Kenwood TS-990SHF Firmware updates by USB flash drive or USB cable, Kenwood SKY Command System

Centrally Located Extensive inter- ference elimination sub-Receiver

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 significantly up- graded 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.

In addition, access your USB memory 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, 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.
