DF5SI

Thanks for stopping by on my site. This site is dedicated to the callsign DF5SI and my ham radio-related activities.

It is not only about Contesting and DX’ing but about ham radio for more than 40 years!

I established this site in the year 2000. Since that time, the internet developed very fast. Radio and communication technology did not stop in development either. The traditionally analogue radio design transforms increasingly into an entirely digital concept. Even more, the software sets the standards, as well as the limits today. We are part of this new and exciting time.

Anyway, I invite you to share my passion for ham radio.
