I stumbled over an interesting documentary on radio jamming. You have probably seen it, but just in case you haven’t, here is a link.
I had not seen this before, Gary. Thank you!

A little dated, but still a very informative piece. Pretty much filled in any unknowns that I had about jamming, especially from the USSR. An interesting side note. Being of Ukrainian origin, I always enjoyed following both the VOA and Radio Svoboda services in that language. Of course Svoboda was always very heavily jammed, although I’d have no issues receiving VOA. I still remember hearing them via Greenville signing on with Yankee Doodle. I used to hear them clear as day using a crystal radio from my childhood home in Toronto, ON. As for the jamming, I was amazed how well RFE/RL was heard when I spent 6 weeks in New Zealand, back in 1983 or so. Crystal clear, and very strong, without a hint of jamming. All this on a little Sony analogue radio, using only the whip. It finally donned on me, that New Zealand was the antipode to Spain/Portugal, where RFE/RL once had a lot of transmitters. No wonder reception was so amazing!
Bob Marley did a very sarcastic song about this same phenomenon too.
