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
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
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
The 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
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. There filter memories allow you to change filter
settings instantly, a great help during contesting or other
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
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.
The 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
The IC-7600 provides ±0.5ppm frequency stability using a high
stability temperature-compensate crystal oscillator (0°C to +50°C)
This high stability during continuous transmission on RTTY or
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.
The 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 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-shhift playback can replay the 15 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 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
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 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
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 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 preference.
High 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 SEND line.
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 clarity.
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.
