YAESU - FT-857D
The FT-857D, the world's smallest HF/VHF/UHF mobile transceiver, provides base station-type performance from an ultra-compact package that's ideal for mobile or external battery portable work. Wide frequency coverage, outstandig 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!
Ultra Compact DesignMeasuring 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 DesignBuilding 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 CoverageProviding 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!Versatile Memory SystemThe 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 (option)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.Big Radio Tuning Dial and Outstanding ErgonomicsEase 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.
Model Antenna Tuners FC-40
The FC-40 is a new, wide-range Antenna Coupler for the FT-450, 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-450, 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.
Antennas ATAS-120 Active-Tuning Antenna System ATAS-25 The ATAS-25 is a manually-tuned portable antenna system ideal for the FT-817, FT-897, and FT-857 transceivers. Capable of operating on the Amateur bands between 7 MHz and 450 MHz, the ATAS-25 is designed for mounting on a standard 1/4" camera tripod stud (tripod not supplied), and includes an innovative fine-tuning system allowing precise SWR adjustment in the field.

Are the 60-meter channels in my FT-857D off frequency?
Your attention is directed to ARRL's FAQ regarding 60-meter operation:http://www.arrl.org/FandES/field/regulations/faq-60.html
NTIA specifies channels in terms of "channel center" frequencies, where as amateur transceivers, in tuning a commercial channel, typically must be tuned 1.5 kHz lower than the specified "channel center" frequency. For example, for a "channel center" frequency of 5332 kHz, you tune a "traditional" transceiver to 5330.5 kHz.
So go ahead and try it. Set up an FT-817ND/857D/897D to the "5332" channel, and tune your FT-1000MP to 5330.5 kHz. Now transmit from the 817ND/857D/897D; you will find that you are precisely on frequency as you monitor on the other transceiver.
Note: If you program 5330.5 kHz into a "regular" memory from the VFO, it will be on the same frequency as the "5332 kHz" channel in the special 5 MHz memory bank, as the 60-meter bank (only) displays according to the "channel center" format.
