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!

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!

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.

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.

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.
