Welcome to the DCO Radio Site

The source for comprehensive information and resources in the field of unlicensed radio and SWL (Shortwave Listening).

And we are still in the process of building our Internet presentation

It was a "CQ DX" that led us to get together

Disrespect from AFU or HAM, i.e. amateur radio operators who “still” believe that they are something better

and think they have to be better than radio operators who do not have a license will NOT BE TOLERATED!

Amateur radio operators may think they have more knowledge or tradition, but that is a misconception because times have changed.

We want to promote radio in general, especially by holding radio contests, field days, and mountain and marine radio activities as well as supporting citizens and authorities in establishing communication connections in disaster cases, both personally and through licensing is possible.

Amateur radio operators and DCOs who are not licensed should cooperate with each other and not against each other.

We do not disturb Radio Amateur´s and they should not disturb us. We are all the same!

Only, we transmit on different frequencies. You, the amateur radio, should never forget this!
