48. BANDWIDTH Buttons (NOR/NAR1/NAR2) Buttons
These three buttons select the 2nd and 3rd IF fil- ters for the receiver (except in the FM mode). The LED inside each button glows red when the corresponding bandwidth is selected.
The available 2nd and 3rd IF filters are as follows:
49.NB Button
Pressing this button activates the IF Noise Blanker, which may help reduce many different types of man- made impulse noise (but not atmospherics). When the Noise Blanker is activated, the LED inside button will glow red.
You can select the Noise Blanker Type (for short- duration pulses or for

Note 1 - In the factory default condition, the SSB NAR 1 bandwidth is “2.0 kHz/2.0 kHz (2nd IF/3rd IF)” and the SSB NAR 2 bandwidth is disabled. If you set the SSB NOR bandwidth to “ATT/6.0 kHz (2nd IF/3rd IF)” via menu selection 5- 0, the NAR 1 bandwidth will be set to “2.4 kHz/2.4 kHz (2nd IF/3rd IF)” and the NAR 2 bandwidth will be set to “2.0 kHz/ 2.0 kHz (2nd IF/3rd IF)” automatically.
