Hi - Thinking of building my 2nd K2. I wondered what the consensus is on HOW WELL DOES THE NB WORK? in a K2?
In my spring #5422 K2 - I never could see much improvement in "noise" elimination. I had experienced a situation where we had major trucks near our house (cement job) - and the ignition or engine electrical noise was major. The NB, in either setting - semmed to do nothing noticeable to remove this type of noise. The repetitive "popcorn" hissing noise - sort of regular brownian white noise one hears on 40 and 20 - wasn't improved on either. I even built a 2nd NB kit from Elecraft - that didn't improve the noise operation either. The K2 itself appeared 100% in spec, filters all aligned with Spectrogram, and the rig passed every construction test and specification with flying colors. And it had 100% toroid guy toroids throughout. Maybe these are 2 cases of the type of noise that the NB doesn't deal with - what noise does it eliminate? I know on previous Icom and Kenwood rigs - NB did remove or at least diminish noises of these types? Is DSP the better way to go?
