Many thanks to SWLing Post contributor, Gary (W4EEY), who writes:
I want to recommend an excellent presentation on RF Interference from
the Radio Society of Great Britain (RSGB) Convention in 2015. The
presenter is Ian White, GM3SEK, who has a Blog website here:
You can find the presentation video on YouTube here:
The presentation runs for about one hour and contains some valuable
information to help you fight noise and interference in your shack.
Thanks for the tip, Gary!
