I could not find any fault with the Transceiver IC-7600.  This radio promises to be a worthy replacement for the tried and proven IC-756Pro3! – Many Thanks Adam, by www.radiocronache.com.

Clarification: The test on pag. 8, par. 2) of this report is for Reciprocal Mixing Noise, not IMD dynamic range – Precisazione: La prova a pag. 8, par.2) della  relazione riguarda la reciproca miscelazione con il rumore di fase del LO, non sono valori della gamma dinamica IMD.

Questo eccellente rapporto, realizzato da VA7OJ/AB4OJ, Adam, descrive dettagliatamente  la valutazione del nuovo IC-7600 S/N #0201203 dal punto di vista dell’utente. Poi sull’Appendice 1) vengono riportati, con molti dettagli tecnici, misure strumentali e diagrammi, molti risultati dei test principali eseguiti sul transceiver nel proprio laboratorio RF. Adam ha potuto utilizzare, per un certo numero di giorni, l’IC-7600  nel suo shack, quindi ha avuto l’opportunità di usare la radio e valutarne le principali caratteristiche  compreso il comportamento in aria – Adam ha testato il livello di uscita RX Baseband dalla porta USB utilizzando DM780*, con  l’interfaccia di Ham Radio Deluxe (* HRD by HB9DRV),  l’IC-7600 ha mostrato subito nel computer l’indicazione “USB Audio Codec” e HRD ha cominciato a lavorare.

Al par. 20) Conclusioni, di questa ampia relazione, Adam scrive: “”Dopo alcuni giorni trascorsi piacevolmente nella “cabina di pilotaggio” dell’IC-7600, sono molto favorevolmente impressionato dalla sua solida e raffinata struttura, dall’attraente e informativo display, dal facile approccio operativo molto intuitivo,  dall’impressionante serie di eccellenti funzioni e per le prestazioni in-aria. Questa radio offre la maggior parte delle funzionalità e delle prestazioni dell’IC-7700 però con le dimensioni simili ad un Pro3. L’apparato si pone in una classe di prezzo  che è tra il Pro3 e l’IC-7700. Icom com un suo colpo vincente ha abilmente introdotto una  nuova interfaccia USB per il computer”" -

In effetti la porta USB è innovativa, non trasporta solo i dati  standard CI-V, ma comprende anche i segnali  audio TX e RX in “PCM baseband”  tra il computer e l’IC-7600. [Nota]: Icom Inc. ha già rilasciato il software  USB Drive Vers.1.00, da installare nel computer. Vedi sotto il Link

EN: This fine report, by VA7OJ, Adam describes the evaluation of the new IC-7600 S/N #0201203 from a user perspective.  Appendix 1 presents results of RF lab test suite performed on the radio, detailed measurements and diagrams. Adam was able to spend a number of days with the IC-7600 in your ham-shack, and thus had the opportunity to exercise the radio’s principal features and evaluate its on-air behavior – Adam thested the RX baseband output levels at the USB port using DM780*, interfacing with Ham Radio Deluxe (*HRD by HB9DRV), the IC-7600 showed up in the computer as “USB Audio Codec”, HRD started working

On this report, par. 20) Conclusion, Adam writes: “”After several days’ worth of “cockpit time” on the IC-7600, Adam .. very favorably impressed by its solid, refined construction, attractive and informative display, easy familiarization experience, smooth operating “feel”, impressive array of features and excellent on-air performance. This radio offers most of the functionality and performance of the IC-7700 in a Pro3-size package, and in a price class between the Pro3 and the IC-7700. Icom have again scored a coup with the straightforward USB computer interface”"  -
Indeed the USB port trasports non only CI-V data, but also TX and RX PCM baseband between the IC-7600 and the computer. [Note] Icom Inc. Software USB Drive Vers.1.00 is necessary. Free download Vers.1.00  and read the manual  from Icom Inc. official  web

[Note - radiocronache.com®]
The roofing filter and the Ceramic Filter is not a ultimate selectivity on the this tranceiver. The designer uses the DSP process to define the selectivity of the receiver for each supported emission type. The purpose of the 6kHz roofing  filter reduces the statistical likelihood that strong undesired signals well outside BPFs, to suppress images produced in the first mixer. The Ceramic Filter on the 2nd IF 455kHz to suppress images produced in the 2nd IF mixer will enter the IF chain and over-range the ADC Codec. As long as  the ADC is operating in its linear range, the DSP IF filter will do its job.
———————————————————————————————
Design and architecture:

The RX signals are passed through one of 9 BPFs on the RF UNIT.  The BPF for 50 MHz band contains a separate Pre-amp to make up the loss for high sensitivity on this band. While the Main Pre-amp function is activated, the RX signals from the BPF are applied to the noiseless feedback AMP 2SC5551F. This Pre-amp provides low-noise, high RF gain and good IP characteristic. The amplified or not RX signals are entered to the MAIN UNIT, then applied on the 1st mixer 2SK1740 x4 junction FETs. A quad-structured 1st mixer circuit, provides high enough intercept point. RX signals are mixed with the 1st LO signals from the 1st LO AMP 2SC3357 to be converted into the 64.455 MHz 1st IF signal. The 1st IF signal is filtered by the 6kHz Roofing Filter (FI541 – FL421) to remove the RX frequency signal and 1st LO signals, and amplified by the 1st IF AMP 3SK264. The amplified 1st IF signal is applied to the 2nd duble balanced mixer HSB88WS to converted into the 455 kHz 2nd IF signal.
The 2nd IF signal is filtered by Ceramic Filter CFWS455HT (FI601) and amplified by 3SK264 x2 IF AMP and 2SC4081 BUFF, then applied to the 3rd mixer TS5A2053. – The converted 15.625 kHz 3rd IF signal are entered to the ADSP-BF532SBSTZ400 on the DSP section, passed through the (ADC/DAC) Codec AK4620B. – Digital IF DSP for: Twin PBT, Noise Reduction, Manual Notch, Automatic Notch, NB etc. –[radiocronache.com®]

IC-7600 the flagship’s linage. Employ 1st IF analog mixers, 2nd IF rejection mixer (SDR -I/Q mixer type) and digital signal processing DSP.  It is most interesting that the new Transceiver Rohde & Schwarz® 4100 HF radio family also employs this architectur. (Report/image  www.radiocronache®)

IT: IC-7600 ha lo stesso circuito del IC-7800 e IC-7700 non avendo più lo statio IF a 455kHz e quindi un terzo mixer come il Pro3. Questo evita sia il rischio di altri seganli spuri che l’ulteriore fase di rumore del mixer, fattori di distorsione e di intermodulazione.
IC-7600, utilizza un sistema a doppia conversione superheterodina, con l’impiego di un mixer a reiezione d’immagine (tipo SDR I/Q  mixer) nello stadio della 2nd IF che migliora la “imband IMD”.  Il sistema a doppia conversione  necessita  di maggior tecnologia però si riduce notevolmente la distorsione del segnale e la relativa elaborazione a media frequenza con il risultato di ottenere un segnale di miglior fedeltà all’ingresso del codec A/D e quindi all’unità di elaborazione digitale DSP Unit. TMS320C6726BRFP – 266MHz clock – 32bit floating point – Capacity = 1600MFLOPS
[Note] Nel cosidetto I/Q Mixer il segnale di 1st IF viene splittato in due segnali di uguale frequenza per essere amplificati da due IF AMPs e poi inviati al 2nd mixer a reiezione di immagine. Le due componenti di questo segnale RX IF, come si vede  dallo schema a blocchi, vengono miscelati con due segnali alla stessa frequenza attraverso lo split e sfasamento dell’OL di 90 gradi. I segnali IF sfasati di 90 gradi I (In fase) Q (Quadratura) così ottenuti vengono ricomposti da un rifasatore e poi elaborati digitalmente, attraverdo il convertitore A/D, dal DSP Unit, che per il progetto richiede ottime conoscenze tecniche ed un elevato sviluppo del software residente nel circuito del DSP Unit, nello stesso Transceiver che è complessivamente gestito dal software dal Main CPU.

È molto interessante il fatto che la nuova serie di radio HF 4100 della Rohde & Schwarz® impiega una simile architettura. Infatti il Transceiver R&S® M3SR Serie 4100, utilizza un sistema a doppia conversione superheterodina e combina l’ottima gamma dinamica di una radio con ottimo mixer analogico e dall’ultimo sistema di processo ed elaborazione digitale del segnale IF e del segnale audio. La frequenza della 2nd IF a 48 kHz è campionata, digitalizzata ed elaborata utilizzando i processori di segnali digitali DSP (nell’IC-7600 la 2nd IF è 36 kHz mentre sull’ IC-R9500 è proprio a 48 kHz).
L’IC-7600 ha anche un doppio loop AGC, uno analogico ed uno digitale entrambi controllati dal cuore del circuito IF DSP. Il segnale necessario all’AGC viene prelevato dopo il filtro digitale, così si previene l’eventuale bloccaggio dell’AGC dovuto a dei forti segnali adiacenti (“pumping” the AGC). Da notare che tanto il filtro digitale IF (Twin PBT, IF Shifth, Twin Peak ecc.) che il filtro notch (NOTCH, NR, NB ecc) vengono elaborati digitalmente nel DSP e sotto controllo dei loops dell’AGC.

ENG: IC-7600 the flagship’s linage, eliminate the 455 kHz IF stage and third mixer, with their attendant risks of spurs, additional phase noise and IMD degrade. IC-7600 employs a double conversion superheterodyne system, which has an image rejection mixer (SDR I/Q mixer type) for the 2nd mixer stage improve inband IMD.
[Note] SDR I/Q mixer: The filtered 1st RX IF signal is amplified by two 1st IF AMPs, then splitted into two before being applied to the 2nd mixe, as a image rejection. Each divided signal RX IF signal is mixed with 2nd LO signals to be converted into the 36 kHz 2nd RX IF. One of the LO signal is 90 degrees phase shifted before being applied to the 2nd mixer, and the converted 2nd mixer IF is 90 degrees phase shifted too. – I (Inphase) Q (Quadrature) signals are buffer and amplified by 2nd IF AMP. Then the 2nd RX IF signals whose phase shifter, then composed by the composer.The composed RX IF signal is amplified, then entered by the A/D converter to the DSP Unit. – TMS320C6726BRFP, 266MHz clock , 1600MFLOPS!
It is most interesting that the new Transceiver Rohde & Schwarz® 4100 HF radio family also employs this architecture. The R&S® M3SR Series 4100 employs a double conversion superheterodyne system, combines the unmatched dynamic range of radios with analog mixers with the latest in digital IF and audio signal processing. The second IF frequency of 48 kHz is sampled (IC-7600 has 2nd IF 36 kHz, IC-R-9500 has 48 kHz), digitized and processed using DSP digital signal  processors.

Built-in a high-quality DSP-based Baudot RTTY modulator /demodulator and direct PC keyboard connection capability for RTTY and PSK operations without a PC. RTTY operation can be performed without an external RTTY terminal, TNC or PC. Pre-set characters can be sent using the RTTY memory. The contents of the RTTY memory/received signal can be saved into the USB-Memory. Two data formats, Text and HTML, are available for PC data storage.
Built-in a high-quality DSP-based PSK encoder /decoder is built-in to the IC-7600. When connecting a PC keyboard, BPSK (Binary Phase Shift Keying) and QPSK (Quadrature Phase Shift Keying) modes are available for PSK. The transmission contents can be typed before being transmitted. The contents of the PSK memory/received signal canbe saved into the USB-Memory.
[Note]: When a PC keyboard is connected to [USB] connector on the front panel, the RTTY/PSK/CW memory contentst nad the file name can also be edited from the keyboard. In this case, a USB hub is required.

Twin PBT® operation: in SSB/CW/RTTY/PSK/AM the PBT (Passband Tuning) electronically narrows the IF passband width by shifting the IF frequency slightly outside of the IF filter passband to reject interference. The IC-7600 uses DSP for the PBT function. Moving both [TWIN-PBT] controls to the same position shifts the IF both above and below the received frequency.
DSP filter shape (Soft/Sharp): The type of DSP filter shape for each SSB, SSBD (data) and CW can be selected independently from soft and sharp. IC-7600 DSP use the TMS320C6726BRFP at 266MHz.
Roofing filter selection: The IC-7600 has 3, 6 and 15 kHz roofing filters at the 1st IF frequency. The roofing filter provides interference reduction from nearby strong signals.

Large LCD with LED backlight multi-function Display. High resolution spectrum scope screen, several times to select the scope span: ±2.5, ±5.0, ±10, ±25, ±50, ±100 and ±250 kHz are available. This DSP-based spectrum scope allows you to display the frequency and relative signal strength  of received signals on the strengths of signals. The IC- 7600 has two modes for the spectrum display – one is center mode, and the other is fixed mode. In addition, the IC-7600 has a mini scope screen to save screen space.

Dualwatch operation. Dualwatch monitors 2 frequencies with the same mode simultaneously. During dualwatch, both frequencies should be on the same band, because the bandpass filter in the RF circuit is selected for the main readout frequency.

Push [MAIN/SUB] to enables the sub band access when changing the frequency to Main dial, etc. in sub band.
Adjust the [BAL] control to set a suitable audio signal strength balance between the main and sub readout frequencies. S-meter shows the combined signal strength. The dualwatch function is convenient for tuning the transmit frequency while monitoring both frequencies used for transmitting and receiving. Split frequency operation allows you to transmit and receive in the same mode on two different frequencies, on the main and sub readouts.

USB Rear connector. [USB] (Universal Serial Bus – B type) Connect a USB cable to be used for the modulation input, the transceiver operation with PC, the received audio and the decoded character import to the PC. Icom HP (http://www.icom.co.jp/world/support/index.html) gives the USB driver and the installation guide download service.

IC-7700: Icom Japan have released the latest firmware V1.04 on Dec 11, 2008

IC-7700 New Firmware Update – Icom Japan have released the latest firmware V1.04 on Dec 11, 2008.

Un nuovo Firmware Ver. 1.04 per l’IC-7700 è stato rilasciato dalla Icom Japan Global Support  ieri 11 Dicembre 2008.

————————————————————
La Icom dichiara che qusta nuova release apporta miglioramenti nel software che gestisce le performance nel DSP-Unit.  Le prime impressioni fanno osservare un miglioramento molto fine nel funzionamento [ NR] che ora sembra tracciare i picchi in modo un po ‘più veloce e attenuare un po’ meno i toni alti rispetto all  ver. 1.03 – Altra segnalazione riguarda  migliore comprensione durante la ricezione di BCC -SW in AM ascoltati in modo SSB/ECSS per rilevare segnali DX deboli, ora meno soggetti a distorsione da Qrn.

ENG:  Major points of update from Ver.1.03 to Ver.1.04: Improvements in the software performance for the DSP UNIT
Noted a very subtle improvement in [NR] operation. The NR seems to track voice peaks a little faster and attenuate highs somewhat less than in ver. 1.03.
Noted now listen to AM BBC WS on SSB/ECSS during the day during non DX time and hear it without the previous annoying distortion, as the audio no created loud transients of high notes. – - -  (Credit: Icom.co.jp/world/ Support)
