 FTdx-1200_3000_block-diagram

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 http://www.radiocronache.com/2012/10/p4581/) – [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.

4.3.  As one would expect of a high 1st IF (“up-conversion”) superhet architecture, image and 1st IF rejection are superb (> 110 dB). These figures are unachievable with an in-band (“down-conversion”) 1st IF design.

pdf_logoLink to: Downloada the FTdx-1200 Test Report by VA7OJ, Adam (pdf)

Test A2: Reciprocal mixing dynamic range (RMDR): In this test, a strong “undesired” signal is injected into the receiver’s RF input at a fixed offset Δf from the operating frequency. (etc. see the complete pdf!)

Test Conditions: SSB mode, 2.4 kHz filter (IF DSP), preamp off (IPO), ATT off, DNR off, NB off, DNF off, Notch off, Contour off. AGC Slow, negative offset. Roofing filter: 3 kHz (R3). RMDR in dB = input power – MDS (both in dBm). The RF input power Pi is increased until the receiver noise floor increases by 3 dB, as measured at the audio output (etc. see the complete pdf!)

Δf  kHz 2 / Pi dBm -38 / RMDR dB 82 — Δf  kHz 5 / Pi dBm -30 / RMDR dB 90

4.1 It will be seen from Tables 2 (RMDR) and 3 (DR3) that at 2 kHz spacing, the measured 82 dB RMDR value values is slightly higher than measured DR3. This indicates that although the measurement is phase-noise limited, there is still a measurable component due to front-end non-linearity.
!! At 5 kHz spacing, RMDR and DR3 are 90 dB and 81 dB respectively, indicating a fairly rapid fall-off in phase noise between 2 and 5 kHz offset. (…… etc. see the complete pdf!)

4.6. As mentioned in the test descriptions above, no trace of ALC overshoot or spikes was observed at any time.  (…… etc. see the complete pdf!)

4.8. Overall, it is felt that the FTDX-1200 is a very good performer and an excellent buy in the mid price range

Noise Power Ratio (NPR) Testing of HF Receivers -© by Adam, VA7OJ/AB4OJ
Using notched noise to evaluate dynamic receiver performance

Noise Power Ratio (NPR) Testing of HF Receivers – Using notched noise to evaluate dynamic receiver performance – (…. To put the impact of the NPR test into perspective, a -9 dBm Ptot level at 5.6 MHz BRF is equivalent to 1200 simultaneous SSB signals at -43 dBm each, i.e. S9 + 30 dB!) etc. etc…. by Adam Farson, VA7OJ/AB4OJ- (!! updated in March, 2013 – see the link below)

NPR_va7oj-labsCon il Test NPR Adam, spiega che il Generatore di Rumore Bianco (W&G RS-50 il suo) immette un segnale a banda larga al connettore d’antenna e quindi carica tutti gli stati del ricevitore, il Front-end, i Filtri e l’eventuale Preselettore, simulando la risposta alla ricezione di multi-segnali del DUT in prova (come in realtà succede collegandovi un’antenna). Dice poi Adam che questo Test equivale a 1200 segnali in SSB simultanei! a -43 dBm ciascuno i.e. a S9+30 dB! – Il rumore bianco viene rimosso con una tacca alla frequenza sintonizzata del ricevitore da un adatto filtro notch, inserito in serie tra generatore e antenna imput – A causa della distorsione dei circuiti del ricevitore (DUT imput), questa tacca (notch) tende a riempirsi con prodotti di intermodulazione, i cui effetti verranno oppurtunamente misurati in uscita (DUT output). – Here is the link to VA7OJ’s FTdx-3000 FT-950 TS-590S IC-7700 and IC-7410 K3 etc. NPR testing report in PDF of March 2013.

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!) –

FTdx-3000D Leaflet: DR 106 dB, IP3 +33 dBm at 2 kHz > Sherwood Test: DR 82 dB at 2 kHz!

FTdx-3000 Test Data by Sherwood Engineering Inc. Laboratory 13 December 2012 – Rob Sherwood, NCØB has published some results for the FTDX-3000 on his Receiver Test Data – Link to: Sherwood  Receiver Test Data

Find it behind the Kenwood TS-590S because close spaced DR was “only” 82 dB and Phase Noise limited (LO Noise dBc/Hz). I wonder if Yaesu will change their advertising claims? – [Note] Rob Sherwood has an excellent laboratory, but expect certainly also QST’s test results – (The QST’s measurement process differs from the Sherwood Labs approach)!

ARRL Forum Equipment Testing and QST Test Review – Two Tone 3rd Order IMD Testing – In July of  last year WB1GCM, Bob Allison ARRL Test Engineer said:

“A third-order dynamic range test or intercept point test that is noise limited is not a valid test of a third-order phenomenon at all…. etc – Link to: Full explanation

FTDX-3000D front end: Fifteen separate band pass filters (BPF) reduces the undesired and out of band signals. In the two RF amplifier, the low NF bipolar transistor 2SC3357 is used and optimized working point.  The AMP 1 uses one RF amplifier stage, in addition the AMP2 uses two stages.

The Spectrum Scope has two modes: the auto mode monitors, and sweeps the band continually ! – Bandwidth of the spectrum scope may be set to any of six different spans: 20kHz, 50kHz, 100kHz, 200kHz, 500kHz, or 1MHz., and may operate in either Center or Fixed mode (like IC- 78 -77 -76-transceivers). The FTdx3000 also has an AF-FFT (Audio Frequency Fast Fourier Trasform) scope built-in (adgiusting the RX IF filter and the TX audio…) – Spectrum Scope Memory: 
The Spectrum Scope screen can be stored or recalled with one touch. Simultaneously the time information is recorded in the memory, so that the difference in activity may be reviewed and compared !

In the FTdx-3000D “Down Conversion” receiver construction is used. The  first IF frequency is 9 MHz. This makes possible narrow bandwidth crystal roofing filters (300 Hz ( optional), 600 Hz or 3 kHz) with a sharp shape factor that creates amazing multi-signal receiving performance.
The narrow bandwidth crystal roofing filter enhances the receiver multi-signal characteristics. (source broshure Yaesu USA)

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.
