These, and many more really cool tidbits are in the extensive documentation on Flex site. Enjoy!
It would have been possible I think to make the noise mitigation blanket the whole receiver so all and any noise would be effected, but doing that would effect the receiver performance.
It seems some people do not have wide band noise, electrical noise, power lines. For me 40 Meter band is un usable without the wide band filter.
I have asked at various times before concerning how the 6K series works on electric fence pulses (real noise). but am not getting much for definite answers. Have you had a chance to actually test your 6000 series NB on this type of noise?
In my environment NB works very well in greatly reducing (although not completely eliminating), noise from my neighbor’s electric fence, which is the primary noise source here. WNB has no apparent effect on this or most other seemingly “correlated” noise situations, but similar to others’ reports it has worked very well for me several times when wide swaths of the spectrum were temporarily obliterated by a very strong noise.
