Yaesu FT-857D 100W All-Band Multi-Mode Mobile Transceivers provide base station-type performance from an ultra-compact package that's ideal for mobile or external battery portable work. Wide frequency coverage, outstanding receiver performance and the convenience of optional remote-head operation make the FT-857D the expert's choice for high-performance mobile operation!

The new FT-857D version includes coverage of the U.S. 60-meter (5 MHz) band, plus the previously-optional DSP circuitry, at no additional cost!

Yaesu's FT-857D is the world's smallest HF/VHF/UHF 100W multimode transceiver! Its rugged case design is a masterpiece of ergonomic design, with often-used switches and knobs conveniently positioned for easy access.

Building on the acclaimed performance of the FT-1000D, Mark-V FT-1000MP, and FT-897, Yaesu's engineers have crafted the FT-857D transceiver's front end for a very-low noise floor, along with a wide dynamic range. Utilizing an up-conversion architecture for HF with a first IF of 68.33 MHz, the FT-857D 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!

Providing transmitter coverage of the HF, 50 MHz, 144 MHz, and 430 MHz Amateur bands, FT-857D transceivers also include 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 transceivers provide 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.

For superior interference rejection and transmitter "talk power," the FT-857D transceiver's DSP circuitry enhances both sides of the communications circuit. The 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.

Ease of operation of FT-857D transceivers is enhanced by the large-diameter (1.7 in.) 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.
