This is a peculiar CW, and if you look on Youtube you'll find another dozen recordings of the same broadcast, all of varying fidelity.

That is the sound of a maritime coastal station SVO in Pirgos, Greece. They broadcast on 8424 KHz providing VHF and high frequency radio telephone and high frequency simplex teletype over radio (SITOR) services to seagoing vessels. I'll post about SITOR some other time. More here.That message is "DE SVO" then a long beep.  DE is a shortwave abbreviation for "this is" making the message: "This is SVO."
