Hi Karsten,
My KNB2 worked w/o problems. Since the KNB2 blanks out continuous noise
within certain timing limits you need to test with another source.
To learn more about the KNB2, look here:

On 40m , with low threshold, I get "ghost"-signals. The manual
recommends to spend an additional capacitor. OK.
But what I expect - the blanking of noise - does not happen at all. As I
have no Noise-source, I tried to switch workspace-lamps on and off. That
gives me beautiful strong clicks in the receiver. Unfortunately I have
the same strong clicks when the KNB2 is activated. Nothing is blanked.
Is there a way to test the KNB2? Anything that can be measured? Do I
need a different noise-source?
