TS-590S CONTENTS I At the end of September , 2010, the TS -590S, a Kenwood HF band amate ur radio transceiver was launched af ter the 7-year lon g silence since the rele asing of TS-480S . As implied by this mode l name, TS-590S is the “legitimate successor to the TS-570S”.
II CONTENTS TS-590S TS-590S was planned as th e “legitimate successor t o the TS-570S” after 14 years or more of time have elap sed since the first market appe arance of TS-57 0S in 1996. TS-590 S is titled with the 500s model number wit h the TS-570S but, nee dless to say , we started the development as a t otally new transceiver .
TS-590S CONTENTS 1 1 RECEPTION Receive performance is o ne of the key indicators th at 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 4 CONTENTS TS-590S The receiver mixer circuit is a quad mixer consisting of fou r 2SK1740 JFET s. The mixer circuit achieves superio r characteristics th anks to the revision of I/O port matching and the optimizati on of biases. With the signal provide d by the first local oscillator , the RX sign al is converted to 1 1.

4 DSP TS-590S CONTENTS 25 The manual notch filter is a notch filter with a freq uency tha t can be shifted with the notch knob. Th e 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 atte nuation of more than 60 dB at the center fre quency .

4 DSP TS-590S CONTENTS 29 Beat cancel (BC), as it s name implies, is d esigned to cancel unpleasant beat interference. Like NR1 (line enhancer), BC uses adaptive filter technology . With this technology BC tracks and cancels a beat signal just like sha ping a band eliminatio n 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.

In such a case, by using other method s such as noise redu ction in conjun ction, the reception cond itions may be improved.
4 DSP 32 CONTENTS TS-590S Unlike the conv entional noise reduct ion methods, the spectral subtractio n method of NR1 is a brand new approach of no ise reduction de veloped for the TS-590S.

4 DSP TS-590S CONTENTS 35 NR2 is what is known as SP AC. It detects peri odic signals co ntai ned in the RX signal and pieces together the d etected perio dic signals to pr oduce output receive audio. As a result, onl y the periodic signals in the re ceive audio emer ge clearly .
4 DSP 36 CONTENTS TS-590S Figure 4-19 NR2: Active TS-590S also incorporate s an AF-type sp eech processor . Thou gh it is an AF type, th e speech processor provides sufficient compression through a unique sig nal processing technique.
