TS-590S CONTENTS I At the end of September , 2010 , the TS-590S, a Kenwo od HF band amateur radio transc eiver was launched af ter the 7-year l ong silence since the re leasing of TS-480S . As implied by this mode l name, TS-590S is the “legitim ate successor to the TS-570S”.
II CONTENTS TS-590S TS-590S was planned as the “legitimate successor t o the TS-570S” a fter 14 years or more of time have elap sed since the first market appe arance of TS-57 0S in 1996. TS-590S is ti tled with the 50 0s model number wit h the TS-570S bu t, needless to say , we started the developmen t as a totally new transceiver .
TS-590S CONTENTS 1 1 RECEPTION Receive performance is one of the key ind icators that is used to evaluate a transceiver . And , above all, the cap ability to protect agains t interference fr om adjacent signals close to the target signal is of the utmost importance.
1 RECEPTION 2 CONTENTS TS-590S Figure 1-1 Dual-m ode Conversion Freq uency Configuration First, let us begin with expla nation about the up-c onversion p ath. In the up-conver sion p ath, double-hea ded arrows are shown at each st age pointing in both directions.
1 RECEPTION TS-590S CONTENTS 3 Figure 1-2 Block diagram: Down Conversion Figure 1-2 describes the circu it configurat ion ar ound the first mixer of the do wn-conversion path, showing the relatio nship s between frequencie s upon receipt of a 14 MHz signal.
1 RECEPTION 4 CONTENTS TS-590S The receiver mixer circuit is a quad mixer consisting of four 2SK1740 JFET s. The mixer circuit achieves superio r characteristics th anks to the revision of I/O port matching and th e optimiza tion of biases . With the signal provi ded by the first local oscillato r , the RX sign al is converted to 1 1.
1 RECEPTION TS-590S CONTENTS 5 • Durin g the transmi ssion: The up-conversion conf iguration is always u sed in all modes and bandwidths. During th e transmission in SS B mode, the p ass bandwid th is determ ined by the filter settin gs (digital filter of the DSP) selected in the menu mod e.

1 RECEPTION TS-590S CONTENTS 7 Measurement Conditions: The abscissa axis shows the distance from the int erfering signal. For ex ample, it repre sents that at the point of 10 kHz the re ceive freque ncy is 14.200 MHz and two inte rfering signal s of 14.
1 RECEPTION 8 CONTENTS TS-590S Difference of characteristics due to th e pass bandwidth in the roofing filter can be viewed in graphs in Figure 1-5 and Figure 1-6. So , let’ s see the char acteristics of the u p-conversion sy stem in which the same front end configurati on is used as previou s models.
1 RECEPTION TS-590S CONTENTS 9 T ypical built-in RX auxi liary circuit s include the va riable pass bandwidth circuit, notch filter and noise blanker (NB). In modern HF transceivers, most of these auxiliar y circuits (=auxiliary functions) are made possible by an arithmetic proc ess of the DS P .

4 DSP TS-590S CONTENTS 21 As for ADCs and DACs, the best combin ation of models are sele cted to suit the type of si gnal processed, especially f or the IF input se ction, high-perfo rmance ADCs de signed for high-e nd audio with dynami c range of 1 14 dB are used.
4 DSP 22 CONTENTS TS-590S Figure 4-3 Control Block Diagram of IF-AGC In the attack control circuit, in addition to the n ormal fast gain shift function , we have added a technology to cap ture the signal trans formation in an overs hoot form and to apply mo derate gain to the signal in order to le ssen the audible clicks.
4 DSP TS-590S CONTENTS 23 TS-590S also incorp orates rich an d powerful interference elimination functions that work within the IF-AGC loop (Figure 4-3).

4 DSP TS-590S CONTENTS 25 The manual notch filter is a notch filter with a freq uency that can be sh ifted with the no tch knob. The auto notch fil ter is a notch filter tha t automatical ly tracks a beat frequency with an adaptive filter technique. Bo th notch filter s have the a ttenuation of more than 60 dB at the center frequenc y .
4 DSP 26 CONTENTS TS-590S There are two setting s on the manual notch filter: Normal and Wi de. Y ou can choose one of two bandwid ths for the notch filte r (Figure 4-8).
4 DSP TS-590S CONTENTS 27 For the demodulation o f the RX signal in SSB, CW , FSK and SSB-DA T A modes, we have em ployed the proven PSN (Phase Sh ift Network) design again.
4 DSP 28 CONTENTS TS-590S Following is how t he TX signal is processed. The audio signal cap tured from the m icrophone or an external terminal is first processed by the b andwidth -limiting filter , .
4 DSP TS-590S CONTENTS 29 Beat cancel (BC), as it s name implie s, is designed to cancel unpleasant beat interference. Like N R1 (line enhancer), BC uses adaptive filter technology . With this technology BC tracks and cancels a beat signal just like shaping a band elimin ation filter .
4 DSP 30 CONTENTS TS-590S Figure 4-10 shows how BC cancels beat signals, as monitored by an FFT analyzer . Notice how multiple beat s are clearly removed by BC.
4 DSP TS-590S CONTENTS 31 Figure 4-1 1 NB2: Inactive Figure 4-12 NB2: Active However , depending on the nature of the pulse noise, the noise blan ker cannot suppr ess the noise effe ctively . In such a case, by using other meth ods such as noise re duction in conj unction, the reception cond itions may be impro ved.
4 DSP 32 CONTENTS TS-590S Unlike the conven tional noise reduct ion methods, the spectral subtract ion method of NR 1 is a brand new approach of noise reduction de veloped for the TS-590 S.

4 DSP 34 CONTENTS TS-590S As a noise suppre ssion process, th e line enhancer method based on a DSP ha s been adopte d by many amateu r radio transce ivers in recent years.
4 DSP TS-590S CONTENTS 35 NR2 is what is known as SP AC. It detect s periodic signals cont ained in th e RX signal and piec es together the d etected peri odic signals to p roduce outpu t receive audi o. As a result, o nly the peri odic signals in the rece ive audio emerge clearly .
4 DSP 36 CONTENTS TS-590S Figure 4-19 NR2: Active TS-590S also incorporate s an AF-type sp eech processor . Th ough it is an AF t ype, the speech processor provides sufficient compression through a uniq ue signal processing technique.
4 DSP TS-590S CONTENTS 37 Figure 4-20 show s how the wavefo rm changes when the sp eech processo r is toggled betw een active and inacti ve. Y ou ca n see that wh en the speech pro cessor is act ivated, the differences in amplitude are averaged and the talk power is increased.

5 SOFTW ARE: ENHANCING OPERA TING PLEASURE TS-590S CONTENTS 41 Just like the TS-480 S, TS-590S employs d ouble fu nction keys to activate differ ent functions by holding down a key . This is meant to make operatio n easier th an in the sy stem requiring one to push a function key first before hitting another key to in voke the desired fu nction.
