IC-9100: Interior views, features summarized, first impression, dual receiver but not same band, limits  EMCOM. High price to base, and many optionals  required for full operation. How to Expand the Receiver range.

Icom V.10GS0190 brochure and it looks like the dual receiver works in all modes simultaneously, but not on the same band • The IC-9100 has 3 independent receiver circuits from the antenna connector to the 2nd IF image rejection mixer • The IC-9100 will receive simultaneously (with mixed modes if desired) on any of the band pairs shown in the “Independent dual receivers” table on the IC-9100 brochure • It severely limits the usefulness for Emergency Communications (EMCOM) by not being able to monitor the same band with both receivers • For that matter, it limits if for DX and contesting, where you are listening in two places of the HF band at the same time. • The architecture of the IC-9100 (only one 1st mixer and LO per receive chain) precludes same-band Dual Watch operation.

The optional UT-121 Unit provides D-STAR DV mode digital voice and low speed data communication. [Note] It doesn’t have the Icom ID-1′s DD “high-speed” data feature!  - Installing the optional UX-9100 box and his IF PCB the IC-9100 fully covers the HF/50, 144, 430/440 and 1.2GHz amateur bands in multiple modes. – RX expansion range (see last picture above): Frequancy coverange (not guaranteed!) 30kHz to 60MHz / 108 to 174 MHz / 420 to 480MHz 7 1240 to 1320MHz – Disassemble the radio, locate diode matrix behind the front panel and remove D1504 and D1505 for full Rx coverage, !! work with great care, risk of damage to the PCB – Assemble the radio and operate the full reset by olding [F-INP-ENT] + [M-CLR] and turn power [ON].
[Note] Before you do anything, please read this.!
The modifications are not verified, so if you try some of the article on your own equipment, it’s on your own risk. Performing modifications of some equipment may be a violation of local laws. If you have any doubts, do not perform the modification.

TS-590S G3SJX reviews the Kenwood HF/50MHz transceiver RadCom 01/2011

20/12/2010

Kenwood TS-590S Peter Hart reviews the latest HF/50MHz transceiver on ©RadCom January 2011 – The RSGB Radio Society of Great Britain Members’ magazine.
The figures measured of RadCom  are excellent, similar to or better then top-end radios costing two to four times as much!

Here follows a short summary by © www.radiocronache.com taken from ©RadCom 01/2011 – (View the 01/2011 ©RadCom Magazine to read the full review by Peter Hart. A large and very interesting technical work, thanks) –
Link t0: RSGB Abaut RadCom and news web-page (-Members’ only)

The TS-590S is a single receiver tuning 30 kHz to 60MHz, although the performances is specified within the amateur bands. – The menu system is very comprehensive with 88 items, it uses scrolling display annotation. – Menu items allow for both fast and slow linear switching separely for HF and 50MHz but there is only one linear control line. - For use with transverters, the display can be set to indicate the trasverter frequency.  Three digits are available for the MHz segment, eg 144 or 432.

Measurements – Peter evaluates separately two path: RX1 down-conversion and RX2 up-conversion.  ————– (Short summary data)
The rejection of IFs and image for the RX1 down-conversion path was typically 75dB to 90dB (1*) – For the RX2 up-conversion path these figures were typically better than 90dB. – He searched carefully for other spurious responses as DDS circuits tend to be prone to this problem. – RX2 was very clean with no responses less than 80dB down. – RX1 was exceptionally clean with no other responses less than 100dB down (2*).
- (1*) FTdx-5000 the 9MHz IF rejection on 10MHz it was only 54dB, and on 7MHz it was 74dB. - (2*) FTdx-5000 the first mixer image was only down by 55dB to 70dB (>RadCom  June, 2010 review)

IP3 Intercept and IMD3 Dinamic figures for bands (1.8 3.5 7 14 21 MHz) that use RX-1 the measurement was made 2.3kHz bandwidth. By measuring in 2.8kHz  bandwidth all bands (1.3 3.5 7 10 14 18 21 24 28 50 MHz) use  RX2  path.
—– RX1 path USB mode (50kHz Spacing)
7MHz Preamp OFF – Bandwidt 2.3kHz: IP3 +31dBm IMD3 105dB
7MHz Pream ON —  Bandwidt 2.3kHz:   IP3 +22dBm IMD3 105dB

—– RX2 path USB mode (50kHz Spacing)
24MHz  Preamp OFF – Bandwidt 2.8kHz: IP3 +18dBm IMD3 98dB
24MHz Pream ON – Bandwidt 2.8kHz:    IP3 +6.5dBm IMD3 96dB

Close-in IP3 and IMD3 figures were made in 500Hz bandwidth with RX1 on 7MHz and RX2 on 10MHz.

- RX1 uses the 500Hz bandwidth roofing filter. – RX2 the 2.7kHz bandwidth filter at the second IF and 15kHz rofing filter at the first IF. - The results for RX1 path are really excellente, achiving 103dB IMD3 at 2kHz spacing and 90dB at 1kHz! – The results for RX2 path show the efect of the wider roofing filters (15kHz+2.7kHz). Then at 2kHz and below the signal enter the second IF filter passaband and the AGC takes effect.
—- RX1 7MHz Preamp OFF CW mode – DSP Bandwidt 500Hz – IF Roofing 500Hz:
2kHz sapcing IP3 +23dBm IMD3 103dB / 10kHz spacing IP3 +30.5dBm IMD3 108dB

—- RX2 10MHz Preamp OFF CW mode – DSP Bandwidt 500Hz – IF Roofing 15kHz and 2nd IF  2.7kHz:
2kHz spacing IP3 IMD3 see text below / 10kHz spacing IP3 +21dBm IMD3 103dB

A somewhat complex AGC system is used, detecting signal level in three places within the DSP signal path. – The close-in strong signal performance in some cases may be limited  by the AGC  when a strong signal falling inside the filter roofing but still outside  of the final channel filter will result in AGC action. – This can be heard as a quietening of the receiver from a very strong signal  just outside of the channel passaband. - The effect is most noticeable with the wider roofing filters and is not an issue with the 500Hz roofing filter in circuit. – [Note] clik the thumbnails to enlarge!



FTdx-5000 Review from RadCom June 10 by G3SJX – Here only some data and a summary

11/06/2010

FTdx-5000 measured performance Source: RSGB RadCom  June, 2010 by G3SJX – Table 1*
[*Note]: here, only some of the many performances misured – View the RadCom Magazine to read the full review by Peter Hart) – !! IP3, IMD3, and Blocking figures were outstanding with the appropriate Roofing filters selected. !! The only area for concern is the receiver spurious signal rejection….

Sensitivity SSB 10dBs-n:n 7MHz band: IPO-1 →0.7uV (-110dBm) PREAMP-1 →0.18uV (-122dBm) PREAMP-2 →0.09uV (-127dBm)

Close-in Intermodulation on 7MHz Band 500Hz bandwidth CW IPO-1:
Spacing2kHz (15kHz Roofing) IP3 -8.5dBm IMD 77dB – (6kHz Roofing) IP3 -4dBm IMD 80dB – (3kHz Roofing) IP3 +33dBm IMD 106dB – (600Hz Roofing) IP3 +37dBm IMD 109dB

The 9MHz IF rejection on most bands was greater than 100dB, but on 10MHz it was only 54dB, and on 7MHz it was 74dB. VRF front-end tuning improved these figures by 20dB. The first mixer image was only down by 55dB to 70dB but VRF improved this to better than 75dB.
Spurs on the synthesiser resulted in a number of unwanted receiver responses, notably at approx +/- 425kHz from the received frequency at only 65dB down on the VFO-A rx and at +/- 40kHz down by 85dB. VRF improves these figures but only marginaly on the higher bands.
Third order intercept (IP3), dynamic range (IMD3) and blocking figures were outstanding with the appropriate Roofing filters selected (See the Table-1*). The VFO-B receiver dynamic range is nont quite as good as the VFO-A receiver but is still very respectable.

Link to: The RSGB webpage – RadCom Magazine

La rejezione IF a 9MHz per la maggior parte delle bande risulta superiore a 100dB, ma sulla banda dei 10MHz scende a soli 54dB, e sulla banda dei 7MHz risulta 74dB.- L’uso del VRF tuning del front-end migliora queste figure di circa 20dB. L’immagine del primo mixer risulta attenuata solo da 55 dB a 70 dB, ma con il VRF si ha un miglioramento al valore di 75dB. Le spurie del sintetizzatore produce una serie di risposte indesiderate al di sotto di soli 65dB  rispetto all frequenza  ricevuta,  in particolare a circa +/- 425kHz dal centro della frequenza  sul VFO-A (main rx), ed ancora a +/- 40kHz sono al di sotto di 85dB. L’inserimento del circuito VRF migliora queste cifre, però solo marginalmente sulle bande più alte di frequenza.
L’intercept point di terzo ordine (IP3), la gamma dinamica  IMD3 e la dinamica di blocco hanno valori che variano in base alla banda passante  del Roofing filter selezionato (Vedere Tabella-1*). Il ricevitore del VFO-B (sub rx) ha a sua volta una dinamica non altrettanto buona come il  ricevitore VFO-A (main rx), ma comunque è  molto rispettabile. – !! Emerge dall’articolo di Peter  Hart una questione che lo preoccupa:  la effettiva capacità di rejezione di segnali spuri del  ricevitore A.

IC-7600 Review: User Evalutation & Test Report by Adam VA7OJ/AB4OJ. – I could not find any fault with the Transceiver

03/04/2009

New IC-7600

IC-7600 Review by VA7OJ : Download the fine User Evalutation & Test Report (PDF format) with the Link below or clik on the Banner  below -
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

va7oj's-shackOn 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.IC-7200-manpack-styling
———————————————————————————————
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®]

Switch BOX: is a automatic T/R switch senses for RTX and your SDR

09/07/2008


Switch BOX della Elad: è una unità di commutazione dei collegamenti d’antenna tra un RTX ed un ricevitore SDR separati. Distribuita da WoodBoxRadio di IK3VIG, Beppe, è dotata di sensore di RF trasmessa (100W max)  che permette l’uso di un Ricevitore SDR come il PERSEUS, unitamente ad un qualsiasi Transceiver HF in modo automatico tramite un relay interno, che mette a massa l’antenna RX durante la trasmissione.  L’unità Switch BOX, consente di gestisce anche i segnali audio provenienti dal ricevitore o dal monitor del trasmettitore, permettendo un rapido ed agevole confronto di ascolto tra i due segnali così ricevuti. Usando la CAT dell’RTX, con una partizione di software sul PC per la funzione di sincronismo trà l’RTX e il Perseus, si ottiene un nuovo e performante transceiver.  Protezione: Switch BOX è dotato di uno scaricatore a gas che si inserisce sull’ imput di antenna.

ENG: SWITCH BOX by Elad, is a automatic T/R switch senses transmitted RF (100W max) and switches your
antenna from SDR receive (PERSEUS)  to transmit using a relay. It shorts your receiver antenna input to ground to protect your SDR (Official distribution by WoodBoxRadio, IK3VIG, Beppe). Instead of using RF sense to switch the antenna, a control line input lets your key/keyer or PTT line switch the antenna. A complete switch control is available for the audio path of receiver and transceiver. Using CAT of your RTX, with third parts software which provide a SYNC function between RTX and your Peseus SDR, you can make an outstanding and high performance transceiving operations. Protection: The SWITCH BOX provides gas discharge protection on the antenna input.
