Just worked 4U1UN on 20m CW (1710 UTC). Fast and good operator. I read 4U1UN is preparing to be back on the bands, but I'm wondering if this was the real one or again one of these pirates who fooled me in the past? (JX7W comes to mind) Would be an ATNO for me. <EDIT> Now (1738 UTC) worked him on 20m FT8 (fox/hound mode). Running up to 5 slots.
