It seems that some unidentified stations (pirates) are operating CW and digimodes (PSK31 and JT65) with unauthorized and illegal callsigns. Of course these will not be valid for any award or diploma.
In recent days, there are some CW-JT65-PSK31 activities on radio amateur band with unknown 3W callsign.
– The ship callsign: 3Wxx without the zone number.
– Illegal callsign: 3W0xxx, zone zero is not use.
– Fake callsign (?): received on zone 1-2 not 3.
– Fake callsign (!): not authorized from owner (XVxx).
