AM Mode 

Pressing the [NAR] button selects a bandwidth of 6 kHz. 

FM Mode (28/50 MHz Bands) 

Pressing the [NAR] button selects a bandwidth of 9 kHz. 

 
Advice: 

 

When the narrow bandwidth is selected, “NAR” icon will appear in the display and 

reduce the bandwidth on the WIDTH indicator in the display. 

 

The bandwidth applied when the [NAR] button is pressed may be adjusted using 

the Menu item. This allows you to customize a quick-switch “Narrow” bandwidth 
matching your operating needs ( __: Default). 

SSB mode: 

Menu item “103 rdsP SSB NAR” 

 200/400/600/850/1100/1350/1500/1650/1800/1950/2100/2250 Hz 
CW mode: 

Menu item “094 rdsP CW NARR” 

 25/50/100/200/300/400 Hz 
PSK mode:  Menu item “097 rdsP PSK NAR” 
 25/50/100/200/300/400 Hz 
RTTY mode:  Menu item “100 rdsP RTY NAR” 
 25/50/100/200/300/400 Hz 

 

When the [NAR] button has been pushed so as to engage the narrow filter, the 

[WIDTH] knob will be disabled, but IF Shift still is operational. For many 
applications, you may find that simple adjustment of the [WIDTH] knob, instead of 
engaging the Narrow filter, may be satisfactory for interference reduction. 

 

When you press the [NAR] button in the FM mode, both the transmit and receive 

bandwidths are narrowed. 

Note: When the [NAR] button is pressed, the [WIDTH] knob no longer functions.
