|Battery-Powered Field Operation
The bottom side of the FT-897 contains a “power source tray” which can accommodate up to two of the optional 13.2 Volt, 4500 mAh FNB-78 Ni-MH Battery Packs, for completely portable operation without any external power source. Maximum power output is 20 Watts (all bands) during battery operation, and with two FNB-78s you may expect up to eight hours of operating time (TX 5%, RX 5%, standby 90%). What’s more, you can charge one of the FNB-78 Battery Packs while operating the FT-897 off the other pack—ideal for situations where solar or other power sources are available.
The optional CD-24 Charge Adapter provides the necessary voltage for charging, and it may be used in conjunction with an external 13.8 Volt source, or the optional PA-26 AC Adapter may be used to power the CD-24.
DC 13.8V Mobile Operation
Mobile operation, using the FT-897 as the cornerstone, is pure joy! The combination of the FT-897 and the ATAS-120 Auto-Tune Antenna System provides automated operation from HF through the UHF spectrum!
Using an external 13.8 Volt power source, you get a full 100 Watts of power output on HF and six meters (144 MHz: 50 W, 430 MHz: 20 W).
Base Station Operation
The FT-897’s outstanding fundamental performance invites expansion into a full-featured base station. The optional FP-30 Internal Power Supply provides operation from AC sources, and the clamp-on FC-30 Automatic Antenna Tuner option expands the impedance range of the transceiver. Round out your station with the MD-200A8X Deluxe Desk Microphone and the VL-1000 Quadra System Linear Amplifier for world-class performance at home!
The power source tray of the FT-897 is designed to accommodate the optional FP-30 Internal Power Supply, allowing full-power operation from 100-120 V or 200-240 V AC power sources. The quiet switching-regulator design of the FP-30 is tolerant of AC input voltage variations, making it ideal for DX-pedition use! And to extend the impedance bandwidth of your antenna system, the innovative FC-30 Automatic Antenna Tuner option clamps onto the left side of the FT-897 in seconds!
Rugged, High-Output Power Amplifier
Achieving 100 Watts of power output from such a compact package is a difficult mechanical and electrical engineering task. On HF, push-pull 2SC5125 Bipolar transistors driven by push-pull 2SK2975s provide the 100-Watt power capability, while on VHF maximum efficiency during battery operation is yielded by 2SC3102 bipolar PA transistors. The rugged aluminum 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 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!
Built-in Digital Signal Processing
The FT-897 includes a wide array of analog 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. DSP Bandpass Filters, Noise Reduction,a nd Auto-Notch Filter circuits are included.
Outstanding Features for the CW Expert
A wide array of features are tailored to the CW enthusiast operating from home or on an expedition!
Included are a CW Tuning indicator, CW Pitch control, Electronic Keyer with three memories and Weight Control, and selection of Full QSK or “Semi-break-in” operation.
For DX-pedition use, a unique “Beacon” mode allows you to send a repetitive message on, for example, six meters, to help others spot propagation to your location.
