Under what circumstances are messages that are sent via digital modes exempt from Part 97 third-party rules that apply to other modes of communication?
The correct answer is A: Under no circumstances. Messages sent via digital modes are never exempt from Part 97 third-party rules that apply to other modes of communication. Digital modes must follow the same third-party restrictions as voice or other modes. For amateur radio operators, this ensures consistent application of third-party rules regardless of mode. Understanding this helps ensure legal operation when handling third-party traffic via digital modes.
Exam Tip
Digital mode third-party rules = never exempt. Think 'D'igital 'M'odes = 'D'oesn't 'M'atter - rules apply. Third-party rules apply to digital modes just like other modes. No exemptions for encryption, non-encryption, or automatic control.
