U0101. The essential technical measure for an amateur repeater is:
业余中继台必备的技术措施为：
Exam tips · 考试提示
A repeater must have a responsible monitor/manager, effective
remote control, and the ability to stop transmitting promptly if it causes harmful interference (A). Encryption to restrict use (B),
cranking up power to override others (C), and hot-standby (D) are
not the required measure and some are contrary to amateur principles.
U0102. A group has lawfully established an amateur repeater. The correct
practice is:
某团体依法设置了一部业余中继台。其正确做法是：
Exam tips · 考试提示
An amateur repeater must serve all amateurs in coverage equally
and publish its parameters (A). Restricting to permitted users (B), member-priority (C), or charging fees (D) violates the equal-service
principle.
U0103. The principle for choosing the same-band transmit/receive offset
of a 144 MHz or 430 MHz analog FM amateur repeater is:
选择144MHz或430MHz业余模拟调频中继台同频段收发频差
的原则是：
Exam tips · 考试提示
Repeater offsets follow the amateur standard: +/−600 kHz on 2 m (144 MHz) and +/−5 MHz on 70 cm (430 MHz) (A). Non-standard
offsets to exclude users (B), changing offsets (C), or arbitrary
selection (D) are not the principle.
U0104. The radio transmitting equipment used by an amateur radio
station must meet the following conditions: (Choose all that
apply.)
业余无线电台使用的无线电发射设备必须符合下列条件：
Exam tips · 考试提示
Equipment must be compliant: commercial gear needs type approval covering amateur bands (A), and homebrew/modified
gear must meet national standards and stay within amateur bands (B). Unrestricted homebrew (C) and "foreign gear just needs
international standards" (D) are wrong — China requires its own
type approval.
U0105. "I am not an amateur radio operator; I applied for a station just
for driving convenience and don't need to follow amateur radio
rules." This statement:
The statement is wrong (A): establishing a station requires being
familiar with radio regulations, and an amateur station may only be
operated for its statutory purpose by qualified persons. Personal "driving convenience" is not a basis to ignore the rules. B/C/D
wrongly excuse non-compliance.
U0106. An amateur operator hears what is clearly man-made interfering
transmission from a non-amateur station on an amateur-only
frequency, and presses the microphone to lecture that transmitter
about radio regulations. The correct comment on this behavior is:
Even in response to interference, an amateur station may only be
used for intercommunication, technical research, and self-training — broadcasting a regulatory lecture is outside that scope (A).
Options B/C/D wrongly call the action correct.
U0107. Retransmitting broadcast stations, internet chat, telephone calls,
or other stations' contact signals through an amateur radio
station — the nature of this behavior is:
在业余无线电台中转发广播电台、互联网聊天、电话通话、其
他电台的联络信号，这类行为的性质是：
Exam tips · 考试提示
Rebroadcasting third-party content (radio, internet, phone, other
stations' traffic) is prohibited because the information origin is not
an amateur station, violating the statutory purpose (A). B/C/D wrongly excuse it.
U0108. An amateur station relays messages for other persons, units, or
organizations during communication. The correct comment on
this practice is:
业余电台在通信中为其他人或者单位、组织转达信息。对这种
做法的评论应该是：
Exam tips · 考试提示
Relaying messages for third parties is illegal because it goes beyond
the amateur station's permitted purpose (A). The content, being free, or being "public-interest" (B/C/D) does not make it lawful —
the statutory-purpose limit is what matters.
U0109. An amateur radio association broadcasts public-interest notices
and technical-training lectures to its members during
transmissions, but without the approval of the relevant radio
management authority. The correct comment on this practice is:
Broadcasting or transmitting broadcast-type (通播) signals without approval is prohibited (A). The beneficial intent — skills, emergency
training, or regulations publicity (B/C/D) — does not excuse the lack of approval.
U0110. The correct practice regarding the language used during amateur
radio communications is:
关于业余无线电台在通信过程中使用的语言，正确的做法为：
Exam tips · 考试提示
业余通信应使用明语 (plain language) 或业余无线电领域公认的缩略 语、简语 (abbreviations/shorthand recognized by the amateur
radio community). Self-created codes, jargon intelligible only within
a clique, or rare languages meant to exclude others all violate the openness principle of the amateur service. Only A conforms.
