Kenwood's new masterpiece is an HF / 50MHz / 70MHz.
Equipped with a complete conversion receiver, roofing filters for 500Hz / 2.7kHz / 6kHz / 15kHz and 270Hz option.
A 7-inch color TFT display with full bandwidth.
Output power 100 W on HF / 50 MHz, 50 W on 70 MHz ( Europe version only ).
110dB * 3 ° dynamic intermodulation interval (3rd IMDR) measured in punitive 2kHz spacing conditions. 114dB * reciprocal mixing dynamic range (RMDR). 150dB * Dynamic Range Lock (BDR) All functions offer first-class reception performance. The high-performance DSP shows its skill in controlling interference signals, adjusting sound quality and digital operation.
(*: 2 kHz spacing measurement standard - Receiver frequency 14.2 MHz, MODE CW, BW 500 Hz, PRE AMP OFF)
TCXO as standard, high frequency stability at ± 0.1 ppm
TCXO temperature drift characteristics
- Values are measured examples.
Equipped with a TCXO (temperature compensated crystal oscillator) that does not require standard heating, a high stability of ± 0.1 ppm has been obtained in a wide temperature range covering from 0 ° C to + 50 ° C. It is also possible to input the external standard signal (10 MHz).
A variety of functions allows you to quickly perform split operations even with a single receiver. Rapid split frequency settings, switching of the status band divided by a direct band key and support for external TF clock via an external receiver. A panel layout that allows intuitive management facilitates operation.
- Split frequency settings
In addition to the conventional split frequency setting methods, the TS-990S's proven split setup functions have been included. For 2kHz SU, press "2" on the numeric keypad after a long press of the SPLIT button and the settings are complete. The divided frequencies can be set within a range of ± 9kHz (1kHz steps).
By connecting another TS-890S or TS-590S / SG * 1 unit to the ANT OUT connector to be used as a sub-receiver * 2 and using the split A transfer function, this can enable assistance in simultaneous 2-wave reception during the split operation * 3.
* 2: a loss of about 3dB (theoretical value) is detected
* 3: frequency transfer, standby mode and secondary audio muting are possible. Requires separate antenna cable and RS-232C crossover cable. Not compatible with combined SP / headphone use.
The unit is compatible with the encoding / encoding of the CW Morse code. Morse code transmission is possible with text input from a USB keyboard. The combined use of models sent from message memories and Morse code transmissions via the panel is also possible. Switching of the dedicated decoding filter and functions for transmission registers and output of decoded text on PC are also included.
- Basic RTTY operating settings (insertion polarity, displacement width, HI / LO tones, reverse mode) - Compatible with PSK31 (QPSK, BPSK) and PSK63 (BPSK) - RTTY / PSK operation via integrated decoder / encoder (keyboard USB compatible) - Message memory function - Display of the regulation spectrum (FFT audio, cascade / XY range (FSK) / vector range (PSK)
When using the KNS (KENWOOD Network Command System), remote radio operation is possible via a direct LAN connection. Conventional connection is also possible using a host PC and ARHP (Amateur Radio Host Program).
The TS-890S has a 1 GB internal memory and can record a maximum of about 9 hours of audio without using the USB memory *. When using USB memory, depending on the capacity, there is no limit on the amount of audio recording. Recording options include normal, constant and timer, and recording can also be linked to the squelch.
*: Other files that share memory capacity can result in less than 9 hours.
