QST reviews FTDX-1200 on January, 2014 vs VA7OJ’s NPR test – FTDX3000 Update Software Main V0115 & TFT V0108


QST reviews the FTDX-1200 on Januaru, 2014, a overview of the YAESU 100W HF/50MHz Transceiver. –  ARRL labs including  81 dBc at 2 kHz RMDR (Reciprocal Mixing *) figure on 14MHz band, 3kHz roofing filter & 500Hz bw. See the complete Test report & NPR test by VA7OJ, Adam (82 dBc at 2kHz RMDR) link below. – FTdx-3000  Firmaware update: Main Ver.0115 and TFT Ver.0108 (11/19/2013).


Dynamic range (blocking, IMD and Reciprocal Mixing, related to Local Oscillator noise*) is a major limitation of receiver performance. It’s significant for amateurs who operate in contests, DX pileups, or others environments in which there are many strong nearby signal. – The Reciprocal Mixing Dynamic Range* (RMDR) is noise generated in a superheterodyne receiver when noise from the local oscillator (LO) mixes with strong, adjacent signals.

italianoLo FTdx-1200 condivide l’aspetto esterno e le dimensioni del fratello-cugino FTdx-3000 che però utilizza la down-conversion in IF.  L’FTdx-1200 ha una diversa architettura per il circuito del ricevitore con la up-conversion in IF. – Come evidenziano anche i test di QST e di VA7OJ, Adam l’FTdx-3000 presenta numeri più performanti, l’FTdx-1200 ottiene valori riscontrabili, sia nel FT-950 che in  molti altri ricetrasmettitori recenti di costo medio basso. Quindi si può dire che si presenta con buone prestazioni, ma non fino ai livelli del ‘3000 o del ‘5000 dello stesso produttore! –
A parte per l’FTdx-5000 il tema: “OLED Display Dead” This saga will continue! The new mystery is why the dreaded white line  (link – [Note] FTdx-5000 Firmware Updates: The last upgrade i did was EDSP V.0546 and Main V.0124 (9/4/2013)

italianoSpectrum Scope & FFT-1 Unit (optional)
Il FTdx -1200 con il suo Display a colori da 4,3″ TFT offre una analisi di spettro che opera in una modalità intermittente. Cioè, automaticamente e in modo veloce (300 ms) sottrae una frazione al ricevitore e fa la scansione (sweep), bloccando l’audio del ricevitore. – Tra le veloci scansioni , mostra l’ultimo “snapshot” prelevato nell’intervallo settato (in due modi Select or Auto mode). –  Se si acquista la scheda opzionale FFT-1, la portata dello spettro può anche funzionare come un oscilloscopio per osservare attentamente sia il segnale audio ricevuto, sia il segnale audio trasmesso con il dominio del tempo in frequenza (cascata = waterfall) (AF FFT Audio Frequency Fast Fourier Transform). L’Unità TFT-1 permette anche la decodifica e codifica interna di RTTY, PSK31 ed anche CW (telegrafia) con messaggi visualizzati sul Display TFT e memorie. (ed altro!)

italianoPorta USB e interfaccia SCU-17 (optional)
SCU-17_USB-Interface-2Per l’utilizzo dei nuovi computer dotati di sole Porte USB, invece dei vecchi connettori seriali (RS-232), Yaesu offre in vendita la “SCU-17 USB Inteface Unit”.

Oltre a fare da adattatore Seriale/USB-2, semplifica le operazioni radio in modo Dati e RTTY con l’audio In/Out e CAT control via porta USB-2 e però servono cavi adattatori vari per i collegamenti.

FTDX-1200 Firmware Updates – Main CPU Ver. 01-15 and TFT Ver. 01-08

FTdx1200 upgrade V-0115_V-0108

FTdx-1200 New Firmware Update – Main CPU Ver. 0115 and TFT Ver. 0108 has just been posted 11/19/2013 by YAESU USA on his web-site. – Please read the  Yaesu FT3k Firmware Upgrade Manual & Yaesu Information before proceeding!

[Note] There are four different Software installations (Yaesu still uses the multiple software systems installations! on the FTdx-3000, Icom and Kenwood instead use a unified software environment) – Each one must be followed carefully. – Installing the wrong type software may cause difficulties. !! You are only doing the Main-CPU and TFT updates.
[Note] The rig has to be started in different ways for each of these two updates to work!  The Yaesu “Firmware Upgrade Manual” has the update procedure for all of the Firmware-Modules & extention type (MAIN .SFL – DSP .dat – TFT .bin – FFT .dat), and for all Trasfer-Softwares (!!

FlexRadio projects in early Q2 2013 start of deliveries: Gerard Youngblood, K5SDR FlexRadio CEO (latest Flex Insider-6):  ….. “Next, how to you make an extremely complex radio simple and intuitive to use? Leonardo Da Vinci once said, “Simplicity is the ultimate sophistication”. “Complex is easy, simple is hard”. …… Progress is visible and accelerating. Everyone is motivated, excited about what we are building, and working hard…. etc. ! – (See link below to more news!)

Flex Radio Booth at HamCation Orlando 2013– (by videosbymike


Il Team-Marketing di  FlexRadio ha preparato quest’altro Video  che mostra più in dettaglio alcune funzionalità della loro nuova interfaccia utente detta “SmartSDR” –
Il video inserito qui sotto è ricavato da una registrazione dal vivo effettuata da K5FRS con l’hardware del FLEX-6700 in corso di produzione e su cui girava proprio il Software “SmartSDR” in fase di implementazione da parte degli ingegneri FlexRadio-

Imagine a real time spectral display where the noise floor is averaged to the terrestrial noise floor. – By real time, I mean that the display follows the instantaneous power of the signal but the noise floor is almost a flat line (no “grass,” as we call it) at the noise level seen at the antenna. This remains true whether zoomed out to view half of the HF spectrum or zoomed in to just a few kHz.
[Note] The “PacMan” looking signal that flies through the bands is a Propagation Ionosonde Station located a few miles from FlexRadio Factory!

Minimum Discernible Signal (MDS and NF) – How LOW do you GO? – by Greg Jurrens – K5GJ, VP, Sales & Marketing There’s been a lot of talk these days about Minimum Discernible Signal, or MDS. What is it? What affect does it have on my receiver performance? Why do I care? – …. “The ARRL labs use a procedure to measure MDS to a signal 3dB above the noise floor (NF) measured in a 500 Hz bandwidth.

!Amplifiers are very good at amplifying… Everything – signal, and noise. We want the signal but not the additional noise that comes along for the ride. Ideally, the amplified MDS should be 3 to 6db below the environmental noise floor. Plus, the amps themselves add a bit of noise to the mix. Worse yet, using pre-amplifiers have a cost of actually LOWERING the radio’s effective dynamic range. Dynamic range is defined as the difference between MDS and input overload. The pre-amp’s gain comes right off the top of that number. In this case, too much is not just right.

The FLEX-6000 Signature Series to the rescue! – One of the unique features of the Spectral Capture Unit (SCU) of the FLEX-6000 is the Digital Variable Gain Amplifier (DVGA). This allows the software to vary the SCU’s front end performance in 0.5dB steps from -11.5dB up to +20dB of gain (up to 40 dB on the FLEX-6700 with the additional +20dB second pre-amp). The result is the perfect MDS for your QTH and situation. Just enough gain to coax the signal out of the noise, but not so much that all you hear is noise or give up dynamic range. This capability will be provided for advanced operations. Again, the flexibility of a SDR (Software Defined Radio)…. etc”  Link to Source: FlexRadio Systems (Flex Insider – Issue-5 and 6)

Da Flex Insider Issue-5 /2012…..A proposito delle discussioni tecniche in corso sul MDS/NF (Minimo Segnale Discernibile a +3dB sul rumore o Noise Floor)  Una delle caratteristiche uniche del circuito “Spectral Capture Unit” (SCU) incorporato nella Serie  FLEX-6000’s è anche l’Amplificatore di Guadagno Digitale Variabile (DVGA). Questo sistema permette al software di variare le prestazioni del Front-end della SCU a passi di 0,5 dB da -11.5dB fino a +20 dB di guadagno (fino a 40 dB sul FLEX-6700, con l’ulteriore +20 dB del secondo pre-amp)…. così da adattare al meglio la MDS in base alle condizioni del QTH….etc.

The authors write: To say that the KX3 is a Direct Conversion Radio misses the point. It would probably be more descriptive to say that the KX3 is a Software Defined Radio (SDR) with a Ø Hz IF and I/Q quadrature component receiver processing that provides single-signal reception. Those signals allow a PC running your SDR software to display the spectrum and usual rig control management. – Elecraft provides your choice of a cable that connects to a PC USB2 port or an RS-232 socket (add. $29.95 or so!) –

Icom RS-BA1 Ver.1.30 – RC-28 Remote Encoder – Legal aspects! Rig Monitoring a different purpose

The new RC-28 Remote Encoder accessory gives users a tactile approach to the RS-BA1 Remote Control. Icom has released the Ver.1.30 !! – The RS-BA1 allows you to use the radio installed in another room using your home network or even from a remote location over the Internet. – (operator not physically present in the Remote Rig) – See the legal aspects below – Info to Rig Monitoring  on the Computer Screen (For Vision-Impaired Ham Radio op.) – See the Link below.

RS-BA1 [Note] ….Visual Basic and use MSCOMM control can not detect a change in the Windows Device Table (after the COM port has been opened for use) – These programs hang when the hardware table changes while the port is open – (This is not the programmers fault!)
!! a solution: [Exit] the program first, then turn the Icom Rradio [OFF].

[Note] Legal aspects! (FCC – CEPT – DXCC par. 9) see related link below; – Why remote? and many helpful references by John, KØIZ, read August 2012 QST Magazine ( pg. 39-40)! – (operator not physically present in the country and transnational remote operation, DXCC rules ref. to remote operation and credit etc.)

Link to: ARRL Guide by WA8IMY Remote Operating

Now Icom comes out with a great new gadget, RC-28 a little box with a VFO knob, 2 programable buttons and a PTT button. The RC-28 is designed to connect to a PC through a USB port, and operate with the RS-BA1 IP Remote Control Software. – Supplied a USB cable (approximately 1.5 m; 4.9 ft) – (RC-28.. like Tmate USB Tuning System …by WoodBoxradio)
[Note] – 1) Make sure Windows has completed its start-up on PC. – 2) Connect the RC-28 to the PC that has RS-BA1 Ver.1.30 or later version installed on it. When the “USB dial…” item on the [Option] menu is not displayed, Please download the RS-BA1 latest version 1.30 from the Icom website, and install it.
[Note] Please read ICOM RC-28 instructions (leaflet PDF) thoroughly before using it.

Link to: Icom RS-BA1 /RC-28 brochure (update 12PS0230)

RS-BA1 Remote Control Software Upgrade Ver. 1.30 is now downloadable from the Icom co.Jp site. – This upgrade is not stand-alone, and must be installed over a licensed base installation of RS-BA1. (Update, the remote utility is still V.1.2 but the remote control is V.1.3!!) – US Retail price RS-BA1 software is $129.99

[Notes]: DO NOT allow the PC to go into the sleep or standby mode while using the RS-BA1 Software. Otherwise, it might not work properly after the PC resumes normal activity.
When not using the radio: Disconnect the radio from both the Remote Utility and Remote Controller. – Even if you disconnect from the radio, it does not turn OFF the radio!

Since cannot turn the radio ON or OFF with RS-BA1 Remote Control operation, the radio must be turned ON. – [Note] there other control board and software (no Icom) to control power to equipment or other options, it works together with Icom RS-BA1 or HRD software etc.

FT-450D HF/50MHz Tranceiver, Product Review, QST, 11/2011 by Mike, W5MPC

Yaesu FT-450D HF/50MHz Transceiver, Product review, QST, November 2011. Reviewed by Mike Corey, W5MPC. – Following in the line of the FT-100D, FT-817ND, FT-857D…. arrived it the FT-450D!

The FT-450D adds a standard internal ATU that cover the 6 to 160 meter bands (operation is very easy), and several ergonomic upgrades to the original FT-450. – New knob design, new standard hand mic., Button illumination and 500 and 300 Hz CW filters. (…please click the thumbnail to enlarge!) – See …..the link below !

QST Key summary 20m only: 500 Hz bw, Pre-off… 20 kHz spacing blocking gain compression 134 dB / IMD3 20 kHz 97 dB / IP3 +17 dBm. – FT-450D performance is about the same as the previous ‘450! – See the November 2011 issue of QST magazine for the complete review and ARRL Lab test results (members only….login)

A big improvement to the front pannel is backlighting for the buttons, strong enough that buttons can be seen from several feet away ub a dark room, and a significant improvement over the CW filter in the previous FT-450 Transceiver.

QST reviews the TS-590S on May, 2011 – Top class performance at a middle price

QST Magazine reviews the TS-590S on May, 2011 by N0AX, H. Ward Silver . The review radio originally shipped with firmware Ver 1.00 (S/N B0900113 September, 2010) but was upgraded to firmware Ver. 1.02 for final testing on the ARRL Laboratory.

N0AX also writes: The TS-590 is a very interesting superhetero-dyne that operates as either a double-down conversion (RX1), used on the 160, 80, 40, 20 and 15 meter bands for SSB, CW and FSK only; Triple up-conversion (RX2) chain on other bands, including 10 and 6 meters is used for wider IF BW such as for AM and FM, in addition to the SSB, CW and FSK.

Source: QST reviews, we show only the figures at 14 MHz, Pre OFF ( K3 /  TS-590S)

  • …………………………………………..Elecraft K3………………..Kenwood TS-590S
  • ………………………………………...QST Jan 2009……………………..QST May 2011
  • ………………………………………..In both operate with a double down conversion
  • ……………………………………(400 Hz, 8-pole roofing)………(500 Hz, roofing filter)
  • Band: 14 MHz – Pre Off
  • Spacing 20 kHz blocking gain compression….142 dB…………………….141 dB
  • Spacing    2 kHz blocking gain compression….140 dB…………………….121 dB
  • Spacing 20 kHz 3rd-order dynamic range……106 dB…………………….106 dB
  • Spacing    2 kHz 3rd-order dynamic range……103 dB………………………97 dB
  • Spacing 20 kHz 3rd-order intercept…………..+29 dBm………………….+26 dBm
  • Spacing    2 kHz 3rd-order intercept…………..+28 dBm………………….+22 dBm

I found the adjustable AGC action to be quite clean — no clicks, thumps or pops. It’s possible for a very close signal to be inside the roofing filter but outside a narrower DSP filter, causing the audio level to fall dramatically, but the signal has to be really close.
When either NR system is turned up to its most aggressive setting audible artifacts are created (NR2 artifacts sound like the band is “boiling”) but both are far better than the noise they have replaced.

The only problem I encountered was a significant power overshoot on the leading edge of a first dot or dash before recovering to the intended level. That caused the ACOM Series amplifier to trip offline unless we reduced drive, dropping amp output to 800-1000 W. – The problem was eliminated by a Ver. 1.02 firmware upgrade  from Kenwood and verified by testing with the same amplifier at W1AW at the legal limit. —

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 !
