HF/6m Flagship Base Station

The TS-990S comes equipped with dual receivers for simultaneous dual reception on different bands, it also
features narrow-band roofing filters on the main receiver in a full down-conversion configuration. The TS-990S achieves the highest basic reception performance of any radio in the TS series, through the careful selection of circuits, components and accelerating analysis using triple DSP configuration. The Trio tone has evolved into Kenwood tone. Also, thanks to the dual TFT display and superior panel layout, it achieves both comfortable visibility and operability.

Our top-of-the-line transceiver is for all radio operators who love HF.
