*Kenwood SKY COMMAND SYSTEM II uses a pair of TH-D72A/TM-D710A
transceivers.
TS-990S is limited to the following functions in the operation of the current KSS.
Operation Commander [A / B] in the TS-990S is equivalent to [M / S].
Memory channel is simplex operation only.
Remote power On/Off is not available on Standby State Low Power
Consumption mode.
Control to the main band operation only.
Note: Refer to applicable Amateur Radio regulations to check whether you are
permitted to use this function.
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 access 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.
The dedicated sub-receiver has extensive interfer-
ence elimination capability and is conveniently
located to the right side of the main panel. Access
the knobs and keys you need without hesitation.
Share the use of main and sub band variable encod-
ers by switching the operations object. An LED is lit
when operating the sub band to prevent accidental
operation (this can also be dedicated to the main
encoder variable bandwidth). Other functions have
been significantly upgraded in the TS-990S from
the TS-590S, including band elimination filters,
APF, mute, the addition of slope switching in the
DSP IF FILTER, independent AGC OFF key, and
simultaneous use of NB1/NB2.
Conveniently located interference
elimination controls of the sub-receiver
Frequently used functions are centrally placed in the
immediate vicinity of the main and sub band knob.
Supporting quick operation for radio sporting.
Useful functions positioned around
the main and sub band knob
We equipped the front panel with two USB ports,
a key jack, microphone jack and a headphone jack.
Use USB memory or
a keyboard.
Increased user-friendliness by placing
two USB ports on the front panel
Switch to update mode and insert USB memory into
the USB-A port on the front panel, and the update
will automatically begin. Or access your USB mem-
ory from your PC by connecting your PC via USB
cable to the USB-B port on the rear panel, switch
to update mode, and a folder named TS-990 will
appear on your computer.
Firmware updates by USB
There are a variety of I/O interfaces, including the
microphone jack, analog audio input and output,
USB audio interface, and optical digital interface.
By combining DATA mode (1-3) with SSB/FM/AM
modes, it is possible to easily switch between an
external device for modulation and demodulation.
Switch between DATA VOX function and mute for
each modulated line.
DATA mode supported by
external I/O switching
