Welcome!

My name ist Christopher and I am from Kiel (JO54bi), the capital of Schleswig-Holstein at the coast of the Baltic Sea. Since June 2023, I am a licensed ham radio operator.

  • Two Retevis RT3S as my portables for DMR operation
  • Komunika GP-Mini-Dual VHF/UHF-Antenne for up to 300 W
  • Moonraker Whizz Whip HF/HF/UHF-Antenne for up to 10 W with FM resp. 25 W with AM/SSB/CW
