Narrow (Nar) One-Touch If Filter Selection - Yaesu FT-950 Operating Manual

NTERFERENCE
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 [ SELECT ( 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
( 1.8 kHz )
CW 100 ~ 500 Hz
( 500 Hz )
RTTY/PKT-L/PKT-U 100 ~ 300 Hz
( 300 Hz )
PKT-FM

FM ( 28/50 MHz Bands )

DVICE
When the narrow bandwidth is selected, the "
icon will appear in the display.
Even if the [ NAR ] button has been pressed to engage
the narrow filter, you may adjust the narrow IF band-
width by rotating the [ SELECT ( WIDTH )] knob (re-
quires pressing the [ WIDTH ] button). The IF SHIFT
still is operational (requires pressing the [ SHIFT ] but-
ton). For many applications, you may find that simply
pressing the [ NAR ] button instead of adjustment of
the [ SELECT ( 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.
