IC-7700 New Firmware Update - Icom Japan have released the latest firmware V1.04 on Dec 11, 2008.</p>
<p style="text-align: justify;">Un nuovo Firmware Ver. 1.04 per l&#8217;IC-7700 è stato rilasciato dalla Icom Japan Global Support  ieri 11 Dicembre 2008.</p>
<p style="text-align: justify;">&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;<br />
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 &#8216;più veloce e attenuare un po&#8217; 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. </p>

The final PA stage from IC-7700 delivers 200W.  Lo stadio finale di potenza realizzato da Icom per il transceiver IC-7700 eroga 200W (at full duty cycle) con un circuito push-pull di due MRF150 Power Field-Effect Transistor, prodotti dalla &#8220;tyco/Electronics - M/A-COM&#8221; ed alimentati con 48V DC.<br />
Transistor progettati per stadi di uscita linerai di potenza con frequenza fino a 150MHz. Specifiche da M/A-COM Technical Data  a 50 Volts, 30MHz, per ciascun MRF150: Output power = 150 Watts; Power Gain 17 dB (Typ); IMD (d3) (150W PEP) -32 dB (Typ); IMD (d11) -60 dB (Typ); <span style="color: #ff0000;">100% Tested </span>for load Mismatch at all Phase angles with 30:1 VSWR!<br />
Con il Link qui sotto si potrà leggere le regole di buon senso per una lunga vita delllo stadio finale di potenza. Regole che valgono per tutti gli apparati con PA a transistor! I consigli di Adam VA7OJ&#8217;s sono ben descritti nella sua pagina web appositamente dedicata, che si può scaricare con il Link qui sotto.<br />

<p style="text-align: justify;"><strong>ENG:</strong> <em>Download and read my friend Adam VA7OJ&#8217;s article &#8220;Common-Sense Rules for Long PA Life&#8221;  (Link up)<br />
The final PA stage delivers 200W (at full duty cycle) with a push-pull circuit using two MRF150 MOSFET RF power devices from tyco/Electronics M/A-COM, fed with 48V DC. The circuit is well-designed. The MRF150 designed primarily for linear large-signal output stages up to 150MHz frequency range.</em></p>

IC-7700 RF UNIT, 2nd Mixer as a image rejection, Circuit Description. <span style="color: #ff0000;">Note</span> the large toroidal coils, BPF bank<br />
Il segnale convertito di 1st IF viene poi filtrato da uno dei tre Roofing Filters (3-6-15 kHz). Il segnale di 1st IF filtrato viene suddiviso in due prima di essere applicato al 2nd Mixer che è un Mixer ad alta rejezzione d&#8217;immagine IF.<br />
Ciascuno dei due segnali splittati dalla 1s IF vengono mixati con i segnali del 2nd OL provenienti dal PLL UNIT, per essere convertiti nella 2nd IF a 36kHz. Uno dei segnali di OL  è spostato in fase di 90 gradi prima di essere applicato al 2nd Mixer (un <span style="color: #ff0000;">9A41-G</span>), e così anche uno dei segnali convertiti di  2nd IF risulta con fase diversa di 90 gradi rispetto all&#8217;altro.<br />
Questi due segnali convertiti di 2nd IF, sfasati tra loro di 90 gradi, sono ricombinati per la differenza di fase da un  sommatore (<span style="color: #ff0000;">NJM074M</span>) per ottenere così un unico segnale lasciando fuori gli altri segnali non coincidenti. Il segnale di 2nd IF ricombinato viene  fatto entrare nell&#8217;ADC (<span style="color: #ff0000;">AK5394</span>) per essere convertito a 24-bit in dati seriali. I dati seriali (digitali) sono applicati al DSP (<span style="color: #ff0000;">TMS320C6727</span>), sulla MAIN UNIT.</p>

<strong><br />
ENG:</strong> <em>The converted 1st RX IF signal is then filtered bay one of 1st IF Roofing Filters (3-6-15 kHz).<br />
The filtered 1st IF signal is splitted into two before being applied to the 2nd Mixers, as a image rejection Mixer. Each divided 1st IF signal is mixed with 2nd LO signals from the PLL UNIT, to be converted into the 36kHz 2nd RX IF signal. One of the LO signal is 90 degrees phase-shifted before being applied to 2nd Mixer (9A41-G), and the converted 2nd RX IF is 90 degrees phase-shifted too.<br />
These converted 2nd IF signals whose phase is different each other are phase-shifted by the phase shifter, then composed by the composer (NJM074M). The composed 2nd IF signal is amplified by another 2nd IF AMP, then entered to the ADC (AK5394) to be converted into the 24-bit serial data. The serial data is applied to the DSP (TMS320C6727) on the MAIN UNIT</em>.</p>

Truth of Icom HF Transceiver IC-781 to IC-7600. Special Movie from Icom: La verità sui noti Transceiver HF della Icom dotati di Monitor multifunzione, lo sviluppo della tecnologia DSP dedicata allo  Spectrum-Scope che è diventato un vero strumento di misura con BW e Span variabile, rispetto al primo innovativo IC-781 dotato di Monitor CRT con dati i immagini interessanti.<br />
L&#8217;evoluzione delle performance con speciali circuiti sviluppati da Icom come: validi D-MOS FET Quad-Mixer in 1st IF, preceduti dal Preselettore (DIGI-SEL) e dal BPF con bobine su toroidi e relè di commutazione. Impiego di Roofing Filter Hi-Spec e utilizzo di un Mixer I/Q nella 2st IF per elevare sia la Reiezione di immagine che la Reiezione di segnali forti adiacenti con migliore IP3 e IMD.  Sviluppo della tecnologia digitale  con IF DSP ora di 4^ geneerazione a 32bit e AD/DA a 24bit ad alta velocità di elaborazione per la riduzione del rumore e delle interferenze, sia con Notch da 70dB regolabile anche in larghezza, sia con il TWIN PBT (Doppio Pass Band Tuning) gestito dal DSP che controlla tutto il circuito AGC.<br />
Il Video mostra questa storia dal 1988 ad oggi:  IC-7600 Available end 2008, IC-7200 (2008), IC-7700 (2007), IC-7800 (2003), IC-756Pro Serie (1999), IC-756 (1996), IC-781/780 (1988); &gt; Distortion, Sensitivity, Selectivity, Stability, IP3 and more tecnicals news;</p>

			<content:encoded><![CDATA[<p style="text-align: justify;"><a href="http://www.radiocronache.com/wp-content/uploads/2008/08/shack-g6pz-a.jpg"><img class="alignnone size-medium wp-image-293" title="shack-g6pz" src="http://www.radiocronache.com/wp-content/uploads/2008/08/shack-g6pz-a-300x200.jpg" alt="" width="300" height="200" /></a><br />
IC-7700 PA failure?  Sono stati letti, con disappunto perchè questo non fa mai piacere, diversi post (es. I5IHE, I1xx/Dae, VK5EME, DL7USA, LA5EKA, HBxxx, HByyy, F6EFM, NA5Q e KE4WY) che hanno parlato di  guasti allo stadio PA; Come si vedrà più sotto (*) Icom, certamente, sta cercando di capire direttamente sul campo! cosa &#8220;noi&#8221; siamo capaci di fare realmente con i loro apparati, in modo da ridurre al minimo i rischi e migliorare così i loro prodotti. Allo stato delle notizie non si può assolutamente dire che questo sia un problema reale, anche perchè solo Icom con i centri di assistenza potrà rilevare le cause e valutare il numero dei casi di guasto degli MRF150 o di altro,  in rapporto al numero totale di apparati già venduti globalmente. Sarebbe anche interessante, per tranquillizzare,  se Icom emanasse un bollettino informativo con le specifiche tecniche e le eventuali soluzioni per questo.</p>
<p><strong>Interessante </strong>(*): G6PZ, Paul ha scritto il 25.07.2008 nell&#8217;IC7700-yahoogroups:<br />
&#8220;Bene questo weekend c&#8217;è il contest RSGB IOTA e saremo visitati dalla Icom UK (Regno Unito). Vogliono vedere il loro prodotto in azione &#8220;sulla brace!&#8221; per così dire. Questa opportunità è un grande feed back per il loro prodotti, dopo tutto i 7700 sono definiti the &#8220;contest radio&#8221;&#8230;&#8230;..&#8221;</p>
<p>Link to: <a href="http://www.g6pz.com/">Official G6PZ Icom UK Contest Group web page</a></p>
<p><em>August 4th, 2008 by M0CLW : </em>IOTA Contest 2008 Result: (G6PZ Team) Multi-op Fixed Island: <span style="color: #ff0000;">Claimed score</span>: <strong>8,867,718</strong> points!&#8230;. etc&#8230;. Icom UK visited us to see the contest group in action and both the IC-7800 and one of the IC-7700s worked flawlessly.</p>
<p><strong>ENG:</strong><em>They were read some of the posts (I5IHE, I1xx/Dae, VK5EME, DL7USA, LA5EKA, HBxxx, HBxyy, F6EFM, NA5Q e KE4WY) concerning PA-Unit failures, with regret as its never a good outcome when this happens, but Icom are (*) really trying to understand what &#8220;we&#8221; do to their rigs in the real world so as to minimise this and improve on their products. It is difficult to say the incidence of PA failures in the IC-7700 (as apercentage of units in global&#8230;.service), only the Icom service centres can determine this via an exhaustive examination in the course of repair. I am confident that Icom will issue a service bulletin informations to correct it.</em><strong>Interesting </strong>(*): G6PZ, Paul wrothe at 25.07.2008 on the IC7700-yahoogroups:<br />
&#8220;<em>Well it&#8217;s the RSGB IOTA contest this weekend and we are going to be visited by Icom UK. They want to see their product in action at &#8220;the coal face&#8221; so to speak. This is great product feed back for them, after all the 7700is a &#8220;contest radio &#8221; &#8230;&#8230;..&#8221;</em></p>

<p>Major points of update from Ver.1.02 to Ver.1.03: &#8221; <span style="color: #ff0000;">Improvements in the TX monitor audio<span style="color: #000000;">&#8220;  <em>The old FW (1.02) caused a great deal of background noise in the monitor audio and an AGC  characteristic that was difficult to listen to in the monitor audio.</p>

Note: I would remind  that the update file must be placed in the &#8220;7700&#8243; dir on the USB memory stick if the stick has been formatted in FAT32 by the 7700 previously, you can also format it on a PC, but it must be FAT32. To reboot turn off the front switch. NEVER turn off the power from the back without shutting down the radio first (front button). These radios should be run off a <strong>UPS</strong> (Uninterruptible Power Supply) Never cut off power supply while updating firmware! Before starting the download, please read through &#8220;Section 16 (UPDATING THE FIRMWARE)&#8221; of the IC-7700&#8217;s instruction manual. Please save the transceiver data content to an USB memory before starting the firmware update; If you want to update the firmware via LAN, please also download this Firmware update utility: 7700FirmUtl_v100.zip;<br />
The Ethernet port update method, but it should work fine if you read the directions in the manual on that topic!</span></span></span></span><span style="color: #ff0000;"><span style="color: #000000;"><span style="color: #ff0000;"><span style="color: #000000;"><span style="color: #ff0000;"> </span></span></span></span></span></p>

<strong>RadCom reviews: IC-7700. </strong> Queste le conclusioni di Peter Hart, G3SJX che ha curato la recenzione per la RSGB, in merito all&#8217;analisi dell&#8217;Icom IC-7700:<br />
&#8220;The IC-7700 is without doubt a most impressive radio. Its performance, its features and its ergonomics place it high in the top league. As a general purpose and contest radio it is excellent, but for serious DXing with split frequency operation the lack of a second channel receive capability or dual-watch is a major shortcoming, particularly with a price tag around 4,000 UK Pounds. It all depends where your interests lie as to which features are most important&#8221;.</p>
