Features
Top in its class with three dynamic ranges.
Alive and well, the non-tiring KENWOOD tone keeps you listening.
Receive performance on a whole other level from narrow bandwidth roofing filters that only full down conversion can provide
The TS-890S uses 8.248MHz 1st IF frequency down conversion for its receive signal system in order to continue the adjacent interference signal exclusion legacy refined in the TS-990S. This means you can use narrow bandwidth crystal filters with passband widths of 500Hz or 270Hz (optional YG-82CN-1) as roofing filters to achieve strong exclusion of unnecessary adjacent signals. The 1st mixer is the H-mode mixer also carried by the TS-990S. Conversion characteristics have been improved with fine-tuning of input/output matching as well the device used.

High-speed scanning with independent band scope receiver
The configuration of the band scope receiver has changed from the superheterodyne system used in the TS-990S to 1st IF sampling using an A/D converter (14bit/39MHz), and FPGA digital down conversion. This means a change in scanning method from step FFT to FFT, achieving highspeed updates to the display irrespective of span settings.
Local oscillator realizes superior C/N
Interference signal exclusion is not determined by roofing filters and signal system devices alone. The TS-890S has taken the VCO division of the TS-990S and developed it further, combining a VCO device with high C/N in the gigahertz band and a reference oscillation circuit with superior adjacent C/N to deliver C/N characteristics unattainable in conventional units.
1st Local OSC Phase Noise (14.1MHz)
・Values are measured examples.
The speed and quality of KENWOOD’s renowned IF AGC control
A variety of functions are realized through 32-bit floating-point DSP technology inherited from the TS-990S, including modulation/demodulation in all modes, IF filter, IF-AGC, and removal of interfering signals. Popular for its non-tiring and great-quality audio, the IF-AGC has undergone a facelift with a combination of roofing filters and IF filters, and has been designed to enable optimal control under various noise circumstances.

*1 60 m band: Refer to applicable Amateur Radio regulations to your country.
Electronic specifications apply only to amateur bands. Receive sensitivity drops in the vicinity of the 1st IF frequency (8.248MHz) due to IF trapping.
Internal beat may occur during amateur band receive. Band scope (waterfall) screen may also display spurious signals other than receive signal.
