Howdy Rolf!
It is great to hear from you! I look forward to completing a contact with you on 6m
EME as soon as your line noise problem is cured ;-)

Dear Lance
You mentioned the other day on the VKlogger that I should get a K3.
Several other people have come out with the same suggestion. I just
wonder wether your comment was based on my mention of incurable
line-noise or not.
Yes, that was why I mentioned it. The K3 has a reputation for very effective noise
blanking. I have one here but don't have bad line noise.
I have heard about a new “intelligent� noise blanker that fills the
holes left by blanking the noise spike, with intelligent information,
sort of a continuation of the data received just prior to the start of
the noise pulse. I cannot, however, find any mention of this on the web.
As a matter of fact I don’t even know what rig this relates to. My
impression is it might be the Flexradio SDR, but I find no mention of it
on their site either…..
I was just wondering if you by chance know what I am talking about and
could point me in the right direction? I actually had this idea myself
several years ago, but did lack the technical knowhow to persue this any
further at the time, hi.
Yes, I have heard about that, but I can't recall if it is in the K3 or not. The K3
Noise Blanker has some different components and each are variable. Of course, the
firmware is being constantly updated, but I don't think there have been many changes
to the NB...I don't remember seeing anybody complain that it needs enhancing!
A quick Google search resulted in some additional information for you:

There also is an audio file I found of the NB performance:

It surely would seem this could be a “kill all� solution for people
in a situation like mine! Even EME could have another chance of life if
this really works!
Well, one solution would be to mount two yagis side by side and elevate them...I am
sure your noise would go down quickly as you begin to elevate.
But maybe there are some K3's down in PY1 region that are not too far away from
you...and you could go actually try one in person. GL Rolf, and best Holiday Wishes
to you too! VY 73, Lance
Any info appreciated!
Merry Xmas and a Very Happy New Year with lots of NEW ONES!
