Background
The international phonetic alphabet is the same in aviation, maritime and amateur radio: Alfa, Bravo, Charlie to Zulu. It ensures callsigns are understood unambiguously even with weak signals. The RST report rates readability (1–5), signal strength (1–9) and for telegraphy the tone (1–9).
In practice
How it works: start with the phonetic alphabet until you can spell callsigns fluently. Then practise Q codes and procedure words and finally run through whole sequences: general call, directed call, report, sign-off. Speaking aloud helps – in real operation what counts is what is received, not what was meant.
Frequently asked questions
May I practise without a licence?
Yes, the trainer runs in the browser; nothing is transmitted. Transmitting on amateur frequencies requires a licence.
Why Alfa and Juliett spelled this way?
So that speakers of different languages pronounce the words the same way.
