Transporter Commander
*Kenwood SKY COMMAND SYSTEM II uses a pair of TH-D72E/TM-D710E
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 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.
Centrally Located Extensive inter-
ference elimination sub-Receiver
Frequently used functions are centrally placed in the
immediate vicinity of the main and sub band knob.
Supports quick operations.
Useful functions positioned around
the main and sub band knob
Switch to update mode and insert USB memory into
the USB-A port on the front panel, and the update

switch to update mode, and a folder named TS-990
will appear on your computer.

There are a variety of I/O interfaces, including the
microphone jack, analogue 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.

The PF key default is for voice trans-
mission, but you can also assign a
different function to it.
FIL/SEL:
Preset the bandpass width to 2 types
or 3 types with the DSP IF filter for
quick WIDE/NAR switching operations.
The dedicated sub-receiver with extensive interfer-
ence elimination is centrally located at the right
edge of the main panel. Access the knobs and keys
you need without hesitation. Share the use of main
and sub band variable encoders 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 band-
width). Other functions have been signi cantly up-
graded in the TS-990S from the TS-590S, including
band elimination lters, APF, mute, the addition of
slope switching in the DSP IF FILTER, independent
AGC OFF key, and simultaneous use of NB1/NB2.
Using the ARCP-990 software (radio control soft-
ware), you can control most functions from your PC.
Control the memory channel, settings, and functions
using your PC. Download the free software from the
Kenwood website.
