HAM Radio tips
HAM operators worldwide use the NATO alphabet for callsign identification and Q-code message exchange.
For DX (long-distance) contacts where signals are weak, phonetic spelling ensures your callsign is logged correctly.
Some operators use creative variants ("Italy" for I, "Spain" for S). NATO is the cross-language standard.
