On HF I go by Tom.

QSL Policy:

QSL OK via bureau, LoTW, eQSL or direct. Paper QSLs are preferred (I love and collect Paper QSLs).

Stations outside Europe sending QSL direct, please include a self-addressed envelope, 2 Green Stamps are nice to have, but not needed.

Europe stations sending QSL direct, no SASE or IRC needed, just send your card, I'll do the same.

SWL Reports are also welcome. Today's SWLs are tomorrow's Hams.

Every received QSL will be answered 100% sure. If you don't QSL, what is the sense of haming??

I became interested in SWL and Ham Radio in 1987 as a doctoral student of chemistry at the University of Kaiserslautern, when I bought a Yaesu FRG 8800 shortwave receiver and spent many hours listening to sw broadcast stations and the ham bands. After graduating from University, there had been first my profession as a chemist and hobbies as amateur astonomy and programming web applications in PERL. Then in 2013 I rediscover my interest in ham radio and in October 2013 I have passed the amateur radio examinaton and got the ticket for class E and the callsign DO9ZY. In May 2017 i have upgraded to Class A and the new Call DF9TW.

I am a member of ARRL (American Radio Relay League) and DARC (Deutscher Amateur Radio Cub) with the local group DOK K09 and similarly a member of the European PSK Club, Belgium Digital Modes Club , Croatian Digital Group, Digital Modes Club and Natal Digital Group.

Mostly active in PSK, equipment: MacBook Air, microHAM USB III interface, Fldigi 3.22.02 running on Mac OS X 10.11.

Retired!! Now more time for my hobbies, especially Ham Radio!! Trying to learn CW. I'm almost there :-)
