A familiar voice from the next town. A new one from another country. Both can come through the same CB radio. Making long-distance radio contacts is known as DX, and on the 11-metre band, part of the fun is finding out where your signal can reach.
What makes a distant contact possible?
Most CB conversations are local. When conditions are right, though, the ionosphere can bend radio signals back towards Earth far beyond the horizon. Operators often call this skip. A frequency that sounds quiet in the morning might carry voices from hundreds or even thousands of miles away later in the day.
Conditions change, and signals can fade just as a conversation gets going. That’s part of the appeal. A contact might last only long enough to exchange callsigns, locations and signal reports, but it can be one you remember for years.
Start by listening
If you’re curious, try an online radio receiver or listen on a CB set you already have. Notice how operators take turns and how they give their callsigns when signals are weak. Listening also helps you recognise when the band is opening up and when a frequency is already in use.
When you’re ready to transmit, start with a CB radio and a suitable antenna, and check the operating rules where you live. Listen for a clear frequency, keep your first call brief and speak at a steady pace. It’s perfectly normal to ask someone to repeat a callsign or location.
Keep a record of who you hear
A simple log can start with the date and time, the frequency, the other operator’s callsign and location, and a signal report. Over time, those entries can help you spot patterns, such as which parts of the world you hear at different times of day.
Some operators also exchange QSL cards to confirm a contact. A printed card or digital eQSL can be a keepsake from a conversation that lasted less than a minute.
Explore the hobby with Delta Tango
The Radio DX Knowledge Centre has a beginner’s guide and articles on propagation, antennas and operating etiquette. You can also explore the Activation Archive & DX Map, browse the QSL gallery or meet other operators in Delta Tango Radio Chat.
If you’re starting from scratch, spend a few minutes listening and jot down the most distant station you hear. That’s your first entry in a listening log.
