Biography

I got my novice amateur radio licence in 1979 and the callsign DG5DT was assign to me. In 1880 I pass the morse examination and I got the call DH4DAB. A year later I pass the advanced licence examination including 12 wpm morse exam and again the callsign was changed to DL9DAK. In spring 2015 I pass the US extra class license exam and the vanity callsign N9DAK was assigned to me.

I am a telecommunication engineer. My special interests in amateur radio are digimodes and higher frequencies as well as satellite communications.
