About

About Me

Hello! My name is Aljaž Žugič Jehart, callsign S57AZJ.

I am a young amateur radio operator from Ljubljana, Slovenia. I received my amateur radio license in February 2024 and since then I have been exploring radio technology, antennas, RF engineering and contesting.

My interests include:

  • • Contest operating
  • • RF experimentation
  • • Antenna design
  • • Electronics projects
  • • Radio software

Current Focus

Building efficient HF contest workflows and software-defined tooling for station automation.

School

School

I am focused on technical studies with strong interests in engineering, electronics, embedded systems and telecommunications. School projects often feed directly into my amateur radio experiments, from signal processing prototypes to hardware test fixtures.
