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 IP3 in the HF bands without sacrificing receiver
sensitivity. Even a weak signal adjacent to strong signals is 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 DPS
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
IC-7600 has three built-in 1st IF 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
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. There filter memories allow you to change filter
settings instantly, a great help during contesting or other high-rate
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
processing power of the 32-bit DSP producers 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 contract or not.
A 100-step digital noise blanker reduces interference from pulse-type
noise sources such as engine ignition systems.
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
IC-7600 provides ±0.5ppm frequency stability using a high stability
temperature-compensate crystal oscillator (0°C to +50°C). This high
stability TXCO 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.
dedicated spectrum scope DSP with built-in digital filtering greatly
improves dynamic range, response team and frequency accuracy of the spectrum
scope. The scope automatically selects the optimum resolution based 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 bandwidth centered on the receiving frequency in the center
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-shhift playback can
replay the 15 seconds of audio that you heard you pushed the Rec
The IC-7600 has a 4-channel transmit memory (maximum 90 seconds per
channel) and 20 channel receive memory (maximum 30 seconds per channel,
total 200 seconds with 20 channels). In addition, the recorded incoming
signal can be saved on a USB flash drive.
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 power, 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
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
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
Built-in memory keyer provides 4 channels for CW mode and 8 channels each
for RTTY and PSK31 modes, capable of storing up to 70 characters for each
channel. 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 function
key on the keyboard.
USB connectors on the front and rear panel
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.

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 lowpass 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
power final amplifiers
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
Two types of send relay settings
The noise reduction separates the target signal from random noise
components. By using the excellent performance of the 32-bit floating point
DSP, this separation is made immediately without a delay and extracts
signals from noise components. The noise reduction suppression level is
variable in 16 steps to adjust the balance between the S/N ratio and
Built-in high-speed automatic antenna tuner
the antenna tuner memorizes its settings based on your transmit
