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......

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.
