into consecutive QMB Memories.

Pressing this button recalls one of up to five Quick
Memory Bank memories for operation.
NAR
(

Switch
In the SSB/CW modes on the Main band (VFO-A), this
button is used to set the bandwidth of the DSP (digital)
IF filters to a user-programmed bandwidth (default
values are SSB: 1.8 kHz and CW/RTTY/PSK: 300 Hz).
ADVICE:
When
[
NAR
]
has been engaged, the
[
WIDTH
]
knob
will be disabled, although the
[
SHIFT
]
knob still works
normally.
In the SSB/CW modes on the Sub Band (VFO-B), this
button is used to toggle the receiver’s bandwidth be-
tween wide (2.4 kHz) and narrow (1.0 kHz).
ADVICE:
When the Sub Band’s (VFO-B) optional YF-122C (500
Hz) or YF-122CN (300 Hz) CW narrow filter is in-
stalled, the optional narrow filter will be activated when
the
[
NAR
]
switch has been engaged on the CW/RTTY/
PSK modes.
In the AM mode, this button is used to toggle the
receiver’s bandwidth between wide (9 kHz) and nar-
row (6 kHz).
In the FM mode on the 28 MHz and 50 MHz bands,
this button is used to toggle the FM deviation/band-
width between wide (±5.0 kHz Dev./25.0 kHz BW)
and narrow (±2.5 kHz Dev./12.5 kHz BW).
Pressing the
[
A
]
or
[
B
]
button (located above the
[
MODE
]
selection buttons) will select either the Main
band (VFO-A) or Sub band (VFO-B) for individual
bandwidth setting.
