    The TS-890S, the latest addition to the glorious history of the TS-800 family, has been developed not only to complement the TS-990S and TS-590 series, but attention has also been devoted to the “basic reception performance”, which is the main interest of our customers.
  • Page 6: Features Of The Ts-890S

    01 prologue As described above, TS-890S has been developed to inherit the DNA of KENWOOD’s HF transceivers and as a model that forms the core of the TS-x90 series. It is an advanced transceiver for practical use that has evolved in its own ways as a full-fledged successor of the TS-800 family, and not just a modified version of the TS-990S or TS-590 models.
  • Page 7: 02 Reception Circuit

    02 RECEPTION CIRCUIT Receiver Configuration The TS-890S is the single-band transmitter-receiver of the down-conversion method, which is refined and diverted from the circuit configuration of the main band receiver of the top-model TS-990S. During transmission, the receiver behavior stops. Also, the bandscope circuit shows the status of IF signals during reception and transmission.
  • Page 8 02 RECEPTION CIRCUIT The received signal which was input from the antenna comes into the front-end block of the receiver through the antenna switching circuit. The bandpass filter for the selected receive band eliminates interfering signals outside the band. The received signal is amplified by a pre-amplifier and is then converted to the first IF signal (8.248 MHz) by the first H-mode mixer having high IP characteristics.
  • Page 9: First Mixer

    RECEPTION CIRCUIT 02 First Mixer For the first mixer, the “H-mode mixer” with less distortion is refined and diverted from the one adapted in the TS-990S main receiver, and the conversion loss has been reduced and matching of the frequency characteristics of the mixer input port by the wide bandwidth is enabled.
  • Page 10: Roofing Filters

    02 RECEPTION CIRCUIT Roofing Filters Four types of roofing filters are equipped as standard as narrowband filters of high IP characteristics implemented by the full down-conversion method. In addition, to meet the needs for narrower band filters, optional filters are available (sold separately) and supported by a mounting slot.
  • Page 11: Agc Circuits

    The AGC circuit is required to have low noise and a wide dynamic range, wide control range, and linearity to the control. The TS-890S implements high-precision AGC response characteristics with the combination of an AGC circuit in which a dual-gate MOSFET is used and the correction process made by DSP. The “AGC Circuit with a Dual-Gate MOSFET”...
  • Page 12: Optimization Of Gain Distribution

    The IARU (International Amateur Radio Union) standard scale requires -73 dBm for S9. However, concerning the S meter needle deflection, on all of the KENWOOD transceivers, it is -81 dBm for S9 in the 14 MHz band while a pre- amplifier is on.
  • Page 13: Noise Level

    RF Gain Adjustment KENWOOD HF-band transceivers are configured with our consistent philosophy to balance the levels, such as the sensitivity, S meter needle deflection, pre-amplifier gain, gain correction, and other factors, thus the internal noise may be conspicuous if the input level from an antenna is low.
  • Page 14: Noise Blankers

    Features of the NB1 and NB2 The TS-890S has two noise blankers; NB1 for analog processing and NB2 for digital processing by DSP. NB1 is effective for short-cycle pulses, such as ignition noise. NB2 is effective for noise that the analog noise blanker (NB1) cannot follow.
  • Page 15: Auxiliary Circuits

    Medium Wave Band Sensitivity Risers Just as in past transceivers, the TS-890S has attenuators of approximately 20 dB for the medium wave band (522 kHz to 1.705 MHz) (as the factory default, the sensitivity is lowered by approximately 20 dB by the attenuators). In the medium wave band, there are a number of strong radio waves and there may be medium wave band signal input that is excessive for low-band antennas.
  • Page 16: 03 Transmission Circuit

    03 TRANSMISSION CIRCUIT IF Circuit for Clean and Stable 100 W Output Power A signal modulated and multifariously processed in the DSP is fed as the 24 kHz (modes other than FM) or 36 kHz (FM mode) transmit first IF signal by a D/A converter, which is then converted by a diode mixer used for both transmission and reception to 8.248 MHz.
  • Page 17: High-Speed Relay-Controlled Antenna Tuner

    Fig. 14 Transmit IMD Characteristics (14.2 MHz, 100 W output power) output power) High-speed Relay-controlled Antenna Tuner The TS-890S has a high-speed relay-controlled antenna tuner, which digitally controls in a combination of capacitors of different capacitance through switching relays. The digital control achieves high-speed tuning.
  • Page 18: Linear Amplifier Control

    03 TRANSMISSION CIRCUIT Linear Amplifier Control Linear amplifier control can be used for switching between transmission and reception of devices such as the linear amplifier and transverter. REMOTE Connector The REMOTE connector is a 7-pin DIN type connector, the same as our conventional transceivers. The LKY (Linear amplifier Keying) terminal (pin 7) is equipped with a logic to output 12 V on transmission and a logic for short-circuiting to ground on transmission according to the linear amplifier menu setting which will be described later.
  • Page 19: Linear Amplifier Menu Settings

    Voltage and current not higher than DC 50 V and 100 mA respectively can be controlled. The TS-890S linear amplifier control relay functions on transmission if “Internal Relay Control” is enabled in the Linear Amplifier Menu. The linear amplifier control relay assumes that the TL-922 (discontinued) is standing by and can be connected as-is to the TL-922.
  • Page 20 03 TRANSMISSION CIRCUIT ● Tx Delay Time (CW/FSK/PSK) For configuring the delay time that is enabled when in the CW/ FSK/PSK non-audio mode. ● Tx Delay Time (SSB/FM/AM) For configuring the delay time that is enabled when in the SSB/FM/AM audio mode. This can be configured to a setting that is different from that for the non-audio modes.
  • Page 21: Alc

    The ALC signal is a signal output from an external device that shifts the voltage to the negative side (for KENWOOD transceivers) when the transmit power reaches the range to be restricted from the external device standpoint. External devices generally have voltage adjustment VRs (variable resistors).
  • Page 22: Transmit Power Limiter

    03 TRANSMISSION CIRCUIT Transmit Power Limiter The transmit power limiter prevents the transmit power from exceeding the pre-configured transmit power level. It can be turned on or off by pressing the F [MAX-Po] key. The power limit can be configured for each band as well as for each of the SSB, CW, FSK/PSK, AM/FM and DATA modes.
  • Page 23: Alc Operation When An External Device Is Connected

    The “Connection Block to an External Device for ALC Signal Input” diagram shows the connection block with an external device when ALC signal is input from the external device to the TS-890S as well as changes in the output level with the ALC voltage.
  • Page 24: Drv Terminal

    03 TRANSMISSION CIRCUIT DRV Terminal The output level from the DRV connector is approximately 0 dBm (1 mW). Power detection is performed for output from the ANT terminal, and the output will not exceed the preconfigured level due to activation of ALC. However, the output level will fluctuate as ALC will not be activated for the DRV terminal output if ALC signal is not input from the external device.
  • Page 25: Protections

    Not only does a high antenna SWR impede efficient radio wave radiation, distortion may occur in the final circuit due to the reflected waves, and the TS-890S or the antennas may be damaged as a result. To prevent such a problem from occurring, a protection circuit is implemented to reduce the transmit power to reflected waves.
  • Page 26: 04 Local Oscillator Circuit

    04 LOCAL OSCILLATOR CIRCUIT Local Oscillator The local oscillator circuit in the TS-890S is configured to obtain the characteristics needed for each signal, such as the VCO (Voltage Controlled Oscillator) division type for the first and second oscillator signals and DDS (Direct Digital Synthesizer) direct system for the third local oscillator.

    Menu [67]: Select 115200 bps Enable the split operation mode on the TS-890S and set VFO A/B. When TX VFO on the TS-890S is altered, the RX frequency on the TS-590G will change automatically. To change the TX frequency on the TS-890S, set XIT to ON and turn the RIT/XIT knob.
  • Page 30 The photo below shows the display screens on the TS-890S and TS-590 with split transfer feature 1 enabled. The quickest way to enter the split operation mode is to long-press the SPLIT button on the TS-890S until the band direct key starts flashing. Next, push the frequency to offset for the transmitting call to enter the split mode for simultaneous reception of two bands.

  • Page 33: 07 Dsp

    We have been providing “Quality” in communications that cannot be realized only by analog circuits. The development concept of the DSP for the TS-890S is the ability of its application to actual operations. It has gone through a thorough brush-up to deliver the best performance under harsh and unfavorable conditions.
  • Page 34: Signal Processing In The If Stage

    Fig. 32 IF Stage Block Diagram AGC loops of the TS-890S are placed before and after the interference rejection, such as an IF filter or notch filter. The AGC loop of the preceding stage functions to prevent signals whose level is higher than the reference from being input to the A/D converter for the IF input and is called the out-band AGC loop.

When pulse noise generated by sources such as an electric fence is received, the in-band AGC attacks the pulse noise to lower the gain of the AGC amplifier.
  • Page 36: If Filter

    07 DSP IF Filter As the main band limitation filter, the TS-890S is equipped with roofing filters for the analog stage as well as DSP digital IF and AF filters (in addition to these, there are also audio peak filters, etc.).
  • Page 37 SSB mode. Employing the digital filter design technology that we have accumulated, the TS-890S now offers a filter and IF-AGC design that minimizes ringing as well as impact on the sound quality. As the roofing filter settings for the analog circuit vary in tandem with the specified filter bandwidth characteristics, interference by adjacent signals is less likely to occur when a narrow band of 500 Hz or lower is configured in the CW mode.
  • Page 38: Interference Rejection

    ● Noise Blankers The TS-890S has two noise blankers, NB1 and NB2. NB1 is the noise blanker for the analog circuit. NB2 is the noise blanker for digital signal processing. NB2 offers two modes, Type A and Type B, which can be employed for different situations.
  • Page 39 DSP 07 NB2 affects the noise that cannot be processed by the analog circuit; however, there may be a case where it cannot suppress the noise depending on the strength of the desired signal and characteristics of the pulse noise. In such a case, by using noise reduction together, the receiving status may be improved.
  • Page 40: Reception

    The optimal design of the PSN system is determined by the characteristics of the IF filter that comes with the transceiver. If a steep and large-attenuation filter similar to the IF filter of the TS-890S is used, the number of reverse bandwidths to be canceled by the PSN system is very small.
  • Page 41: Af Filter

    RX equalizer. Emphasis was also placed on the AF filter design of the TS-890S to process the signal in the stage preceding demodulation in the SSB, CW, FSK and PSK modes.
  • Page 42: Audio Peak Filter

    07 DSP ● AM and FM Modes In the AM mode, the AF filter is placed after demodulation. It adopts a mechanism that switches the IF filter bandwidth when the high-cut frequency is switched. Meanwhile, switching the low-cut frequency alters only the AF filter setting. In the AM mode, extending the bandwidth only with the IF filter may cause the audio to sound distorted.
  • Page 43: Noise Reduction

    The TS-890S employs a technique to reduce musical noise (tonal “blip blip” sound that is minutely segmented) that is inherently generated as a result of the spectral subtraction process. With this technique, musical noise is largely reduced, and influence by digital processing that is incidental to noise reduction is lowered.
  • Page 44 SSB mode. It is positioned in the TS-890S as a noise reduction method for non-audio signals. The graphs below show how NR1 improves the S/N ratio of a tone signal with the line enhancer method.
  • Page 45 DSP 07 ● NR2 (SPAC Method) The NR2 is for noise reduction with a speech processing system by using the Autocorrelation function, which is called SPAC (Speech Processing system by use of the Auto Correlation function). This system enables to detect periodic signals contained in the received signal and to piece together the periodic signals detected as the received signal to be reproduced.
  • Page 46: Beat Canceler

    07 DSP Beat Canceler While the notch filter processes signals in the IF stage, the beat canceler suppresses the beat in the AF stage. Beat canceler is effective when there are multiple beat signals. The beat canceler employs an adaptive filter technique which is of the same type as that for the NR1 line enhancer method.
  • Page 47: Signal Processing By Morse Code Decoder

    DSP 07 Signal Processing by Morse Code Decoder The Morse code decoder is a feature that decodes Morse codes received in the CW mode and displays them as text on the screen. When we first introduced the Morse code decoder, which was on the TS-590G series, there were cases where erroneous decoding results were displayed under certain reception conditions.
  • Page 48: Transmission

    07 DSP On the TS-890S, the processing block has been modified to enable more accurate decoding. Envelope Threshold RX IF IF Filter Limitter Delay Detection Judge Fig. 54 Detection Block of Morse Code Decoder on TS-890S Envelope detection is performed with Morse codes controlled at a constant level via AGC processing. The level assessment by AGC are then synchronized with the threshold assessment of envelope detection to enhance the decoding rate.

    “adjacent signal discriminability (frequency resolution)”, has become an important feature for more practical use of the transceivers. To further enhance the practical use of the bandscope on the TS-890S, we have significantly brushed up both processing of signals from the RF unit as well as the software.
  • Page 54: Reference Level

    ● Center Mode (CENTER MODE) The RX frequency is always fixed at the center of the horizontal axis of the bandscope in this mode. The TS-890S adopts a straight-line waterfall display when the frequency is altered. Changing the frequency displaces the flow of the bright lines that indicate the signal intensity horizontally, and tuning is possible by overlapping it with the RX marker.
