Narrow (Nar) One-Touch If Filter Selection - Yaesu FT DX 3000 Operating Manual

NARRow ( NAR ) o
Pressing the [ NAR ] button provides one-touch, mode-specific, selection of a narrow IF DSP filter setting that does not
require resetting the [ WIDTH ] knob.
Pressing the [ NAR ] button once more returns the band-
width control to the WITDH/SHIFT system. The factory
default bandwidths are:
o M
peRAtiNg ode
SSB 200 Hz ~ 1.8 kHz
( 1.5 kHz )
CW 50 ~ 500 Hz
( 500 Hz )
RTTY/DATA 50 ~ 500 Hz
( 500 Hz )

FM ( 28/50 MHz Bands )

 When the narrow bandwidth is selected, the "NAR"
icon will appear in the display.
 If the [ NAR ] button has been pressed to engage
the narrow filter, you may still adjust the narrow IF
bandwidth by rotating the [ WIDTH ] knob. The IF
SHIFT is also operational. For many applications,
you may find that simply pressing the [ NAR ] button
instead of adjustment of the [ WIDTH ] knob, may be
satisfactory for interference reduction.
 When you press the [ NAR ] button in the FM mode,
both transmit and receive bandwidths are narrowed.
