Weird signal jamming AM broadcast at 3480 kHz

[@Cezzerz]

the language is korean, and the voice you recorded comes from "voice of the people" which broadcast at 3480Khz. The siren is probably north korean jammers blocking the radio from being listened to by north koreans.

I sincerely appreciate you weighing in here with that information, as I was having a discussion with another person about which language was being spoken (and I guessed Korean or Filipino). Interesting that this one channel was possibly being jammed, while all of the mirror/simultaneous broadcasts were not. Again, thank you.

Hmmm. Almost sounds like a far away jammer over a closer broadcast. How long was the broadcast? did the "jammer" persist the entirety of the broadcast? Point of origin for each signal? Sounded Korean. So many questions.

[@CurtRowlett]

All good questions, but I'm not sure I can answer them. But, this is what I do know: As I continued to scan above that frequency, I discovered that the same broadcast was being simultaneously transmitted on at least four other stations that I passed by, and that none of the others had anything like this strange signal on top of them. That leads me to think that this was likely some sort of local RFI, perhaps. And because of the language barrier (I only speak English and a smattering of Spanish and German), I have no idea what the broadcaster was saying, or even which language she was speaking, possibly Korean or Filipino? I only listened to about 15 minutes of the broadcast and the signal was interfering/present during that entire time.

@@CurtRowlett I was listening for some Spanish, most Filipino languages (they have several) borrow several Spanish words. The voice broadcast was not as inflectional as Chinese, and sounded halfway between Japanese and Chinese, so pretty much Korean. 4 simultaneous broadcasts. does make one wonder. Wish I was in a position to Dx this.
