Icom IC-7851 vs IC-7800 upgrade modelv.3.00 Phase Noise Characteristics and RMDR (Reciprocal Mixing Dinamic Range) Characteristics in Receive Mode, data and pictures taken by videos of Icom Japan (see info and… lincks below).

IC-7800-IC-7851

Phase Noise Characteristics in Receive Mode:
Measuring conditions: Receiving Frquency 14.200 MHz, Mode CW, 1st LO frequency 78.655 MHz (1st IF 64.455 MHz Supereterodina up-convertion type)

IC-7851 v IC-7800 ver. 3.00 the RMDR Characteristics
Measuring conditions:  BW 250 Hz,  Roofing Filter 15 kHz!
See the video below: 1st step: a weak CW signal is received, 2nd: a strong signal is receiver on the same frequency, 3td step: move generator distance from center frequency: 100Hz / 200Hz/… 2kHz / 10kHz etc. (the CW signal cannot be eard or be clearly eard again) …What a difference. Impressive! (…thanks to jboyd00 for the his many videos)

Icom’s engineers focused on a new Local Oscillator (LO) in the IC-7851′ that drastically reduces the phase noise. As a result of this design, the purity of the LO achieves a Reciprocal Mixing Dynamic Range (RMDR) of 110dB!

TS-990-upd-V110-evidenza

TS-990S firmware has been updated to Version 1.10 with new NB2 Type A or B!

TS-990S Firmware has been updated to Ver.1.10 with the two [NB2] Type A or Type B – The noise blanker function (NB1/NB2) is equipped with digital (NB2) and analogue (NB1), now the [NB2] can be selected in Type A (conventional algorithm) and Type B (newly added algorithm) …and more.

TS-990_upd-110_12mag2015

I think there is merit in doing that (now upgrading the DSP), but both the implementation and the explanation of the TS-990S original firmware was clearly lacking ! V1.10 works fine here.. how well it works on a crowded band will need to be evaluated by operating  time and setting!

TS-990S/D のファームウェアが、Ver.1.10にアップデートされました – The Kenwood TS-990S Ver.1.10 updates the following features (! ….in summary).
1) Now if NB2 [Type B] is selected, the “WIDTH” (width of the pulse noise blanking) and “DEPTH” (depth of the pulse noise blanking) parameters can be adjusted to appropriate levels.
[Note] The [TYPE B] is not applied to the SUB band due to limitations of the DSP memory capacity!
2) Changing of the IF filter passband is enabled by rotating the [HI/SHIFT] / [LO/WIDTH] knobs while transmitting, via setting the Menu No.8-01 in ON or Off (TX Audio Waveform Display or Not) – (! please read the official page by Kenwood)
Revises the following symptom.
1) When playing and transmitting a stored CW messages with text entry, the consecutive space characters for intervals are deleted. – Read the Kenwood page (link below)

Factory-TS990_08-09-10
Kenwood’s Communications Division The TS-990 Factory at Yamagata Japan

italianoIl Kenwood TS-990S è già dotato di due NB (Nois Blanker) il NB1 analogico e NB2 digitale, essi ora sono selezionabili in NB1 oppure NB2 o entrambi NB1+NB2 e questo distintamente per MAIN e SUB Receivers.
Con il nuovo firmware Ver.1.10 rilasciato, pressato più a lungo il [Tasto NB2] si abilita l’ulteriore selezione e settaggio in NB2 [TYPE A] (con algoritmo convenzionale) oppure in [TYPE B] (con nuovo algoritmico aggiunto) usando il  [Tasto F6] che appare nell’icona del  Display per la nuova funzione.

In’oltre se è selezionato [NB2 Tipo B], i parametri di [WIDTH] (larghezza del rumore impulsivo blanking) e il [DEPTH] (profondità del rumore impulso blanking) possono essere regolati ai livelli più opportuni. – Pressando a lungo il Tasto NB2 oppure il Tasto ESC si chiudono le indicazioni di settaggio NB2 – [Nota] Queste nuove funzioni non si applicano al SUB Ricevitore a causa del limite della memoria del DSP.

Penso che si deve dare merito a Kenwood di aver fatto ora l’implementazione del sistema DSP, e che c’è la spiegazione che il firmware originale del TS-990 era chiaramente carente. – Ora funziona bene,  quanto bene funzioni su una banda affollata però dovrà essere valutata col tempo di funzionamento e operativo e con le varie impostazione!

Altra novità della V.1.10 consente di variare il filtro passabanda con le manopole [HI/SHIFT] / [LO/WIDTH] in Tx (trasmissione) con le indicazioni o senza sul Sub dispaly, e questo tramite il Menu n. 8.01 (in ON oppure in OFF etc.)-

JVCKenwood risolve ora anche la questione del CW con messaggi pre-settati contenenti spazi di intervallo in sequenza, ora non vengono più trasmessi perchè cancellati – (! Attenzione: leggere tutte le informazioni e i dati nella pagina web di Kenwood …in Inglese !)

A proposito di parametri di test e di confronto nei vari ricevitori per HF di tipo supereterodina tradizionali oppure di tipo digitali SDR leggere quanto scrive Adam come riporto qui sotto e poi su QEX n. 3-4 2015.

QST April 2015 reviews the FLEX-6300 nad FLEX-6700 two SDR Transceivers products FlexRadio Systems made in USA (! Note: to access this resource you need to ARRL log-in)

QST-3-2015I tradizionali valori di DR3 (3rd-Order Dinamic Range dB), IP3 (3rd-Order Inrcept Point +/- dBm) e di Dinamica di blocco (Blocking Gain Compression dB) sono “numeri” poco validi nel contesto di una radio SDR a campionamento diretto. (-dBFS per un ADC converter) –
Per questo, Adam Farsom, VA7OJ ha proposto di usare come standard il metodo IFSS (Interference-Free Signal Strength) per il test IMD (Two-Tone Intermodulation Dinamic Range) in ricevitori a campionamento-diretto (Direct-sampling SDR). – Adam, VA7OJ wrote a terrific article in the latest March/April 2015 issue of QEX Magazine. – I wish ARRL would standardize on tests, and preferably use the (NPR) Noise Power Ratio test methodology.
