I'm listening on the Twente WebSDR to a CW transmission on 6780kHz that consists of a number of 1 second dits followed by a longer dah, then approx 3 seconds of silence before the sequence repeats. The number of dits in each cycle is generally 19 but occasionally it is much less. Also the long dahs can vary in length.
I'm assuming its some pirate beacon??
