Hi, I'm Arthur from Berlin. I was born in Moers - a small city in Germany near Duesseldorf. I'm in Berlin since 1971 . I have studied electronics and economics and finished with dipl. engineer. I made my hamradio license 1982. My hobbies are hamradio, music - production also, watersport, fishing and computering, mathematics/physics and much more...... I worked at the IBM company and finished my work end of year 2000.

A small film in the near of Berlin from antenna day 2011 : https://www.youtube.com/watch?v=nhds54td95c
Now a small film from DO1HBF about the small antennas: https://www.youtube.com/watch?v=XmBaLyaCio0
On my homepages you can read many things about me, my interesting hobbies, my small antennas for shortwaves (they are only 5 - 20 cm long, builded from hairspraycans and with a very good efficiency) also the antenna building description.
73 de DL7AHW
The begin - my first 80 m (long) antenna 2001/2002, 45cm long. Peter,dl2fi and I talked about my antennas 2002....
