Features
The 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 6 m, the FT-450 includes operation on SSB, CW, AM, FM, and digital modes — a comprehensive performance package for field operation.
Designed for use from an external DC power source, the FT-450 provides 100 watts of output from a 13.8 V external 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.
Advanced features often found only in large base-station transceivers include dual VFOs; split-frequency operation; DSP (bandpass filtering, noise reduction, notch, and microphone equalizer); IF shift; clarifier (R.I.T.); IF noise blanker; AGC fast/slow/auto/off; RF gain and squelch; IPO and receiver front-end attenuator; VOX; built-in electronic keyer; adjustable CW pitch; built-in CTCSS encoder/decoder; time-out timer (TOT); computer interface; and cloning capability.
