  1. looking for any information about 3W5JA operation. I’m getting ready to publish extensive article regarding amateur radio expeditions, in the region. Any information you can provide will be greatly appreciated.

    1. Dear Oleg,

      If this is about a past operation you may perhaps ask Bac Ai XV2A about it. His e-mail address is (xv2a null@null radioclub .

  2. 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).
    Please attention.

  3. About this issue. last time also see some pirate callsign and can’t check it in I will help monitor in PSK31 RTTY and JT65.
