What's the point of being ham nerds if no one cares what really happened here? 1.65m is FM (90 MHz) which as told is wrong. Can't pick up FM like this, it is NOT simple like all the AM stories. Chrome books don't have inbuilt radio as far as I can see (Why not is a good question for another time. After the phone cartels destroyed radio on phones why doesn't Google put it in Chromebooks? Would it create awkward questions for their phone cartel department.) They say coiling it doesn't change it - The geometry of the cable does change the sound a little. I can't remember much, but I got the impression it got a little louder when I stretched it, although I could also hear it fine when wrapping it around in circles. Changing the geometry of the wire definetly changes the audio, even if by little They are in Brazil... not sure if that matters. ( Definitely FM -https://www.wikiwand.com/en/FM_extended_band_in_Brazil https://www.wikiwand.com/en/FM_extended_band_in_Brazil) They didn't hear the FM radio logo, it's a friend who did, so that's not a trustworthy data point. OPs account seems legit, so you could probably trust their personal experiences. It's probably either a AM re-transmission of FM or an AM station. The cord is not acting as an exact antenna.
