No doubt super weird! All of these frequencies are occupied on the Novosibirsk, Russia KiwiSDR (and others) with a loop of Гимн России by Lube (the Russian anthem played by Putins favourite band). This includes the station on 8001 kHz, which has been at it for months. I was shocked to come across all the other frequencies. This receiver is way out in Asiatic Russia and each frequency has a different strength and transmitter signature (e.g. some have a bit of LSB, some have a weak carrier, some have wider audio, etc). I am not sure how this could be one person. They are not all synchronized with the music, but at 0449 UTC they all went silent or had only a buzz then all went back to music at the same time (still at different parts in the song). At 0500 UTC they all started buzzing again.
Really weird!
