The amateur radio station operator shall ensure that:

This rule directly reflects international regulations designed to keep amateur radio a purely personal and technical hobby. Operators must ensure their international contacts consist only of remarks regarding amateur radio itself or personal conversations. Any form of commercial communication, no matter how brief, is strictly prohibited on amateur bands. Furthermore, operators are never allowed to charge any amount of money—even a 'nominal sum'—for passing messages, as this violates the core non-pecuniary nature of the amateur service. You also operate under the power limitations of your own country's license, not the foreign administration's rules, making that distractor incorrect.
