4-2-16. Noise Blanker
@NB 1 switch
When pulsating
noise, such as that caused
by
automobile ignitions is encountered, place the NB
1 switch ON.
This switch will not help to eliminate atmospheric
or line noises, but pulse type noise.
@NB 2 switch
Noise
blanker 2 is used for long duration
pulse
noise,
like the
"woodpecker".
To reduce
"woodpecker" radar noise interference, set switch
NB
2 to the ON position
(NB 2's effectiveness
depends on the specific type of interference).
If
you use NB 2 for short duration pulse noise, the
receive
tone may
become distorted,
making
it
difficult to hear.
Unfortunately
no
noise blanker
can remove
all
different types of interference, but the two noise
blankers that
have been
provided
in the TS-
950SDX are effective in most cases.
If there is no "woodpecker"
present, the switch
should be in the OFF position.
@MAIN NB LEVEL control
Controls the noise blanker operating level.
Use only the minimum level necessary.
@SUB NB LEVEL control
