[Elecraft] KNB2 - How can I tell if it is working?

[Mychael Morohovich / AA3WF]

Bill / AA4LR asked," Is there something I can measure with a meter or a scope to assume me the KNB2 is doing it's job?"

 
As you know, the noise blanker is designed to work against pulse type noises such as that caused by automobile ignitions, electrical appliances, motors, light dimmers, etc. 
 
I tested mine on the gas stove's automatic igniter and it worked like a charm. I also tried it successfully against a Kitchen Aid mixer and  some QRN on the lower bands. Not nearly as scientific as a meter or scope, but as they (who, exactly?) used to say, the proof is in the pudding.
