[Elecraft] K3S Noise reduction Test

[tomb18]

Just a note. This is with a small amplified  vertical receive antenna, the ncc1 and all fed through the k3 Rx loop. It's wwv, and the whole thing is switched in at the end of the video. 25dBm reduction in the noise. It's also really useful for eliminating acting one signal on top of the other. For example Am broadcast dxing... I can get rid of a strong am broadcast on top of a weak one. Now if only this could be automated and built in to the radio...

I think the ncc1 is under rated. Here is an example  of what it can do. I was plagued by a neighbour with outdoor high intensity lights which he insisted on leaving on during the day.. It was either this or blasting his house with 2.4ghz noise whenever his lights were on during the day... It's not the best video but it shows what you can achieve... https://va2fsq.com/wp-content/uploads/2013-Jan-15-20-43-43.avi 73 Tom

Don,
Thanks for the info, but as John said, I was suggesting a noise 
canceling setup...  I was not clear enough, my error.

73s and thanks,
