[Elecraft] K4HD question

[K9MA]

I've never found the K3 noise blanker to be very effective on power line 
noise, and I've tried all possible combinations of settings. If the K4 
noise blanker were really effective on line noise, I might buy one.

The blanking used in direct-sampling should have an advantage on complex, high-duty-cycle noise sources, while the hardware blanking modules used in the superhet may have an advantage with extremely short pulse sources. We'll be extensively testing and comparing them.
