[Elecraft] How to test noise blanker

[Ken Alexander]

Based on observations after driving many thousands of
kilometers with a transceiver parked on 50.125, a sure
fire test of a noise blanker would be to position your
receiving antenna near just about any Chrysler minivan
that's more than a few years old.  

I can't explain why just them, but the evidence was
too obvious to ignore; they seem to radiate a lot of
ignition noise.
