The FT-897D is a rugged, innovative, multiband, multimode portable transceiver for the amateur radio MF/HF/VHF/UHF bands. Providing coverage of the 160-10 meter bands plus the 6 m, 2 m, and 70 cm bands, the FT-897 includes operation on the SSB, CW, AM, FM, and Digital modes, and it's capable of 20-Watt portable operation using internal batteries, or up to 100 Watts when using an external 13.8-volt DC power source.

The rugged aluminium die-cast chassis provides a solid foundation for the heat sink for the power amplifier, with a total of almost 40 cubic inches of heat sink surface area available. With its quiet, thermostatically-controlled twin cooling fans, the FT-897 will stand up to the rigors of DX-pedition or home contest use, with dissipation capability to spare.

When you've travelled a great distance to find that ultimate quiet operating location, you want a great receiver so as to take advantage of it ! Yaesu's top receiver design team crafted the front end of the FT-897, accounting for the dramatic differences between low bands like 160 meters and the 430 MHz microwave band. Wide dynamic range and low noise low noise figure are the product of the advanced preamplifier stage with negative feedback for stability, and the GaAs balanced mixer design, with careful gain distribution from the RF through the audio stages.

Flexibility in strong-signal operation is also provided by the RF Gain control, input attenuator, input preamplifier bypass capability (IPO), and Slow/Fast/Off AGC selections.

The quiet, fast-acting local oscillator system of the FT-897 borrows extensively from the renowned FT-847, using a Direct Digital Synthesizer (DDS) to achieve fast lock times and silky-smooth tuning in 10 Hz steps. The excellent carrier-to-noise ratio helps preserve spurious-free dynamic range in a crowded band, and the smooth tuning leaves you with the feeling you're using an analogue VFO.
The FT-897 includes a wide array of analogue and DSP filters to help you dig out those weak DX signals on a crowded band! One-touch activation of the DSP filters, plus a convenient "DSP" LED on the front panel, enhance the ease of using the DSP
