Delivering the ultimate in split-operation operability.
An interface that thinks of everything.

Stronger split-operation handling through VFOA/B

● Split frequency settings

In addition to conventional split frequency setting methods, the TS-990S’s proven split setting functions have been included. For 2kHz UP, press ‘2’ on the number pad after a long press of the SPLIT key and the settings are complete. Split frequencies can be set within the range of ±9kHz (1kHz steps).

Band direct key

● Band changing possible while keeping split settings for each band (menu setting feature)

In the split state, changing the band or band memory via the band direct key will make changes while keeping the split state. Individual settings are possible for the split frequencies and modes for each band memory, which is convenient for chasing DX-peditions during multiband/mode operation.

● Split frequency changing (menu setting feature)

In addition to the conventional method of operating the tuning knob during TF-SET, when RIT/XIT is not in use, the split frequency can also be changed by operating the RIT/XIT knob.

● Split frequency receive via external receiver (menu setting feature)

By connecting another TS-890S or TS-590S/SG*1 unit to the ANT OUT connector to use as a sub- receiver*2 and using the split transfer function A, this can enable assistance in 2-wave simultaneous receive during split operation *3.

  • *1: Requires a firmware update.
  • *2: Loss of approximately 3dB (theoretical value) is experienced
  • *3: Frequency transfer, standby, and sub- receiver audio mute are possible. Requires separate antenna cable and RS-232C cross-cable. Not compatible with combined SP/headphone use.

● IF filter A /B/C one-touch switching

Three kinds of bandwidth presets and instantaneous switching are possible for IF filters. Switching can also be limited to 2 kinds, so this enables use for wide/ narrow switching. Using the FIL.CLR key, a changed bandwidth can be returned to a preset frequency with a single touch.

CW Morse code decode/encode possible with stand-alone unit

The unit is compatible with CW Morse code decode/encode. Transmission of Morse code is possible with text input from a USB keyboard. Combined use of templates sent from message memories and Morse code transmissions via panel is also possible. Dedicated decode filter switching, and functions for transmission logs and output of decoded text to PC are also included.

FSK/PSK functions

  • ● RTTY basic operation settings (keying polarity, shift width, HI/LO tones, reverse mode)
  • ● Compatible with PSK31 (QPSK, BPSK) and PSK63 (BPSK)
  • ● RTTY/PSK operation via on-board decoder/encoder (USB keyboard compliant)
  • ● Message memory function
  • ● Tuning scope display (audio FFT, waterfall/X-Y scope (FSK)/vector scope (PSK))

Compatible with FM operation on 28MHz, 50MHz bands

The unit includes switching to FM narrow for transmit and receive, as well as repeater operation support and FM signaling functionality (CTCSS, cross-tone).

DATA mode compatible with external input /output switching

Separate from the microphone connector, the back panel includes a variety of I/O interfaces, including analogue audio input and output, USB audio interface, and LAN(VoIP)interface. By combining DATA mode with SSB/FM/AM modes, it is possible to freely set channels for modulation and demodulation. Furthermore, combined use with DATA VOX enables the transmission of modulation signals from a PC, rendering standby wiring and commands unnecessary.

Remote operation achieved without host PC Direct remote-control function (KNS)

When operating using the KNS (KENWOOD Network Command System), remote operation of the radio as possible by a direct LAN connection. Conventional connection using a host PC and ARHP (Amateur Radio Host Program) is also possible.

USB memory / USB cable firmware update function

Starting the unit in update mode and inserting a USB memory stick containing firmware into the front USB-A port will start an automatic update. Updates can also be carried out by connecting the TS-890S to a PC via a USB cable, and moving a firmware file using drag & drop on top of the ‘TS-890S’ removable device that is displayed on the PC’s desktop during update mode.

Recording functions

The TS-890S comes equipped with a 1GB internal memory, and can record a maximum of roughly 9 hours of audio without using USB memory*. When using USB memory, depending on the capacity, there are no limits on the amount of audio recording. Recording options include normal, constant, and timer, and recording can also be linked to the squelch.

  • * Other files sharing memory capacity may result in less than 9 hours.

Diverse functions supporting CW operation

  • ● PADDLE/KEY jack (one each on front/rear, compatible with paddle/ straight key switching)
  • ● CW auto tuning
  • ● Full break-in and semi breakin (semi break-in delay time: 50ms~1000ms)
  • ● CW Pitch control, Side tone (pitch frequency linking 5Hz steps)
  • ● Built-in electronic keyer (key speed settings, keyer mode A/B selection)
  • ● 8CH CW message memory function
  • ● Auto-switch to CW mode on keydown in SSB mode
  • ● Microphone paddle mode
  • ● CW auto wait/wait reverse
  • ● CW reverse mode / CW BFO side band switching


(When connected to TH-D7A*/TH-D72A/TM-D710A*/TM-D710GA)** Enables full-duplex operation with improved functionality such as visual confirmation of HF frequency on the LCD panel. Control via TNC (AX.25) enables more accesses to HF functions: XIT, mode switching, split-frequency operations on/off, memory shift, and frequency step selection. The transporter sends out its pre-programmed call sign via CW every 10 minutes.

  • * Discontinued product
  • ** KENWOOD SKY COMMAND® II uses a pair of TH-D7A*/ TH-D72A / TM-D710A*/TM-D710GA

Note: Refer to applicable Amateur Radio regulations to check whether you are permitted to use this function.
