Glad you have at lest identified the source of this problem . . .
Back in the 70s suddenly a spurious signal appeared on 1880kHz. You could clearly hear that it was two stations from a local BBC AM Transmitter mixing together. This was very annoying, as it was one of the main SSB frequencies. Fortunately, one of the locals was an Engineer with the GPO Radio Services dept (our Regulator back then), so he got the BBC to sort it out quite swiftly. As I recall, it turned out it was rusty metal guy wires that were causing the mixing and re-radiating.
