Then think again!
Armin, DK9PY informs:
If you have arrived at this QRZ page thinking that you have worked a station in China, you have obviously mis-read my temporary call sign of 6Y6N, or you have not listened correctly, or your CW reader or the cluster entry is telling lies. Do not trust cluster entries. I am currently in Jamaica (until June 3rd, 2015) and if you require a QSL, then you should go to 6Y6N for details or if you are sure you worked BY6N then you should go to China for the QSL.
