Branko, T6BP operates in difficult conditions, with a very high local noise level (QRN). Please keep in mind, very often he is not able to hear something that you can. So, please be patient and don’t call him if you can’t hear him.
If you made a QSO with T6BP on 10MHz (30m), try again on another band. 10MHz is not released to amateur radio in Afghanistan.
QSL via 9A6AA.
