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:
MODE
2nd IF
( 8.2MHz )
SSB
2.4 kHz/ATT
CW
2.0/2.4 kHz
AM
RTTY/PKT/USER
2.4 kHz
ø 1: You can select the bandwidth via menu selection 5-0 . The first value (bandwidth) is factory default.
ø 2: You can select the bandwidth via menu selection 5-2 . The first value (bandwidth) is factory default.
ø 3: You can select the bandwidth via menu selection 5-4 . The first value (bandwidth) is factory default.
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
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.
Note 2 - The 2nd IF (8.2 MHz) 2.0-kHz BW filter (Yaesu P/N YF-114SN) and 250 Hz BW filter (Yaesu P/N YF-114CN)
and 3rd IF (455 kHz) 2.0-kHz BW filter (Yaesu P/N YF-110SN), 500 Hz BW filter (Yaesu P/N YF-115C) and 250 Hz BW
filter (Yaesu P/N YF-110CN) are option.
Note 3 - The Sub Receiver use a double-conversion circuit with 47.21 MHz and 455 kHz intermediate frequencies. Both
the 6.0 kHz and 2.4 kHz filters are selected automatically according to mode, and with the optional 500 Hz Collins me-
chanical filter (Yaesu P/N YF-115C) installed and enabled via menu programming, it can be selected for CW operation.

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 long-duration pulses) and its
blanking level via menu selection 2-8 .
