Welcome friends,

I am a member of the German Radio Amateur Club DARC, Stuttgart section, DOK P11


                   ATNO 315 Juan de Nova in RTTY                        

                             Heard Island & Juan de Nova now in all three modes


This is my QSL card. smiley The picture is showing me and my family in original "Rottweiler Narrenkleidle" (Carnival costumes).


This is the shack. The TRX is now a Kenwood TS-590.


The antenna for 10/15/20m is a Fritzel FB-33 three element tribander beam. Below the beam you can see a Rotary Dipole, made of 2 fishing rods. The feed is a symmetrical line ending in a homebrew matchbox with high power coils and capacitors and a microcontroller and bistable relays. In the shack is the SWR- and frequency meter and the controller itself with 2 more µC's. The Software contains two optimization routines, a particle swarm algorithm and a gradient method. After automatically match everything is stored for each frequency. After that the outdoor unit (the matchbox itself) becomes powerless due to the bistable relays. So no noise during reception or failure during transmission can occur due to RF Power. With this I managed to reach VK barefoot on 40m :-)



For 40m and 80m I am using a short dipole with 2 traps on each side, hanging down from the ridge in an inverted V configuration. On this picture you can see a GPA30 which I used before the FB33 until October 2011.

The Vertical (GPA30) caused a lot of problems in my shack due to sheath currents and picked up a lot of noise. With the beam conditions are much better!



DXing I like the most, since march 2011 I worked 315 DX entities. Turkmenistan and Lybia not yet acknowledged. DXCC in three modes, WAE 1-3,WAS, WAC and DLD 100 are the most important diplomas I got up to now. Other ham-activities are contesting and ARDF.

I am member of the AKAFUNK, so I am often using the clubstation of the University of Stuttgart DK0SU

Hpe cuagn!
