Operating and special calls:

April 1979:
I started listening to shortwave using a Yaesu FRG-7000 and had a lot of fun with different services like international broadcasting and amateurradio.

April 1990:
I got my licence 'DL1AH' (and also my SWL-identification 'DE5JLN').

Holiday-operation as OE4/DL1AH/p  Burgenland south of Vienna/OE near the hungarian border.

Since 2001:

On the left the operator. A rare picture using a microphone...
(most times the morse-key is my friend).

On the right there are 2nd and 3rd OPs Iris and Jana
on the wide beach of Amrum Island in 2006. Jana passed
away in November 2010 at the age of 11,5 years by
severe illness. She had lots of fun on that beach!

A much better pic of the operator is this:

No talk, no touch, no eye-contact - when operating CW!
