Con l’uso del AMBE+2 vocoder in FDMA, C4FM raggiunge una ottima qualità audio, pur operando con un “bandwidth” effettiva in un canale di 6,25 kHz ● “V/D Mode” Simultaneous Voice/Data 6,25+6,25 kHz. – Anche se ci vuole un po ‘di tempo per abituarsi alla voce digitale, chi usa il modo D-STAR (con AMBE-2020 vocoder) già conosce l’effetto di voce robotica!.
In FDMA con AMBE+2 vocoder i benefici di qualità audio dovrebbero essere migliori almeno nel modo “FR” su 12,5 kHz  ● “Voice FR Mode” Voice Full Rate uses the entire 12,5 kHz bandwidth to trasmit digital voice.

I requisiti della norma europea armonizzata EN 301 166-2 (come lo standard ETSI TS102 490 e TS102 658) prevede la garanzia di protezione per circa 60 dB per l’adiacente canale a 6.25 kHz e 70 dB per il canale successivo.

FDMA_Mod-Dem-specModulation with 4FSK (C4FM) 4-level FSK uses a symbol mapping scheme. When the radio receives a binary number, that number is apped to a symbol, which is interpreted as a 1050 Hz frequency deviation. During demodulation, that deviation is detected, filtered and “unmapped” as a binary signal for transmission. – (click pictures to enlarge)

[Note] !! The D-STAR uses a GMSK  (Gaussian Minimum Shift Keying) modulator type  to convert the 8-kHz sampled audio into a 3600-bps bit stream for D-STAR voice. – This stream is combined with the 1200-bps data stream to produce the combined voice+data DV signal at 4800 bps.

[Note] !! The FDMA C4FM (4-Level FSK) is a Frequency Division Multiple Access (FDMA) methodology whereby one user accesses a channel frequency at any one point in time. (i.e. accesses via the frequency domain)…  like NEXEDGE™ Kenwood’s Digital or dPMR and like IDAS™  Icom’s Digital or dPMR radios!

HF-7070 article emphasis the need for a very good phase noise local oscillator! –
n excellent article in the July/August issue of QEX entitled “The HF7070 HF/LF Communications Receiver Prototype” by Colin Horrabin, G3SBI. –
It is a up-conversion design, a double conversion Superheterodyne with a first IF at 45 MHz and a second IF that is centered at 44 kHz before going to a 25 bit audio ADC. – HF-7070 prototype (see QEX) dynamic range rivalling current down conversion big receivers! ..The “in-band” IP3 dynamic range at a 100 Hz spacing in a 2.4 kHz bandwidth is 97 dB ! (…NF 12 dB and an IP3 of 19 dBm)

H, un interessante documento in .PDF con tutti i risultati delle ampie misure (in 20m) fatte in Maggio e Giugno 2013 da NCØB, Rob Sherwood sul TS-990S  Serial #B3300174 (link below!) – Molte misure DR3  (Pre- ON /OFF e 500Hz BW or 250Hz BW) con offset di 5 e 2 kHz sono annotate da Rob con: # Combination of phase noise and 3rd order product / * Consisted of phase noise only ! – Seguono qui alcune note a proposito di misure RMDR o no, tratte dalla più ampia Relazione CTU 2013:

CTU-2013_NC0B RMDR_04 RMDR_08


NCØB, Rob per il TS-990S Ful Test Report, utilizza ben 6 pagine di cui tre per ampie annotazioni sulle misure e sulle anomalie o differenze con standard utilizzabili o utilizzati dalla ARRL, in particolare con Analizzatori con filtri da 3Hz a 1Hz o meno di 1Hz ! – (DR3 with 3 Hz or less testing method)! – Dice non sono condizioni di operazioni reali in aria! Insiste nel valutare (come dice anche Adam, VA7OJ) il valore del fattore di Reciprocal Mixing Dynamic Range (RMDR) – is ofthen the limiting factor in receiver performance! – (RMDR a 5 or 2 kHz è anche ben descritto su QST di Aprile 2012 da Bob Allison, ingegnere ARRL laboratory.

TS-990S #6 REJECTING INTERFERENCE – “IF BEF Filter” & more news



The Kenwood Band Elimination Filter is the notch filter that can change the bandwidth and attenuation (deep) at the IF stage. (See pictur below – click to enlarg!)
Il filtro BEF di eliminazione banda è un filtro notch in cui si può modificare la larghezza di banda (da 300 a 1200Hz) e il picco di attenuazione in fase IF (da -20 a -80dB).- Premere [BEF/SEL] (Main) o [BEF/SEL] (Sub) per abilitare il filtro eliminazione banda IF per il VFO selezionato. Ruotare il controllo NOTCH (M) o NOTCH (S) per regolare la frequenza del notch. (Vedere sul Manuale Utente Kenwood più dettagli!)


The stopband width can be selected from the available range of 300Hz to 1200Hz  and the amount of  attenuation depth can be selected from the available range of 20 dB to 80 dB – The [BEF/SEL] (Main) LED or [BEF/SEL] (Sub) LED lights green / Rotate the NOTCH (Main) or NOTCH (Sub) control to adjust the notch frequency …. (See the Kenwood User Manual for more!)

Kenwood TS-990S – the RF front-end contains selectable Band-pass Filters (covered by the screen on the picture) – The double balanced grounded switch type 1st mixer works by the principle of reduces signal distorsion. – The five built-in 1st IF Roofing filters ahead of the 1st IF stage to eliminate overloading caused by strong signals just outside the fixed bandpass filters or of the Preselector manually adjustable –

Kenwood’s Preselector [P-SEL] selecting the narrow bandwidth tunable filter attenuates the interfering signal which has 2 to 3 MHz separation from the target frequency. –
Icom IC-7700 uses a duble conversion system composed of a D-MOS FET 1st mixer and Icom’s developed image rejection mixer for the 2nd stage and fixed bandpass filters  and a Icom’s [DIGI-SE] preselector type –  ( note the large toroidal coils on the  Icom RF BPF bank)!
