The Yaesu FT-450 is a rugged, innovative multi-band, multimode portable transceiver for the amateur radio HF/VHF bands. Providing coverage of the 160-10 meter bands plus the 6m, the Yaesu FT-450 includes operation on the SSB, CW, AM, FM, and Digital modes, yielding the most comprehensive performance package available for field operation.

Designed for use from an external DC power source, the Yaesu FT-450 provides 100 watts of power output from a 13.8-Volt external power supply.

The multi-function Liquid-Crystal Display includes various backlighting, which may be disabled for battery conservation. The display includes bar-graph indication of power output, ALC voltage, SWR, and modulation level.

Among the advanced features of the Yaesu FT-450 are many incorporated only in large base-station transceivers. These include Dual VFOs; Split-Frequency operation; Digital Signal Processing (Bandpass Filtering, Noise Reduction, Notch, and Microphone Equalizer); IF Shift; Clarifier ("R.I.T."); IF Noise Blanker; AGC Fast/Slow/Auto/Off selection; RF Gain and Squelch control; IPO (Intercept Point Optimization) and a receiver front-end Attenuator; VOX; Built-in Electronic Keyer; Adjustable CW Pitch; Built-in CTCSS Encoder/Decoders; and Time-Out Timer (TOT) functions; Computer Interface capability; and Cloning capability.
