I built the noise blanker kit for my K2 s/no. 4905 (I think) a few weeks back, and I am beginning to wonder if it is working. I can not tell any difference between NB1, NB2, whether hi or lo threshold.
It is said that it works against the sort of pulse noise I get here from power lines occasionally, yet it makes no difference. Since all the cars in the family are diesel powered and I am some distance from a quiet country road, I have not had the opportunity to see whether it works on petrol engined ignition noise. My experience with noise blankers in other radios is that you can usually hear some change when it is switched in, but I don't. Am I expecting too much? Or could there possibly be a fault which would still pass the rx signal through the noise blanker board and yet stop the noise blanker working? Had I not read how good it is supposed to be, and had I not made it myself, I probably would not be asking the question!
