It looks like someone is using my call sign. I got eQSL’s from amateurs I did not work. Last week 3 times (see photo) so I think there is a pirate active with my call sign. A few weeks ago I rejected an eQSL from an UA station and he send me an email that he was really working me. Most of the time SSB QSO’s, which I rarely do. Last week I wasn’t active at all. I don’t know what I can do about it. Should I inform Agentschap Telecom?
