coverage of all nine HF Amateur bands, plus VHF/UHF coverage of the 50, 144, and 430 MHz bands. The FT-847 Earth Station provides 100 Watts of power output on 160 through 6 meters, and 50 Watts output on 144 MHz and 430 MHz. General-coverage HF receive capability is provided, along with VHF/UHF reception at 37~76 MHz, 108~174 MHz, and 420~512 MHz. Independent antenna ports are provided: one each for HF, 50 MHz, 144 MHz, and 430 MHz. The front panel's multi-function blue display includes dual frequency registers, digital metering, and a wide variety of status displays. The FT-847's compact size makes it ideal either for base station, field day, vacation, or VHF/ UHF "rover" expeditions. Important features of the FT-847 Earth Station include: crossband full duplex capability with normal/inverted tracking for satellite work; built-in low-noise preamplifiers; DSP Noise Reduction, Notch, and Bandpass Filters; AFSK I/O port for teletype, HF packet, AMTOR, or high-speed CW work; 1200/9600 bps packet jack for VHF/ UHF; two tuning knobs plus Shuttle-JogTM dial for easy frequency navigation; direct keyboard frequency entry; Digital Speech Processor; adjustable CW pitch/sidetone; alpha-numeric label tags for labeling satellite memories; built-in CW electronic keyer with weight control; built-in CTCSS/DCS encode-decode operation for FM; and a high-speed (up to 57600 bps) CAT port for external computer control. Available options include Collins® Mechanical IF Filters for SSB and CW, and the FVS-1A Voice Synthesizer for visually impaired operators. Thank you for your investment in the FT-847 Earth Station. We recommend that you read this manual in its entirety as soon as possible, so as to gain a fuller understanding of the many capabilities of your new transceiver.
