Yaesu FT-450

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 DATA (6 pin) jack provides receiver audio and squelch signals and PTT control from an external packet TNC. The TUNER (8 pin) jack or DIN connector is used for the Yaesu FC-30 or FC-40 external automatic antenna tuner. The LINEAR (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.
