As I was spinning the dial I heard these oscillating sounds that I've never heard before. This went on for many hours, possibly more than 24 hrs. I've googled this frequency and found some other examples:

Surfing the Radio Waves: UNID signal plus XM

Mysterious whale song station on shortwave - YouTube

In this YT vid, the freq is very close to the 5450 khz RAF Volmet.

I read about these whale sounds but this is a first catch for me. I frequently (actually, every evening/night) spin between 8000-9000 khz but never heard it before.

Considering how long this tx went on for, just wondering if anyone else caught it.

And Sunday morning whatever the RX frequency was set to was being hit by the PLUTO II / Akrotiri OTHR. On the 8707 kHz freq with the audio feedback the OTHR was being retransmitted.

T!
