“Listen before you choke.” might be an appropriate subtitle for these two most helpful and informative YouTube videos produced by Dave Casler KE0OG one of the best sources I know of for reliable information regarding all things amateur radio.
Below is part 1 of 2 of a presentation Dave Casler KE0OG made to the Rochester Amateur Radio Association (RaRa) on 3 June 2020 on the subject of noise (QRN) and what can be done about it. It's a nice survey of noise sources. Part 2 will cover the second half of the presentation.
Below is the second part of the Noise presentation, as given to the Rochester Amateur Radio Association by Dave KE0OG. Thanks to Dave for all he contributes to this great hobby.
