Dual DSP for transmit/receive and spectrum scope
The IC-7600 is powered by two 32-bit floating point DSP units for Transmit/Receive and spectrum scope. TheDSP units provide high performance comparable to our top-of-the-line transceivers IC-7800 and IC-7700. Andthe IC-7600 achieves similar performance for high speed digital signal processing combined with our analog RF technologies.
104dB dynamic range and +30dBm third order intercept point (IP3)
Icom’s long years of analog RF circuit experience combined with the latestdigital technology results in an astonishing 104dB receiver dynamicrange and +30dBm IP3 in the HF bands without sacrificing to the receiversensitivity. Even a weak signal adjacent to strong signals is received bythe IC-7600.
Double conversion superheterodyne dramatically improves inband IMD
As you may have seen in the IC-7800 or IC-7700, the IC-7600 employs adouble conversion superheterodyne system which has an image rejectionmixer for the 2nd mixer stage. When compared to the triple conversionsystem, the double conversion system is technically difficult to achieve astable mixer operation but it dramatically reduces signal distortion throughIF processing and provides a high-fidelity signal to the DSP unit. As aresult, the IC-7600 will provide a clearer, more distinct signal.
The AGC loop management controlled by the DSP unit
The IC-7600 detects the AGC voltage from the signal which has passed the digital IF filter. That means the IC-7600 prevents the AGC blocking from a nearby strong signal to bring out the full potential of the digital IF filter.The digital IF filter and manual notch filter are also processed in the AGC loop.
Three 1st IF filters, including 3kHz bandwidth.
The IC-7600 has three 1st IF filters (roofing filters) in front of the 1st IF amplifier stage. You can select an appropriate filter width from 3kHz, 6kHz and 15kHz filter depending on operating mode. (15kHz fixed forFM mode). Especially the 3kHz 1st IF filter protects the subsequent stage from the influence of the nearby strong stations.
Digital IF filter.
The IC-7600 also incorporates the “build yourown” filter feature. This allows the operator toadjust filter shaping (sharp or soft), filter bandwidth,and center frequency characteristics,without missing the action. Multiple filter memoriesstore the last used filter settings by usedoperation mode. This allows the operator toquickly switch filters for constant operating conditions,such as in a contest.
Digital twin PBT.
Once the IF filters have been “tweaked”, the operator has additional control with the digital twin Passband Tuning(PBT). The digital twin PBT allows flexibility of the IF shift and narrowing of the digital IF passband in moving theIF passband. With the digital IF filters, PBT performance allows you to cut away all the interference and noiseto hear the actual signal.
Digital manual notch filter.
Signals such as heterodynes and AM carriers can be eliminated withautomatic notch filter technology, making interference from RF sourcessuch as beat signals and RTTY signals a thing of the past. Additionally,the filter shape of the manual notch can be adjusted in three shapes,with more than 70dB attenuation.
Noise reduction
The 32-bit DSP processing power produces real results by separating asignal component from the noise with the 16-step variable noise reduction.By suppressing the noise components, an outstanding signal-tonoiseratio is achieved, providing clear, clean audio in all modes withoutdistortion of the target signal.
Noise blanker
The noise blanker reduces pulse noise such as engine ignition, with the fully adjustable 100 steps noise blanker.Dualwatch functionThe dualwatch function allows you to receivetwo signals on the same band simultaneously.The main and sub-receivers can be toggledeasily as the main and sub-receivers have identicalcomponents.
High stability TCXO unit.
The IC-7600 provides ±0.5ppm frequency stability using a high stabilitytemperature compensate crystal oscillator (0°C to +50°C). This high stabilityTCXO unit offers stable operation even during RTTY mode or PSK31 mode operation.
5.8 inch ultra-wide viewing angle TFT display
The IC-7600's display realizes ultra-wide viewing angle providing excellentcolor gradation reproducibility and a high contrast ratio at virtuallyany viewing angle. It improves the readability of the screen, regardlessof installation position. In addition, as the response time is almost constantat all color gradations, the display provides smooth and naturalmovement in the spectrum scope. The white LED backlighting offersfaster start-up time, stable brightness and relatively longer lifetime.
Spectrum scope.
The DSP unit dedicated for the spectrum scope greatlyimproves dynamic range, response time and frequencyaccuracy of the spectrum scope. The spectrum scope ofthe IC-7600 also uses the digital IF filter incorporated withthe DSP unit. The optimum resolution bandwidth is automaticallyselected according to the sweep band width. Inaddition, the spectrum scope range can be set independentlyfrom the receiving frequency. You can monitorband conditions between the selected sweep edges (Max. 500kHz) in the fixed mode, as well as sweep a selectedband width centered on the receiving frequency in the center mode.
Digital voice memory.
The digital voice memory which allows you to record incoming signal and replay the audio is now the must-haveitem for DX hunting and contesting. The IC-7600 has dedicated “Rec” and “Play” buttons on the front panel forimmediate access. The time-shift playback function allows you to start saving the incoming signal from theimmediate preceding 15 seconds before pushing the button. It is useful for checking a call back.The IC-7600 has a 4 channel transmit memory (max 90 seconds per channel) and 20 channel receive memory(Max 30 seconds per channel, total 200 seconds with 20 channels). In addition, the recorded incoming signalcan be saved on a USB flash drive.
Multi-function meter
The multi-function meter allows you to grasp the transmit/receive conditionsat a glance.In addition to the signal strength, transmit power level, ALC, compressionlevel and SWR meters, the IC-7600 shows the drain terminal voltageof the final amplifier (Vd), the drain current of the final amplifier (Id)and temperature of PA circuit (TEMP).
RTTY/PSK31 operation with a USB keyboard
Simply by plugging in a USB keyboard, the IC-7600allows you to start transmitting RTTY and PSK31 modesas well as receiving. The digital twin peak filter reducesinterference from other signals between the receivingtones. The tuning indicator helps you to zero in on a signal.In addition, a total of 8 channels of RTTY and PSKtransmit memory stores up to 62 characters of often usedmessages for each channel.
RF speech compressor.
