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, mathematic/physic and much more...... I worked at the IBM company and finished my work end of year 2000.

Please have a look on my homepages: Please try the first address,

1.http://www.mydarc.de/dl7ahw/ or 2. http://dl7ahw.bplaced.net/

Here you can find the calculation programs in German: http://www.mydarc.de/dl7ahw/berechnen00.htm

and here the programs in English: http://www.mydarc.de/dl7ahw/berechnen00e.htm

 

On my hompages you can read many things about me, my interested 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.
