TS-590 Kenwood USA advertising in the QST June,10 – Down conversion 11 MHz 1st IF

The Kenwood “TS-590″ utilizes Kenwood’s proven 32 bit IF DP technology – Features selectable Roofing filters at 2.8 kHz, and 500 Hz on  1st IF – including down-conversion wtih the 1st IF at 11 MHz (like TenTec, Elecraft and Vertex Standard Yesu in the FTdx-5000 series), USB port, HF and 6M Antenna Jacks, Dual VFO Display, Automatic Tuner, etc. -

Kenwood has not yet announced final features, specifications, pricing or availability. The model number is tentative! – The June QST on the back cover is TS-590S seems to be a picture of. This back cover advertisement Kenwood is, first. – The Legend Continues and there TS-520, TS-570, TS-590S and is introduced from above. TS-590S on the front panel seems to be why do the characters TS-590 missing. – The Next Generation – Coming Soon and there.

Latest rumors: Size (WxHxD mm) 270x96x291 – TX Power 100W – High Dynaming range – IP3 +30dBm class at 2KHz separation – 32bit floating-point DSP – Sky Command – USB port for PC control and Sound inteface….?? — Wait for the official news updates Kenwood!!

Il nuovo “TS-590″ utilizza la tecnologia a 32 bit IF DSP della Kenwood, ha la possibilità di selezionare due Roofing filters da 2.8 kHz e 500 Hz BW nella 1st IF, comprende la conversione in basso nella prima IF a 11 MHz (come già fatto dalla Ten-Tec, dalla Elecraft ed da ultimo da Yaesu con la recente serie FTdx-5000), prevede una porta USB, due connettorri per HF e 6m, due VFO sul Display,  l’Accordatore automatico e altre features. La Kenwood non ha ancora rilasciato tutte le specifiche effettive, nè il prezzo. Il numero del modello per ora è un ipotesi “590″!

La rivista della ARRL QST di Giugno, 2010, sul retro della copertina, riporta la prima pubblicità per il TS-590, indicato come discendente del noto TS-520 del 1973, poi del TS-570D/S del 2000 e quindi la foto che dovrebbe essere del TS-590 perchè non riporta nel frontale tale sigla (in corso di conferma!). Questo annuncio di Kenwood USA sulla IV di copertina di QST mette in primo luogo: “La Leggenda Continua”, poi in grande: “The Next Generation – Coming Soon” – Aspettiamo !

The latest Firmware Updates Ver.2.21 IC-7800, 1.12 IC-7700 and 1.02 IC-7600, of 2010/04/01

Firmware Updates IC-7800 / IC-7700 / IC-7600 – Nuovi aggiornamenti  dei Firmware di Icom Inc. – Other news: Icom have released a new Ver. IC-7600  User Manual En 1EX-3 - of 01 Feb, 2010

The DSP IF filter shape factor (-6/-60 dB). This is the ratio of the -60 dB bandwidth to the -6 dB bandwidth, which is a figure of merit for the filter’s adjacent-channel’s rejection. The lower the shape factor, the “tighter” the filter. – The two type of DSP filter shape factor for each SSB, SSB-Data and CW can be selected independently from soft and sharp.
A sharp profile with a flat passband and soft profile with a more rounded passband (Twin Passband Tuning [TWIN-PBT] is also easily provided, which enables the filter sides to be both indipendently moved and narrowed, the DSP also provides audio filtering and shaping functions). Depending on  the operating situation, for example handling a pile-up or receiving a very weak signal, you can flexibly change sharp and soft filter shapes or reduce or shift the filter width, even while receiving a signal, by a simple push of a front panel key.

FTdx-5000MP. The new Yaesu HF/50MHz 200W Transceiver and SM-5000 Monitor

FTdx-5000 Series – The new Yaesu HF/50 MHz 200W  Transceiver: FTdx-5000MP, FTdx-5000D, FTdx-5000 and the SM-5000 Station Monitor.
The Yaesu FT DX 5000 Series will be formally introduced by Yaesu very soon. Pricing and availability is currently unknown (www.radiocronache…23.11.2009)

!!! FTdx-5000 by Yaesu Broshure: 14 MHz band 2kHz offset 105 dB 3rd-IMD, IP3 +36 dBm, way better than the Elecraft K3 @ 102 dB IP3 +26 dBm!

The FTdx-5000 (Main Receiver only) includes a rather traditional 1st IF 9 MHz (Elecraft K3 1st IF 8,215 MHz) and provides for selectable roofing filters (6-pole crystal) at the first IF to limit the off-frequency signals getting into the receiver.
Note that the roofing filter’s job is only to protect the rest of the receiver, and that the operating bandwidth filtering is performed by the IF DSP (like Elecraft K3 Transceiver).

[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: 1st analog mixers, 2nd IF I/Q rejection mixer and DSP – Download Broshure Eng. and USB Driver Installation Guide

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.

IC-7600 User Manual in English is released. Here now at least you can read the new features summary

User Manual in English version for the IC-7600 is released by Icom Inc. Jp.
Here now at least you can read the new features summary by www.radiocronache.com® —- (See the Link below for download User Manual)

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.
Sets the input modulation level of the [USB] connector from 0% to 100%  in 1% steps on the Level set mode. The received audio output level from [USB], cannot be adjusted with the [AF] control.

R&S® M3SR Series 4100 SDR HF Radio Family – Analog mixers and digital IF and audio signal processing

Rohde & Schwarz M3SR® Series 4100 of HF radios represents a new, innovative and versatile generation of software defined radios (SDR).

Rohde & Schwarz ha sviluppato una serie di apparati di nuova generazione per i sistemi di comunicazione professionali, tipiche applicazioni a bordo ni navi, per il controllo di traffico aereo, per ambasciate e per applicazioni tattiche militari. Da quanto si legge nella broshure la struttura della R&S® M3SR Series 4100, pur definita a ragione SDR, sembra andare ancora sul sicuro. Niente RF Sampling (ADC/FPGA), ma impiego combinato della collaudata tecnologia RF analogica (Analog Mixers), dove R&S® è eccellente da sempre, seguita  da una seconfa IF a 48 kHz che viene campionata, digitalizzata e processata con l’impiego dei recenti sistemi DSP numerici implementati R&S® all’interno del’apparato.  (Per esempio si potrebbe dire una struttura a due conversioni + IF DSP simile a quella del’ IC-7700 reiterata da Icom anche sul nuovo IC-7600! in arrivo)

ENG: The R&S® M3SR Series 4100 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, digitized and processed using digital ignal processors. This means that a wide range of IF bandwidths is available in all modes with high selectivity and optimized for voice and data communications. Digital signal processing also provides functions for noise suppression. The individual radio lines can be occupied by any of the waveforms supported by the R&S®M3SR Series 4100   including:
Voice (SSB, AM, FM) – Radio teletype (RATT) – Modem (STANAG 4285, STANAG 4539) – Automatic link establishment (ALE-2G/3G) – Tactical data links(Link-11, Link-22)

FK4120/4140 è  un rimarchevole sistema di preselettore – optional plug-in modules -  con cinque circuiti LPF da 0 Hz a 1.5 MHz e poi digitally tracking bandpass filters da 1.5 MHz a 30 MHz con 20 dB o 40 dB edge steepness at 10 % frequency offset. Questo per accrescere la selettività dei canali sia in trasmissione che in ricezione. Si migliorano molto i parametri di IMD di 2nd e 3rd ordine, la rejezione di IF e di immagine, l’immunità alla modulazione incrociata. Nella diretzione TX il rumore di fase viene soppresso con un basso valore tipico migliore di -165 dBc/Hz !   (Per esempio, negli RTX per Radioamatori, si può trovare il DIGI-SEL  Unit, Icom o il VRF+ uTune, Yaesu che combinati con gli ATU Unit, possono avere funzioni e performance abbastanza simili! )

ENG: The R&S® FK4120/FK4140 digitally tuned HF selectors are optional plug-in modules for the radios of the R&S®M3SR Series 4100. They increase the selectivity of the transmit and receive paths. Receiver parameters such as 2nd and 3rd order intercept, IF rejection, image-frequency rejection and crossmodulation immunity are significantly improved. In the transmit direction, the TX phase noise is suppressed to produce typical values as low as –165 dBc/Hz.
- Five-circuit lowpass filter (0 Hz to 1.5 MHz) for receive frequencies below 1.5 MHz
- Digitally tuned tracking bandpass filters (1.5 MHz to 30 MHz) with 20 dB or 40 dB edge steepness at 10 % frequency offset. – (for Ham radio See the DIGI-SEL  Icom or VRF+uTune Yesu + the ATU Units)

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)
