K3 NB & NR

I recently had an issue with electric fences (living in a rural environment), the AGC PLS did not seem to make a lot of a difference and the noise blanker was unable to mask the loud clicks.
Now with Beta 3.27, while everyone is talking about noise reduction, I notice that the noise blanker can suppress the strongest fence clicks and the AGC PLS does make a (big) difference! Quite a change...
I do not remember reading anything about this but it seems not only the NR was improved.
Thanks!

Re: K3 NB & NR

I have had some results like Richard, on 40 meters the Chinese dragon
has been active again and in the past the K3 is useless against this type
of radar. Much to my surprise it blanked the Dragon this time, I have
some distant power line noise that I was also never able to blank and
now the K3 blanks that decently as well.
I do not think there was any mention of changes in the NB and perhaps
there ware none directly, but there sure have been some side effects in
any case, works much better than before at least on this K3.

Re: K3 NB & NR

Which noise blanker are you and Richard talking about - the hardware
blanker or the DSP blanker?

Re: K3 NB & NR

Bob, for me its both, on the Dragon it takes both to do the job,
DSP T2-5 and IF Nar 5 removed the Dragon quite well ..
On the distant line noise I can sometimes get by with just the
IF blanker, but usually takes both there also. But less aggressive
settings.
