Amen! The K2 NB is particularly poor when using low level rx only ants as noise pulses are heard in audio, but are not adequate strength to trigger the blanking mv.

These blankers seem completely ineffective on all of the various types of power line noise I've encountered, unlike the more sophisticated blankers in most other rigs produced in the past 25 years. The blankers in my ancient 22-year-old TS-430 and 11-year-old TS-50 work wonders in comparison. > > Maybe it's time for a re-design of the Elecraft blanker system. > > 73, > Mike / KK5F > > > ___ > Elecraft mailing list > Post to: Elecraft@mailman.qth.net > You must be a subscriber to post to the list. > Subscriber Info (Addr.

Re: [Elecraft] Question about KNB2 Noise Blanker (Gain reduction inNB2 posit...
I find the KNB2 in my K2 to be very effective on the usual type of powerline noise I encounter. However there is a variant, which sounds the same to the ear, that the blanker won't touch. I don't have a 'scope so can't look at what the difference in waveform might be, but in general I am quite pleased with the blanker. That, plus the NR mode of the KDSP2 provides really good noise reduction.

Are there different versions of the KNB2? I haven't been impressed with mine compared to my 950.

I've had the opposite luck. My K2 takes out local electrical noise and ignition noise where my TS-570S and IC-746 noise blankers didn't do a thing. I've been very happy with the noise blanker in my K2 and think that's been the best option for the buck! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
