Kenwood TS-990S manual Firmware updates by USB, Data mode supported by external I/O switching

HF/50MHz TRANSCEIVER TS-990S Useful functions

Conveniently located interference elimination controls of the sub-receiver

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.

Sub-receiver with extensive interference elimination controls centered on the right side of the main panel.

Useful functions positioned around the main and sub band knob

Frequently used functions are centrally placed in the immediate vicinity of the main and sub band knob. Supporting quick operation for radio sporting.

FIL/SEL:

Preset the bandpass with 2 or 3 widths of the DSP IF filter for quick WIDE/NAR switching operations.

CW T (CW Tune):

Automatic tuning makes the target signal turn into pitch frequency at a press of the CW signal key.

Increased user-friendliness by placing two USB ports on the front panel

We equipped the front panel with two USB ports, a key jack, microphone jack and a headphone jack. Use USB memory or

a keyboard.

Firmware updates by USB

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.

DATA mode supported by external I/O switching

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.
