<strong>IC-7600 Review</strong> by VA7OJ : <strong>Download </strong>the fine User Evalutation &amp; Test Report (PDF format) <span style="color: #ff0000;">with the Link below or clik on the Banner  below</span> -<br />
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! &#8211; Many Thanks Adam, by www.radiocronache.com.</p>
<p style="text-align: justify;"><span style="color: #ff0000;">Clarification</span>: The test on pag. 8, par. 2) of this report is for Reciprocal Mixing Noise, not IMD dynamic range &#8211; <span style="color: #ff0000;">Precisazione</span>: 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.</p>
<p style="text-align: justify;">Questo eccellente rapporto, realizzato da VA7OJ/AB4OJ, Adam, descrive dettagliatamente  la valutazione del nuovo IC-7600 S/N #0201203 dal punto di vista dell&#8217;utente. Poi sull&#8217;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&#8217;IC-7600  nel suo shack, quindi ha avuto l&#8217;opportunità di usare la radio e valutarne le principali caratteristiche  compreso il comportamento in aria &#8211; Adam ha testato il livello di uscita RX Baseband dalla porta USB utilizzando DM780*, con  l&#8217;interfaccia di Ham Radio Deluxe (* <a href="http://www.ham-radio-deluxe.com/Downloads/tabid/54/Default.aspx">HRD by HB9DRV</a>),  l&#8217;IC-7600 ha mostrato subito nel computer l&#8217;indicazione &#8220;USB Audio Codec&#8221; e HRD ha cominciato a lavorare.</p>
<p style="text-align: justify;">Al par. 20) Conclusioni, di questa ampia relazione, Adam scrive: &#8220;&#8221;Dopo alcuni giorni trascorsi piacevolmente nella &#8220;cabina di pilotaggio&#8221; dell&#8217;IC-7600, sono molto favorevolmente impressionato dalla sua solida e raffinata struttura, dall&#8217;attraente e informativo display, dal facile approccio operativo molto intuitivo,  dall&#8217;impressionante serie di eccellenti funzioni e per le prestazioni in-aria. Questa radio offre la maggior parte delle funzionalità e delle prestazioni dell&#8217;IC-7700 però con le dimensioni simili ad un Pro3. L&#8217;apparato si pone in una classe di prezzo  che è tra il Pro3 e l&#8217;IC-7700. Icom com un suo colpo vincente ha abilmente introdotto una  nuova interfaccia USB per il computer&#8221;" -</p>
<p style="text-align: justify;">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 &#8220;PCM baseband&#8221;  tra il computer e l&#8217;IC-7600. [<span style="color: #ff0000;">Nota</span>]: Icom Inc. ha già rilasciato il software  USB Drive Vers.1.00, da installare nel computer. <em>Vedi sotto il Link</em><br />

<p><strong>EN:</strong> 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&#8217;s principal features and evaluate its on-air behavior &#8211; Adam thested the RX baseband output levels at the USB port using DM780*, interfacing with Ham Radio Deluxe (<a href="http://www.ham-radio-deluxe.com/Downloads/tabid/54/Default.aspx">*HRD by HB9DRV</a>), the IC-7600 showed up in the computer as &#8220;USB Audio Codec&#8221;, HRD started working</p>
<p style="text-align: justify;"><img class="alignleft size-thumbnail wp-image-1259" title="VA7OJ's-shack" src="http://www.radiocronache.com/wp-content/uploads/2009/04/va7ojs-shack-150x137.jpg" alt="va7oj's-shack" width="150" height="137" />On this report, par. 20) Conclusion, Adam writes: &#8220;&#8221;After several days&#8217; worth of &#8220;cockpit time&#8221; on the IC-7600, Adam .. very favorably impressed by its solid, refined construction, attractive and informative display, easy familiarization experience, smooth operating &#8220;feel&#8221;, 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&#8221;"  -<br />
Indeed the USB port trasports non only CI-V data, but also TX and RX PCM baseband between the IC-7600 and the computer. [<span style="color: #ff0000;">Note</span>] Icom Inc.

<strong>The IC-7200</strong> is equipped with a rear-panel USB &#8220;B&#8221; port for CI-V controll and PCM baseband (audio) imput/output. <br />
Questa nuova e interessante caratteristica penso che <strong>sarà</strong> applicata  su tutti i futuri Transceiver HF Icom;</p>
<p style="text-align: justify;">The TX Block diagram, riportato sull&#8217;immagine (<span style="color: #ff0000;">clik for larger image</span>), illustra il percorso del segnale audio dall&#8217;USB interface (USB2502) controllata dalla CPU (MC16C/62P) verso la USB Codec (PCM2901E) poi all&#8217; Amp. TS462CPT, quindi al Codec/Mixer di 3rd IF (AK4620BVFP) in cui confluisce in alternativa al segnale MIC tramite l&#8217;elaborazione del DSP. </p>
<p style="text-align: justify;">L&#8217;IC-7200 è dotato di una porta USB &#8220;B&#8221; sul pannello posteriore. Così, la radio può essere collegato direttamente ad un computer portatile o ad altri PC tramite un cavo USB &#8220;A-B&#8221;.   La porta USB trasporta non solo i dati CI-V, ma anche la banda base PCM per TX e RX tra IC-7200 e il computer. Di conseguenza, il cavo USB è l&#8217;unica connessione richiesta tra Radio e PC. Senza l&#8217;eterno disordine dei cavi e scatole o interfacce convertitori di livello!<br />
Si deve istallare il driver USB &#8211; scaricabile dal sito assistenza globale della Icom Giappone, inoltre è anche necessario installare un altro software di gestione, come l&#8217;eccellente HRD &#8211; Ham Radio Deluxe. (regolate correttamente i livelli di imput di HRD in base al segnale PCM banda base della porta USB)</p>

<p style="text-align: justify;"><a href="http://www.ab4oj.com/icom/ic7200/7200notes.pdf"></a><span style="color: #ff0000;"><a href="http://www.ab4oj.com/icom/ic7200/7200notes.pdf"><img class="alignleft size-full wp-image-714" title="user-evaluation-hp1" src="http://www.radiocronache.com/wp-content/uploads/2008/12/user-evaluation-hp1.jpg" alt="" width="360" height="189" /></a>Test re-run with new HP Spectrum Analyzer by Adam VA7OJ &#8211; <strong>Rev. 2, Nov. 28, 2008</strong><br />
</span><strong>IC-7200</strong> User Evaluation and Test Report, 17 pages; This report, by Adam Farson VA7OJ, describes the evaluation of IC-7200 S/N 0201013 from a user perspective, as well as the results of several RF lab test performed on the radio. Adam spend a number of days with the IC-7200 in your ham-shack.  <span style="color: #ff0000;"><strong>Clik</strong> to image for download the Adam&#8217;s very nice report (.pdf formt)<br />
</span></p>
<p><strong>ENG:</strong> <em>The IC-7200 is equipped with a rear-panel USB B port. Thus, the radio can be directly connected to a laptop or other PC via a standard USB A-B cable. The USB port trasports not only CI_V data, but also TX and RX PCM baseband between the IC-7200 and the computer. As a result, the USB cable is the only radio/PC connection required. Gone forever is the mess of cables, levl converters and interface boxes!<br />
I istalled the Icom USB drivers &#8211; downloadable from the Icom Japan world-wide support site and other software come HRD, Ham Radio Deluxe. (set the PCM baseband level correctly at the imput to HRD software).</em></p>

La sintonia del <strong>Perseus </strong>sincronizzata con altri Transceivers muniti di <strong>CAT</strong> è ora possibile; Infatti l&#8217;interfaccia di Perseus con altri RTX, è consentita dall&#8217;ultima versione del suo software che, con CAT system, CI-V e Virtual Port, con la sincronizzazione di Ham Radio Deluxe internamente al Computer, permette di mettere inpasso le sintonie di PERSEUS e di alri RTX supportati dal noto software di Simon: <strong>HRD</strong>.</div>
<p><strong>Switch BOX</strong>: la prossima disponibilità dell&#8217;unità di commutazione esterna del collegamento d&#8217;antenna tra il ricevitore SDR ed un RTX separato renderà possibile usare Perseus in modo atuomatico e trasmettere con il proprio RTX analogico e ricevere con il digitale, usufruendo di tutte le relative funzioni di filtraggio e di visione panoramica dello spettro. La sintonia sincronizzata di entrambi gli apparati, come sopra, potrà essere comandata sia con la &#8220;manopola&#8221; del Main Tuning del Transceiver sia dal software del Perseus.<br />

<div>
<div>
<p style="text-align: justify;">C&#8217;è stato un primo interesse, suscitato dalla FlexRadio System USA con il Flex-5000A, che è un Transceiver (<strong>rtx</strong> 100W) con architettura SDR (la stessa del vecchio SDR1000) cioè con l&#8217;ADC preceduto da un QSD che in quadratura converte i segnali RF a 9kHz (variabile fino a 20) da cui risultano poi i due segnali I/Q per il convertitore A/D a 24bit da avviace al Computer, però questa volta senza usare l&#8217;imput della Sand-Card;</p>
<p>Da fine 2007 è arrivato un nuovo prodotto tutto italiano: Microtelecom Srl di Udine, ha lanciato ilsuo <strong>Perseus</strong> un eccellente Ricevitore SDR di nuova generazione, a campionamento diretto a 80MS/s, interfaccia USB 2.0, valore i IP3 imput a +30dBm. Il software aggiornato di Perseus supporta la visualizzazione e registrazione da 200kHz a 800kHz di larghezza di banda, con reiezione di immagine di 100dB.<br />
La realizzazione di <strong>Nico Palermo</strong> è completata on board con un ottimo front-end analogico con attenuatore da 0 a 30dB, un banco di filtri di preselezione passa banda e di un pre-amp ad alta dinamica, è fornito con un apposito software per Windows (anche Vista) con ottima grafica. Si può dire che Perseus risulta essere un ottimo progetto con ingegnerizzazione già consolidata e con un buon riscontro sul mercato anche internazionale, che risulta in forte espansione.<br />

Le novità non finoscono qui, la competizione tecnologica si arricchisce ora con l&#8217;arrivo del <strong>QS1R</strong> QuickSilver,  un SDR progettato da Phil Covington, N8VB, che<strong> </strong>si basa su approccio molto simile a quello del Perseus, con la conversione ADC in antenna. Qui si usa lo stesso LTC2208, <span style="color: #cc0000;">però</span> a 125MS/s con 16bit, della Linear Technologies, una nuova ed efficiente FPGA HDL Altera Cyclone III EP3C16; La banda di ricezione: BNC LPF imput 15kHz to 55MHz; Dispone di un SMA direct imput 15kHz to 300MHz, con possibilità di integrare espansioni di funzioni; Rilevante è il fatto che, date le specifiche di progetto ADC e FPGA e con il Software (open source GPL3) SDRMAX-II oltre al controllo, filtraggio e demodulazione il QS1R supporta la visualizzazione e registrazione su HD di una larghezza di banda selezionabile da 50kHz<strong> </strong>fino a 50MHz.<br />

<p style="text-align: justify;"><span style="color: #cc0000;">Sul sito QS1R sono riportate le specifiche (Standard VERB) del progetto QS1R:</span> Clipping RF Level: +9 dBm (~S9+80db); Max Display Bandwidth: 4MHz; I/Q Image Rejection: +90 dB; MDS (500 Hz): -122 dBm @ 14MHz; BDR: 125 dB; <strong>Novità</strong> del 15.04.2008: è stata implementata l&#8217;interfaccia Dll ed ora si può usare anche il software (IT) WinRad di I2PHD e si dice che anche l&#8217;HRD di Simon. Sono prevsite a breve aggiunte<strong>:</strong> un Bandpass and RF Amp-Attenuator board, di un QS1T DUC Trasmitter Add-on board e altre Planned Add.<br />
