Subelement T1, COMMISSION’S RULES· Group T1B · 47 CFR §97.303
How are US amateurs restricted in segments of bands where the Amateur Radio Service is secondary?
- A.U.S. amateurs may find non-amateur stations in those segments, and must avoid interfering with them (correct answer)
- B.U.S. amateurs must give foreign amateur stations priority in those segments
- C.International communications are not permitted in those segments
- D.Digital transmissions are not permitted in those segments
WhyIn band segments where the Amateur Radio Service is secondary, U.S. amateurs may share the segment with non-amateur stations but must avoid interfering with them. §97.303 governs bands where amateur radio is a secondary allocation, meaning another service has primary rights there. Secondary users must not cause interference to primary stations and must accept interference from them, so hams operating in those segments have to watch for and avoid stepping on non-amateur stations, answer A. B, C, and D all invent restrictions the rule doesn't actually impose.
