CRAC Class C (2025) — Questions 1–10

我国无线电管理的基本行政法规是《中华人民共和国无线电管理条 例》(the Radio Regulations of the PRC), enacted by 国务院 and 中 央军委 (the State Council and the CMC). Option A names the correct regulation and C names its enacting authorities, so together they answer both parts of the question. Option B is a non-existent title, and D (MIIT) is the implementing ministry, not the enacting body of this regulation.

我国专门规范业余无线电台的规章是《业余无线电台管理办法》(the Measures for the Administration of Amateur Radio Stations), enacted by 工业和信息化部 (MIIT). Option A gives the correct document and C gives its enacting authority. B is an obsolete/non- existent title, and D (the State Council) is wrong because this Measure is an MIIT ministry order, not a State Council regulation.

依法负责对业余无线电台实施监督管理的机构是国家无线电管理机 构以及省、自治区、直辖市无线电管理机构. This two-tier structure (national plus provincial/municipal radio management authorities) is the official supervisor. Associations, sports authorities, and police departments have no regulatory authority over amateur stations.

The definitions of 业余业务 (amateur service), 卫星业余业务 (amateur-satellite service), and 业余电台 (amateur station) are given in 《中华人民共和国无线电频率划分规定》 (the Radio Frequency Allocation Regulations of the PRC), which contains the Table of Frequency Allocations and the service definitions. The other listed documents regulate administration, telecommunications, or licenses but do not define these terms.

最新发布的《业余无线电台管理办法》 came into force on 1 March 2024 (自2024年3月1日起施行). This is a fixed statutory date that candidates must memorize. All other dates are distractors.

划分 (allocation) is the act of entering a band into the Table of Frequency Allocations for use by one or more services under specified conditions. 分配 (allotment) applies a band to a service in a region, and 指配 (assignment) authorizes a specific station — these are distinct ITU steps and must not be swapped.

分配 (allotment) means specifying that a frequency/channel is to be used by one or more administrations within a designated area for a given service under conditions. It sits between 划分 (allocation, table-level) and 指配 (assignment, station-level).

指配 (assignment) is the authorization of a specific station to use a frequency under specified conditions — the final, station-level step after 划分 and 分配. The other three terms refer to broader or different processes.

When a band in the Table of Frequency Allocations is allocated to multiple services, they are categorized as 主要业务 (primary service) and 次要业务 (secondary service). Primary services have priority; secondary services must not cause harmful interference to, and must accept interference from, primary services.

辐射 (radiation) is energy flowing outward from any source in the form of radio waves. Lightning-generated electromagnetic interference travels through space as radio waves, so it is radiation (A). B is conducted (not radiated) interference along a wire; C and D are confined fields (inductive/capacitive) inside a component, not radiated outward waves.
