Hi, I am Kostas sv3ora and I have developed a revolutionary noise blanker that works directly onto the antenna signal and does not distort the cleaned signal.
You can find the project here http://qrp.gr/nr1/
The youtube playlist with videos from HAMs around the world that have it here https://www.youtube.com/playlist?list=PL0KwxiKZqJ1TzQpscf3voh5CR1c30WLD_
The manual here http://qrp.gr/nr1/sv3ora_NR-1_Antenna_Noise_Blanker_manual_EN.pdf
Also on the page http://qrp.gr/nr1/ there are reviews on eham publications on magazines and reviews by HAMs testers.
HAMs can purchase it from the company https://shop.elisys.gr/products/nr1/ that sells it. Their email is shop@elisys.gr
This will help A LOT HAMs that have severe power line noise, to get rid of it effectively, without too much effort (no separate noise sampling antenna is required!).
Thanks for the AD!
