I ordered the noise blanker to see it if would take care of some noise I get from time to time in the RV park where I live when I'm working. It put it in the radio. (easy installation) turned it on in the configuration menu and when I activated it when the noise started it worked and had not trace of the noise I was hearing.

I was operating from J6 and experiencing frequent loud pulsing noises that made Qs alost impossible at times. On the off chance that the NB actually would help, I gave it a try and was amazed. The results show in my log! Without serious loss of signal strength, my receiver was able to continue unimpaired.No scientific data, no graphs , no numbers, ONLY results.. From home, my very high end rigs all have had NBs that were less than effective or impressive.
