Borrowing extensively from the FT-897 transmitter design, the FT-857D1s rugged power amplifier section utilizes Bipolar Transistor devices, providing low noise, low distortion, and high reliability. On HF and 6 meters, you get 100 Watts of clean power output , while on 2 meters you get 50 Watts out, and 20 Watts on 70 cm. Reliability is assured thanks to the extensive cooling system, featuring a thermostatically-controlled fan and aluminium diecast chassis.

Despite its compact size, the FT-857 is without peer in ease of access to the features and functions you need the most!

•BIG-RADIO TUNING DIAL AND OUTSTANDING ERGONOMICS:

Ease of operation of the FT-857D is enhanced by the large diameter 1.7" Main Tuning Dial
(10 Hz steps minimum), similar in size to the tuning knob of many base station rigs.
What's more, the SELECT knob allows "channelized" tuning in minimum steps of 1 kHz on SSB/CW, or 5 kHz on FM, for quick and easy tuning around the band. All important keys are strategically placed around the front panel, for quick access.

•EASY-TO-USE "SCROLLING FRONT PANEL" KEYS:
The compactness of the FT-857D is made possible by the easy-to-use "multi-function" keys, which allow adjustment of a number of transceiver operating functions during operation. Pressing the (FUNC) key allows selection of the operating function row, using the Selector knob, and you may then press the (A), (B), or (C) key, as needed, to change the setting. One row of keys may also be custom-programmed by the operator, allowing you quick access to a particularly important set of functions or Menu items.

• IF Shift:
Use the IF SHIFT feature to vary the center frequency of the IF passband, so as to eliminate interference above or below the current operating frequency.
•IF Noise Blanker:
Optimized for use in the mobileenvironment, the FT-857D includes a highly-effective IF Noise Blanker specifically designed for suppression of ignition and other pulse-type noises. The Noise Blanker's threshold is adjustable via the Menu.
•Intercept Point Optimization (IPO):
For reception on the lower HF bands, where low Noise Figure is not required, the IPO feature causes the RF preamplifier to be bypassed, allowing direct signal input to the first mixer. An input attenuator is also provided for very noisy conditions.
•Adjustable AGC:
The Automatic Gain Control (AGC) circuitry of the FT-857D's receiver may be adjusted, by the operator, for Slow or Fast recovery times. A convenient "Auto" feature programs "Fast" AGC for CW, and "Slow" for voice modes. And the AGC may also be turned off, if desired, allowing manual gain control from the front panel.
•Clarifier (R.I.T.):
For split-frequency pile-ups or to follow drifting signals, the Clarifier control provides up to +-9.99 kHz of adjustment of the receiver's frequency, without changing the transmit frequency. For wider-split pileups, the "Split" mode allows you to use VFO-A and VFO-B separately, too.
•RF Gain Control :
For noise reduction and/or variation of the AGC system threshold, the Menu allows the front panel's "Squelch" control to operate as an "RF Gain" control.
•VOX:
For hands-free Voice operation, the VOX system includes easy adjustments for both VOX Gain and Delay. A separate setting is also provided for receiver recovery time in the CW mode, as well.

For superior interference rejection and transmitter "talk power", the FT-857D's DSP circuitry enhances both sides of the communications circuit.
The Ft-857D's DSP Unit features a 24-bit high-tech D/A chip for signal processing.

•DSP BANDPASS FILTER:
Separate DSP Bandpass Filters for Voice and CW augment the analog filters for enhanced interference rejection. For Voice modes, you get 16 High-Pass Filter cutoff frequency selections, and 32 Low-Pass Filter selections, for a total of 512 combinations. And for CW, you may choose bandwidths of 240 Hz, 120 Hz, or a razor-sharp 60 Hz.
•DSP AUTO-NOTCH FILTER:
To reduce interference caused by annoying carriers within the audio passband, the DSP Auto-Notch provides a significant reduction in the interference level. If multiple carriers are present, the DSP will detect and notch all the carriers present.
•DSP NOISE REDUCTION:
The very effective Noise Reduction filter of the FT-857D utilizes as many as 16 noise-reduction algorithmn, for use in a wide variety of noise envitonments, without introducing appreciable distortion on the desired signal. Operator fatigue is reduced, and signal-to-noise ratio is significantly enhanced.
•DSP MICROPHONE EQUALIZER:
To match the Ft-857D's TX audio response to the waveform produced by your voice and the microphone in use, the DSP system includes a four-position Mic Equalizer circuit. The result is increased "talk power" as extraneous frequencies are suppressed allowing all available power to be concentrated into your voice's pattern.
