Term Explanation
: The Menu Mode permits you to make small changes
in the parameters of many of the functions of the
FT-450
. You can cus-
tomize the operations to your personal preferences.
MAIN DIAL Knob
This knob adjusts the operating frequency in the SSB/CW/DATA modes.
You may change the knobs function to also adjust frequency in AM/FM
mode via the Menu Mode.
When the Clarifier is activated, this knob adjusts the receiver offset
frequency.
AF GAIN
This knob sets the receiver’s audio
volume level. Typically, you will op-
erate with this control set between
the 9 o’clock and 10 o’clock posi-
tions.
SQL/RF GAIN Knob
In the factory default, this knob ad-
justs the gain of the receiver’s RF
and IF stages. Using Menu Item
“SQL/RFG”, this knob may be
changed to function as a squelch
control, which may be used to si-
lence background noise when no sig-
nal is present.
