Just received news from "DX_World" by Twitter that K6HFA plans to work from Tuvalu with callsign T2X.
I was really surprised (!)
For further operation, if he will use my call sign, PLEASE DO NOT SEND ME your QSL cards to avoid the maze and confusion.
For these operators (i.e. K6HFA ('new T2X'), WA3FPK ('new 9X0A') and others...) I strongly recommend a visit at QRZ.COM from time to time
