General
The Yaesu FT-450 HF/50 MHz Transceiver is designed for Amateur Radio use. It provides a
general-purpose receiver covering 30 KHz through 56 MHz. The Transceiver range is broken
into 10 Amateur Radio Bands and 1 general purpose band to cover the remaining high frequency
spectrum. The variable frequency oscillator (VFO) setup for each band is remembered
individually as you switch bands. The details of what makes up a VFO setup will be described
when we get into the section on memory. The transceiver allows communication in using side
band, continuous wave, amplitude modulation, frequency modulation, and (when computer
driven) a number of data modes.

Controls
The FT-450 front panel contains 24 push buttons, 3 analog rotary dials, 2 rotary digital dials, a lighted
display, and three jacks. The small rotary digital dial (“DSP/SEL”) has 24 steps per revolution and also
functions as a push button. The large rotary digital dial has 100 steps per revolution. A number of push
buttons behave differently if held down for one second (adaptable).
Since there are literally hundreds of settings possible on the FT-450, a button, knob, or dial may be used
to control more than one function. The less often changed values are set by a sequence of buttons and/or
dials. For example, if you press the “F
■
” button (2
nd
from right mid height button), the letter F will
illuminate on the display. The upper right six buttons have two names on each. If the F is illuminated, the
button performs the function of the upper name and the F is extinguished. Otherwise those buttons
perform the function of the lower name.
Definitions:
f-press = press a button preceded by the “F
■
” button
t-press = press a button and hold for 1 second (adaptable 0.5, 1.0, 1.5, or 2.0 seconds)
