■ Noise Blanker (Mode: SSB/CW/RTTY/AM) The Noise Blanker eliminates pulse-type noise such as noise from car ignitions. ➥ Push [NB] to turn the Noise Blanker function ON or OFF. • "NB" is displayed when the Noise Blanker is ON. When using the Noise Blanker function, received signals may be distorted if they are excessively strong or when used for noise other than pulses. In this case, set the Noise Blanker threshold level to a shallow position, or turn OFF the function. (see below) D NB Set mode To deal with various types of noise, the attenuation level and noise blanking duration can be set in the NB set mode. q H old down [NB] for 1 second to display the "NB" screen (Noise blanker). w P ush [Y](F-1) or [Z](F-2) to select the desired item. e R otate [MAIN DIAL] to select the desired option. • Hold down [F-3] for 1 second to reset to the default setting, if desired. r P ush [NB] to save, and return to the previous screen. 1. NB Level (Default: 50%) Set the noise blanker threshold level to between 0% and 100%. 2. NB Depth (Default: 8) Set the noise attenuation level to between 1 and 10. 3. NB Width (Default: 50) Set the blanking duration to between 1 and 100. ■ Meter peak hold function When the "Meter Peak Hold" item is set to ON in the Set mode, the peak level of a received signal strength or the output power is displayed for approximately 0.5 seconds.

The Noise Blanker eliminates pulse-type noise such
as noise from car ignitions.
➥
Push [NB] to turn the Noise Blanker function ON or
OFF.
•
“NB” is displayed when the
Noise Blanker
is ON.
When using the Noise Blanker function, received
signals may be distorted if they are excessively
strong or when used for noise other than pulses. In
this case, set the Noise Blanker threshold level to a
shallow position, or turn OFF the function. (see
below)
■
Meter peak hold function
When the “Meter Peak Hold” item is set to ON in the
Set mode, the peak level of a received signal strength
or the output power is displayed for approximately 0.5
seconds. (p. 162)
D
NB Set mode
To deal with various types of noise, the attenuation
level and noise blanking duration can be set in the NB
set mode.
q
Hold down [NB] for 1 second to display the “NB”
