4462kHz pulse on Shortwave.


'4462kHz pulse on Shortwave'

4462kHz pulse on Shortwave.
I first heard about this odd signal here -

This is how it sounds in Finland.
It is very weak and it comes in for a few seconds and then disappears back into the background noise.
Based on the time that I could hear it , and propagation modelling I would say it originates from China or South East Asia.
