    Some of the features that are newly added to or improved on the TS-590SG (please refer to the major modifications from TS-590S to TS-590SG in this manual for a list of these features) are also available for free to existing TS-590S users. To do so, download the TS-590S Ver.2 Update .

  • Page 6: Appearance / Mechanism

    GETTING STARTED Appearance / Mechanism • The appearance has been modified to adopt a finishing similar to that of the TS-990S, such as the paint for the upper and lower cases, the color and contrast of the paint and print of the front panel keys, the color of the knobs, and the color and surface finishing of the main dial.

  • Page 7: Reception

    However, there was a big challenge to be solved. When it comes to the pass bandwidth of a roofing filter, at a frequency as high as 73 MHz, which is KENWOOD s mainstream first IF frequency, it is difficult to mass-produce filters with bandwidth as narrow as 500 Hz. To solve this problem, there was no other choice but to lower the first IF frequency.
  • Page 8 01 RECEPTION Figure 1-1 Dual-mode Conversion Frequency Configuration First, let us begin with explanation about the up-conversion path. In the up-conversion path, double-headed arrows are shown at each stage pointing in both directions. This means a transmit signal as well as a receive signal is processed in the up-conversion path. The circuit configuration is a triple-conversion design featuring an IF DSP, a typical configuration for an HF transceiver.

  • Page 9: Down Conversion

    RECEPTION 01 1.2 Down Conversion Figure 1-2 Down Conversion Block Diagram Figure 1-2 describes the circuit configuration around the first mixer of the down-conversion path, showing the relationships between frequencies upon receipt of a 14 MHz signal. The signal from the antenna passes the RF BPF or LPF (as a receive as a receive filter, it divides the frequency band of 30 kHz to 60 MHz into 12 ranges) and RF Amp (or bypasses it) to be sent into the first mixer.
  • Page 10 01 RECEPTION The receiver mixer circuit is a quad mixer consisting of four 2SK1740 JFETs. The mixer circuit achieves superior characteristics thanks to the revision of I/O port matching and the optimization of biases. With the signal provided by the first local oscillator, the RX signal is converted to 11.374 MHz (first IF frequency).
  • Page 11 5 kHz/ FM Hints and Tips ● Is KENWOOD s AM bandwidth narrow? The AM passband width is indicated as 5 kHz for HI CUT, and there were questions asking if this can be widened further. The frequency displayed here is the frequency of the audio bandwidth after demodulation. At the IF stage, therefore, the passband is twice as wide at the upper and lower bands, and the IF passband width is indicated as 10 kHz.
  • Page 12 01 RECEPTION Following is a graph that provides the comparison between the performances of roofing filters. Figure 1-5 Comparison of Bandpass Characteristics of MCFs Figure 1-5 compares the band pass characteristics of a roofing filter of center frequency 73 MHz (gray line); and the roofing filters of the center frequency 11.374 MHz with bandwidth of 500 Hz (blue line) and with bandwidth of 2.7 kHz (orange line) that are both employed by the TS-590S.
  • Page 13 Meanwhile, difference is observed between the TS-590SG and TS-590S particularly when it is close to the receive signal at 2 kHz. This is due to influence from the NB filter immediately after the first mixer. On the TS-590SG, the signal passes through the NB filter when the NB is OFF, enabling the full performance of the roofing filter.

  • Page 14: Up-Conversion

    01 RECEPTION 1.3 Up-Conversion Difference of characteristics due to the pass bandwidth in the roofing filter can be viewed in graphs in Figure 1-5 and Figure 1-6. So, let s see the characteristics of the up-conversion system in which the same front end configuration is used as previous models.
  • Page 15 RECEPTION 01 Noise is typically pulse-shaped and when the noise passes a narrow filter, the pulse waveform is changed to have a wider (longer) pulse width. Within the DSP, the processing block of the noise blanker is placed in a stage earlier than the filter block that determines the final pass bandwidth.

    TRANSMISSION 02 2.4 DRV Terminal The TS-590SG is equipped with a DRV terminal formerly available only on high-end transceivers. It is capable of signal output prior to amplification to 100 W at the final unit. The output level of the signal from this terminal is too low to be transmitted as is, but by connecting a high-gain linear amplifier, the signal can be used for operation in the 135 kHz or 475 kHz band, or for operation with a transverter.

    03 LOCAL OSCILLATOR In the first local oscillator, instead of employing the usual PLL/VCO system, the output of a DDS (Direct Digital Synthesizer) is supplied directly to the mixer. As the oscillator frequency during down conversion is lower than it is during up-conversion, better C/N characteristics can be obtained.

  • Page 27: Advanced Agc Control Via If Digital Processing

    Through repeated innovations while inheriting the tradition, the IF-AGC process can be regarded as the evolution of the "KENWOOD Tone". TS-590SG has adopted a sophisticated frequency configuration to switch between down conversion and up-conversion depending on the conditions. The IF-AGC process is designed in such a way that interfering signals do not affect the target signals even though the passband width may be widened at the stage before the final passband width of DSP (analog stage).

    Generally, the amount of delay is significant for such narrow-bandwidth filters, which may be attributable to ringing in the case of combination with an IF-AGC with high-speed response characteristics. For the TS-590SG, ringing is minimized as much as possible to reduce the overall delay of the filter.

  • Page 31: Manual Notch Filter And Auto Notch Filter

    DSP 04 4.3.3 Manual Notch Filter and Auto Notch Filter The manual notch filter is a notch filter with a frequency that can be shifted with the notch knob. The auto notch filter is a notch filter that automatically tracks a beat frequency with an adaptive filter technique. Both notch filters have the attenuation of more than 60 dB at the center frequency.

  • Page 32: Noise Blanker (Nb2)

    ● What is a auto notch filter? The "auto notch filter" from KENWOOD processes the signal at the IF stage. In other words, it is the IF auto notch filter. And the notch filters that process the signal at the AF stage are known as "Beat Cancel (BC1, BC2)".

  • Page 33: Demodulation

    DSP 04 4.4 Demodulation For the demodulation of the RX signal in SSB, CW, FSK and SSB-DATA modes, we have employed the proven PSN (Phase Shift Network) design again. In the previous models (TS-2000/X and TS-870S), the selection of the PSN s characteristics was interlocked with the passband setting of the IF filter, and when the passband is narrow, a PSN with a good sideband suppression was selected.

  • Page 34: Modulation

    04 DSP 4.5 Modulation Following is how the TX signal is processed. The audio signal captured from the microphone or an external terminal is first processed by the bandwidth-limiting filter, microphone gain control, speech processor or VOX, and then, in SSB and AM modes, the signal is modulated and output as an IF signal;...

  • Page 35: Dsp-Based Auxiliary Circuits (For Rx)

    DSP 04 4.6 DSP-based Auxiliary Circuits (for RX) 4.6.1 Beat Cancel (AF Processing) Beat cancel (BC), as its name implies, is designed 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 shaping a band elimination filter. BC is especially effective when there are multiple beats that are equivalent to or lower in strength than the target signal.

  • Page 36: Noise Blanker Nb2 (If Processing)

    04 DSP Figure 4-11 shows how BC cancels beat signals, as monitored by an FFT analyzer. Notice how multiple beats are clearly removed by BC. There are two methods available for beat cancellation: BC1 and BC2. BC1 is tuned to be effective against weak or continuous beat interference, while BC2 cancels intermittent beats such as a CW signal.

In such a case, by using other methods such as noise reduction in conjunction, the reception conditions may be improved. Hints and Tips ●...

  • Page 38: Overview Of Noise Reduction

    04 DSP Thus, NB2 is also effective for pulse noise that NB1 has no effect on, and causes very little unnaturalness in the auditory sense as the target signals are not truncated. Also, unlike the NB2 of the analog era, it is not intended for a specific pulse cycle. Meanwhile, however, when there are strong target signals, pulse sound may be heard, as differences in the amplitude of the pulse noise is detected and attenuated to the level of the target signal.

  • Page 39: Nr1 (Based On A Line Enhancer) (Af Processing)

    DSP 04 The new spectral subtraction-based NR1 allows selection of the NR effect level more smoothly than the conventional NR1 method. Use the effect level of your choice according to the receive conditions. Note, however, since the noise estimation process of the spectral subtraction NR1 identifies any steady sound as a noise component, beat interference or a CW signal is also judged as a target of noise reduction.

  • Page 40: Nr2 (Af Processing)

    04 DSP 4.6.6 NR2 (AF Processing) NR2 is what is known as SPAC. It detects periodic signals contained in the RX signal and pieces together the detected periodic signals to produce output receive audio. As a result, only the periodic signals in the receive audio emerge clearly. NR1 based on an NR1 line enhancer is a filter in essence, but NR2 processes a RX signal in a different approach.

    DSP 04 4.7 DSP-based Auxiliary Circuits (for TX) 4.7.1 Speech Processor (AF Processing) TS-590S/SG also incorporates an AF-type speech processor. Though it is an AF type, the speech processor provides sufficient compression through a unique signal processing technique. A typical voice signal tends to have the highest amplitude in the low frequency range with smaller amplitude as the frequency range increases.

    The PC command TX1; is used for transmitting the external input audio using the PC controller. Furthermore, TS-590SG can transmit the external input audio according to the SEND/PTT or SS signal during DATA mode. Setting the SOURCE OF SEND/PTT TRANSMISSION in Menu 70 to REAR (input connector on the rear panel) switches the transmission source in conjunction with enabling or disabling the DATA mode.

    Also, since the active or inactive state of the DRV is stored for each band, you can interlock the status with the RX ANT connector to handily run a transverter. The DRV connector on TS-590SG can also function as an antenna output terminal for external receivers. (Refer to 01 RECEPTION )

For TS-590SG (TS-590S Ver.2 Update or later), improvements have been made to the storing of the selective states of FILTER A and FILTER B using VFO A and VFO B respectively. This enhances user convenience during split operation; the VFO at the receiving end uses the narrow bandwidth FILTER A to remove the interference and the VFO at the transmitting end uses the wide bandwidth FILTER B to check the signal condition near the transmitting frequency via TF-SET.

    As explained above, TS-590S/SG is designed for heavy-duty operation as were the previous HF transceivers, but, as a general rule not limited to KENWOOD products, the higher the temperature, the shorter the life span of an electronic device. Therefore, we recommend you use the transceiver with an appropriate output power that suits the circumstances in order to prolong the longevity of the transceiver.
