Welcome to DCO HAM RADIO
About DCO HAM Radio
The DCO HAM RADIO site, run by DX Communication Operators (DCO), is your gateway to amateur radio and SWL (Shortwave Listening). Explore operating modes, antenna concepts, and the many sides of radio technology.
Who We Support?
Whether you're a seasoned ham or new to radio, you'll find insights, tips, and guides to boost your skills. Topics include SWL, QSL cards, contests, and details on many radio bands.
Our Mission
We aim to share knowledge, promote understanding, and inspire radio enthusiasm. From technical research to practical applications, DCO is your partner on the airwaves.
Our Principles
Respect is essential. We will not tolerate arrogance from licensed operators toward those without a license. Times have changed, and cooperation benefits us all.
Working Together
Licensed and unlicensed operators should collaborate, not compete. We don’t interfere with hams, and expect the same in return — the only difference is the frequencies we use.
Activities We Promote
We organize contests, field days, mountain and marine radio events, and help during disasters — offering support to both citizens and authorities.
Important Statement
Let’s be clear: Disrespect from AFU or HAM operators who believe they are superior to unlicensed radio operators will not be tolerated. While some may think they hold more knowledge or tradition, times have changed.
Our focus is to promote radio in all its forms — hosting contests, field days, mountain and marine operations, and assisting citizens and authorities in disaster communication, both personally and through licensing when possible.
Licensed hams and unlicensed DCO members should work together, not against each other. We don’t interfere with amateur operators, and expect the same courtesy in return. In the end, we are all the same — only our frequencies differ. Never forget that!
