[UPDATE] Audio recording credit FY5KE of ZD9BV CQing with no takers:

[APRIL 25] – Andy ZD9BV has again been active. This time working southern European stations on 15CW; he seems to prefer 21042 for future reference. Recording by IZ0OZD.

[APRIL 24] Initially reported as a pirate station, we now have confirmation that the real ZD9BV (Andy) is again QRV as of the last few days after being off air for some years. On April 4th, his callsign was being pirated, however at that time local friends on the island mentioned he was beginning to set up some antennas.
