
With digital voice memory, you can
record the incoming signal and immediately replay the
audio, a must-have feature for DXing and contesting.
Because the transceiver is recording continuously,
time-sift playback can replay the15 seconds of audio
that you heard <before> you pushed the Rec button!
The IC-7600 has a 4 channel transmit memory (maximum 90
seconds per channel) and 20 cannel receive memory
(maximum 30 seconds per cannel, total 200 seconds with
20 channels). In addition, the recorded incoming signal
can be saved on a USB flash drive.
Multi-function meter
The
multi-function meter allows you to observe the
transmit/receive conditions at a glance.
In addition to the signal strength, transmit power
level, ALC, compression level and SWR meters the IC-7600
shows the drain terminal voltage of the final amplifier
(Vd), the drain current of the final amplifier (Id) and
temperature of the PA circuit (TEMP).
RF speech compressor
The digital RF
compressor boosts average RF output, improving signal
strength and readability.
RTTY /PSK31 operation with a USB keyboard
Simply plug in a
USB keyboard to operate RTTY and PSK! The digital
twin-peak filter greatly reduces interference and a
tuning indicator helps you zero-beat the signals. Eight
RTTY and PSK transmit memories store up to 62 characters
per channel.
Triple band stacking register
The triple band
stacking register quickly memorizes and calls up the
operating frequency and mode for 3 channels on each
band. Just push the band key button (ten-key pad), and
you can call up the last operating frequency and mode.
This function is convenient especially when switching
bands during contests, etc.
Programmable band edge beep
You can program the band edge not
only according to the amateur radio band plan but also
more specific frequencies like contest frequencies, CW
operating mode, etc.
If you try to
operate on the OFF band, the transceiver alerts you with
a beep sound. You can also inhibit transmitting in the
OFF band.
Built-in memory keyer
Built-in memory
keyer provides 4 channels for CW mode and8 channels each
for RTTY and PSK31 modes, capable of string up to 70
characters for each channels. The memory keyer is useful
for sending CQ or exchanging numbers during contests.
When not contesting, you can store and send your name,
QTH, rig, etc. With a USB keyboard, you can send memory
contents using a function key on the keyboard.
USB connectors on the front and rear panel
The IC-7600 has
one USB connector on the front panel and one on the rear
panel. you can connect a USB keyboard or USB flash drive
to the front panel (type A plug) and connect a PC to the
rear panel (type B plug). Using the CI-V data format and
external software*, you can control the IC-7600 from a
PC via the USB port. You can also transfer audio, both
transmit and receive, via the USB port.
*software is not supplied from Icom.
Microphone equalizer and adjustable transmit
bandwidth
The built-in
audio equalizer has separate bass and treble adjustments
for a total of 121 combinations, so you can adjust the
tonal quality of your voice as you want. In addition,
the transmit bandwidth is selectable from 100, 200, 300,
500Hz at the low-pass edge, and 2500, 2700, 2800, 2900Hz
at the high-pass edge, respectively.
Three types of high and low
combinations can be stored in the memory as favorite
settings. With this flexibility of DSP-based waveform
shaping, transmit audio quality is adjustable to your
preference.
High power final amplifiers
High-power
FET transistors, RD100HHF1, are used in the PA unit
providing excellent signal quality and low IMD
characteristics. With a large heat sink and cooling
fans, reliable 100W output at high duty cycle can be
used, for example in contesting or data modes.
Two types of send relay settings
For amplifier
keying (SEND jack), you can select either a mechanical
relay (max. 16V/500mA) or a FET switch (max.
250V/200mA). The FET switch is designed to key older
tube-type amplifiers that may have high voltage on the
SEND line.
Built-in high-speed automatic antenna tuner
The antenna
tuner memorizes its settings based on your transmit
frequency, so that it can rapidly tune when you change
bands. High-voltage capacitors allow
continuous-duty-cycle full-power operation.
