The Yaesu FT-450 is an entry level amateur radio transceiver made by Yaesu. It transmits on eleven amateur bands, from 160 meters through 6 meters. It also has a receive frequency coverage of 30 kHz to 56 MHz. The FT-450 features an IF-DSP (width, notch filter, contour and noise blanker functions), which is uncommon for its price range. In addition to the front-end features the Yaesu FT-450 provides complete computer and accessories interface connections on the back panel. The <u>DATA</u> (6 pin) jack provides receiver audio and squelch signals and PTT control from an external packet TNC. The <u>TUNER</u> (8 pin) jack or DIN connector is used for the Yaesu FC-30 or FC-40 external automatic antenna tuner. The <u>LINEAR</u> (10 pin) output jack provides band selection data, commonly used for the optional VL-1000 solid-state linear amplifier. The DB-9serial port allows it to be controlled externally from a computer. Yaesu FT-450 models provide digital voice announcement - "select frequency, mode, meter reading" for visual impaired amateur radio operators.
