If you want to be quick in a contest or simply want to know where a call sign comes from, you have to know prefixes. PrefixPlay makes learning amateur radio call sign prefixes a game.
Why learn prefixes?
Every amateur radio call sign begins with a prefix that reveals the country. When you hear “UA3…” you immediately know: Russia. “VK2…” means Australia. This knowledge is essential for:
- Contests – Quick recognition saves valuable seconds
- DX Hunting – Know immediately if this is a rare DXCC
- General radio operations – small talk via the other person’s QTH
- Exam preparation – Prefixes are exam material
How does PrefixPlay work?
PrefixPlay shows you callsign prefixes and you have to select the correct country – or vice versa. The more you practice, the faster you will become. The whole thing is playful, with direct feedback on your answers.
There is also a prefix overview (DXCC list) in which you can look up all prefixes – practical as a reference during radio operation.
Features
- Quiz mode for practice
- Complete DXCC prefix list as a reference work
- Works in the browser, no installation required
