[Elecraft] Noise Blanker

[Ron D'Eau Claire]

Ignition noise from large trucks??? All of the ones I've seen are diesel -
no spark ignition at all! 

Such trucks often make a lot of hash from various electric motors, etc. -
just the sort of thing the NB can't touch. 

Did you remove jumper W5 from the K2's RF board when you installed the NB?

In my K2 # 5422 - I built two (2) NB kits, with no
luck in either doing much with "noise".  For sure
it did nothing on ignition/truck noise (3 cement
trucks outside our doors).  And it did nothing
to reduce or change what I call repetitive
popcorn white noise signals on bands.

Hooked up to a wet noodle wire antenna - I could
never verify any operation of NB at all.  Someone
suggested it only works in high signal level
noise situations.  Perhaps ....... K3NB?
