[Elecraft] S-meter / NB

[Ken Lotts]

Only a comment on the NB

I can only get my NB to make a difference when certain kinds of noise are
exposed to it.  The click igniter on my gas stove makes a noise that the
blanker can noticeably reduce.  However a stick blender and a sewing machine
do not.  I am convinced that the blanker works but I have only found one
noise source that it really does anything with so far.  I have read in the
archives about some hams that have increased the blank period (by adding
more capacitance in the NB2 setting) and have conquered certain noise
problems such as an electric fence.  I am likely going try the same just to
see what the difference is.

Hello guys,

When I connect my K2 to a dummy load, the S-meter will lit up with one
LED but *only* on USB mode when in receive.
The SSBA is set to 2
I  did go through the S-meter alignment procedure but it didn't help.
Any suggestions what this could be?



Second
How good is the Elecraft Noise-Blanker unit?
I'm living in an area with quite a lot of motor QRN (Ventilation boxes).
The NB isn't doing anything with that.
I also have a Drake TR7 (great radio) and the NB is reducing the rattle
with more then 30 dB!
How they did it, I dont know but my Ten-Tec Paragon can't beat the TR7
NB as well.

Is there a good way to check if the NB is working properly or as intended?

Thanks for answer(s)


Evert, PA2KW
