    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)

    Dynamic range characteristicsIcom'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

    Inband dynamic range characteristics Compared to the IC-756PROIIIThe 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.
