General exam question G1C07
Subelement G1, COMMISSION’S RULES· Group G1C · 47 CFR §97.309(a)(4)
What must be done before using a new digital protocol on the air?
- A.Type-certify equipment to FCC standards
- B.Obtain an experimental license from the FCC
- C.Publicly document the technical characteristics of the protocol (correct answer)
- D.Submit a rule-making proposal to the FCC describing the codes and methods of the technique
WhyThe technical details of a new digital coding technique must be publicly documented before it's used on the air. §97.309(a)(4) requires that the technical details of a new digital coding technique be publicly documented before it's used on the air, so that anyone monitoring can determine what the transmission contains, consistent with the rule against obscuring a message's meaning, answer C. Type certification and experimental licenses apply to equipment and research, not to publishing a protocol's specification, and no rule-making proposal is required just to use a documented new mode.
