The Kenwood TS-990s HF-Base Station Transceivers. Equipped with dual receivers to enable simultaneous reception on two different bands. The main receiver employs full down-conversion and features a new mixer and narrow-band roofing filters, resulting in a third-order intercept point of +40dBm; this represents the highest level of RX performance. Also equipped are triple 32-bit floating-point DSPs and an original IF AGC circuit featuring leading-edge DSP technology. Advanced KENWOOD technologies deliver the top-end RX performance that DX’ers are looking for in an HF transceiver. Moreover, 50V MOSFETs are used for the final amp, ensuring stable high-output operation with minimal distortion, even at 200W RF output power. All this and more: The world’s first*1 dual TFT display – with a band scope, audio scope, and S meter – offers enhanced visibility and operating ease.
