So how are you measuring the effectiveness of the blanker? Unless you have a source of noise pulses that match the blanker in that radio, how can you tell?
I have found that the power-line noises we get here will get totally blanked out by some radios, and not so much by another model. Just flipping that switch with the antenna attached is not much of a test.

I used a hair drill close to the radio and turned the NB off then on and no change . I have a uniden 66 and I did the same thing and that radios cut almost all of the noise when it was on turned it.off and got very loud. Tried a galaxy radio it worked perfectly so I decided to use my friends cobra 25 and his cut the noise down as well the ones I have it doesn't change on or off
