Under what condition are you permitted to use a new digital encoding technique that you developed to transmit data over amateur radio bands?
- A When it includes sending the amateur radio station's call sign
- B When it is published in the public domain
- C When it is used for music streaming content
- D When it is used for commercial traffic
Correct answer: B — When it is published in the public domain. From the official ISED question bank, verified word for word.
Why
You may use a new digital encoding technique you developed only when it is published in the public domain, meaning the details are freely available for anyone to study and use. The full explanation — and one for every question — is in Pro.
