Hello n2avh - you've probably heard Zeppelin Radio from Greece.
I was still receiving them after midnight around 0115 UTC at 6939.87 S9+15 but I didn't open the thread when I went to sleep.
This type of music is typical for this station, it also adds blocks of Greek songs.
The Opearor rarely gives the ID in English and Greek in a rather low, calm voice.
The ending FRQ xxxx,87 is always characteristic.
Via ocean pickup reports do happen, so congratulations on keeping an eye out!
