The results when using the Noise blanker has been mixed for me. I dont
have any luck with nearby electric fences. I always need to use the Low
Threshold since the pulse levels are low. Sometimes it works sometimes
it does not. I have the same mixed results on power line noise when the
noise is aggressive and strong it works well. However it requires a
specific level and type of noise to achieve the spectacular results
some have demonstrated and reported. I am also disappointed that
noise blanker does not work very well on rain static. Equally surprising
is that the noise blanker works on some types of ignition noise and wont
work on others. I would have thought that 2 stroke noise from motorbikes
and farm machinery would have been a easy task for this noise blanker,
not so. Again there is nothing wrong with my noise blanker. Every time i
think its broke and i turn it off i am shocked at what i am hearing! So
when it works it does work.
I have compared it to several other radios. One radio in particular the
TS830S has one of the most amazing all round noise blankers. All the
noise the Elecraft noise blanker struggles on the TS830S noise blanker
will handle on the low threshold setting. The same results can be had on
my FT1000D, my mobile TS480 also handles the noise in a more able
manner. The TS830S's noise blanker is a killer on rain static on a yagi,
the K2's struggles to cope in comparison.
My view is that the noise blanker needs a continuously variable
threshold control, likewise a variable pulse width. Changing component
values is just not a reality with noise appearing and disappearing. But
i think we will have to wait for the K3, for fixes!
