Ultra Compact Design

Measuring just 6.1” x 2” x 9.2” (155 x 52 x 233 mm), the FT-857 is the world’s smallest full-power HF/VHF/UHF multimode transceiver! Its rugged case design is a masterpiece of ergonomic design, with often-used switches and knobs conveniently positioned for easy access.

 High-Performance Receiver Design

Building on the acclaimed performance of the FT-1000D, Mark-V FT-1000MP, and FT-897, Yaesu’s engineers have crafted the FT-857’s front end for a very low noise floor, along with wide dynamic range. Utilizing an up-conversion architecture for HF with a first IF of 68.33 MHz, the FT-857 features a double-conversion superheterodyne system (triple conversion on FM), with the 2nd IF at 10.7 MHz. Extensive bandpass filtering in the front end, along with careful device selection and gain distribution, yield a receiver system ready for the strong-signal challenges of today’s crowded bands!

 Wide Frequency Coverage

Providing transmitter coverage of the HF, 50 MHz, 144 MHz, and 430 MHz Amateur bands, the FT-857 also includes receive coverage on 100 kHz to 56 MHz, 76 to 108 MHz, 118-164 MHz, and 420-470 MHz. Enjoy the excitement of public safety monitoring, along with weather broadcasts, AM and FM broadcasts, aviation communications, as well as the action on the Ham bands! FT-857D includes the 60 meter band. HERE ARE THE FREQUENCIES.

 Memory channels M-601 through M-605 are pre-programmed, at the factory, with the permitted frequencies in the 5 MHz band, and the USB mode is automatically selected on these channels. Versatile Memory System

 

The FT-857 provides up to 200 “Main” memory channels, each of which may be named with an Alpha-Numeric label of up to eight characters. These 200 Memories may be separated into as many as 10 Memory Groups of 20 Memories each. For added convenience, you also get a “Quick Memory” and a “Home Channel” on each band, plus ten pairs of band-limit memories, to let you restrict operation to a sub-band, if you like.

 Digital Signal Processing STANDARD ON THE D MODELS

For superior interference rejection and transmitter “talk power,” the FT-857’s optional DSP circuitry enhances both sides of the communications circuit. The FT-857’s DSP Unit features a 24-bit high-tech D/A chip for signal processing. Included are Bandpass Filter, Auto-Notch, and Noise Reduction filters, along with a Microphone Equalizer. THIS FEATURE WAS TESTED BY JIM, KG0RD AT THE LEWIS AND CLARK SPECIAL EVENT STATION AND HE REPORTED THAT  HE FOUND THIS FEATURE TO BE HIS FAVORITE AND HE WAS ABLE TO TUNE OUT ADJACENT STATIONS AND ZERO IN ON THE DESIRED STATION HE WANTED TO WORK. TIME AFTER TIME HE FOUND THAT THE DIGITAL SIGNAL PROCESSING WAS A VALUABLE TOOL IN TALKING TO DISTANT STATIONS.

 Big Radio Tuning Dial and Outstanding Ergonomics

Ease of operation of the FT-857 is enhanced by the large-diameter (1.7”) Main Tuning Dial, similar in size to the tuning knob of many base station rigs. Selectable tuning steps of 2 kHz/4 kHz per revolution allow easy navigation around your favorite bands, while important keys and switches are strategically placed around the front panel for quick access.

OPTIONS AND ACCESSORIES MY COMMENTS ARE IN RED
Antenna Tuners
FC-40	The FC-40 is a new, wide-range Antenna Coupler for the FT-857 and FT-897 Series of Transceivers. The FC-40 is a microprocessor-controlled antenna impedance matching network designed for use with all versions (original and “D”) of the FT-857 and FT-897 HF/VHF/UHF Transceivers. The FC-40 makes use of control circuitry inside the transceiver, allowing the operator to monitor and control operation of the FC-40, which mounts near the antenna feedpoint. Fully waterproof, the FC-40 may be mounted outdoors in exposed locations, and will handle a 100 Watts of transmitter power. The FC-40 is designed for operation on 7 ~ 54 MHz, when using an 8’ whip like the YAESU YA-007, or on 1.8 ~ 54 MHz when used with a random-length wire longer than 66’. Matching time is typically five seconds or less, and the required drive power is 4 ~ 60 Watts. The FC-40 sports a whopping 200 match-setting-point memories, for instant recall of the tuning settings.
