14. External RF Power Amplifier Kit: A package of electronic parts, which, when self-assembled pursuant to the user's manual, is an external RF power amplifier, even if additional parts are required to complete assembly.
15. Transmitter: Any type of device that is capable of converting electrical energy to electromagnetic energy, including external RF amplifiers, which may be required.
16. Peak Envelope Power: The average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle at the crest of the modulation envelope taken under normal operating conditions.
17. Transmission Power: the radio frequency power generated by an amateur radio station, measured in one of the following methods:
（1）Output Power: Peak envelope power measured at the output terminals of the transmitter.
（2）Effective Radiated Power（ERP）: The product of the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction.
（3）Equivalent Isotropic Radiated Power（EIRP）: the product of the power supplied to the antenna and its（absolute or omni-directional）gain relative to an omni-directional antenna in a given direction.
18. Harmful Interference: Interference, generated by radio communications, which endangers the functioning of a radio navigation service or other safety maintenance services, or seriously degrades, obstructs, or repeatedly interrupts a legitimate radio communications service.
19. Amateur Radio Operations: The radio communications operations conducted by amateur operators for self-training, mutual communications and/or technical research.
20. Broadcasting: Transmissions intended for reception by the general public, either directly or by relay.
21. Emergency Communications: Radio communications service established for protecting the safety of human life and preserving property under emergency situations.
22. Amateur Radio Station: A fixed or mobile station in an amateur radio service consisting of the apparatus necessary for conducting radio communications; referred to hereinafter as an amateur station.
23. Group Radio Station: A fixed amateur station set up by an amateur radio group.
24. Temporary Radio Station: An amateur station established for a short-term period of amateur radio operations for a specific purpose with the approval of the competent authority.
25. Radio Beacon Station: An amateur station transmitting communications for the purposes of observation of propagation and reception or other related experimental activities.
26. Repeater Station: An amateur station that automatically relays signals from other radio stations.
27. Space Station: An amateur radio station located more than 50 kilometers above the Earth's surface.
28. Earth Station: An amateur station located within 50 kilometers of the earth's surface and intended for communications with space stations or with other earth stations by means of one or more other objects in space.
29. Remote Control Station: An amateur station that is indirectly operated by a remote facility through a control link.
30. Telemetry Station: An amateur station that uses amateur radio to transmit far-distant telemetric signals for observation and experiments.
31. Tele-command Station: An amateur station that uses radio communications for the transmission of signals to initiate, modify or terminate functions of a space station.
32. Control Operator: An amateur operator designated by the licensee of an amateur station.
33. Frequency Coordinator: An entity, recognized by the control operators of amateur or repeater stations, that recommends transmit/receive channels and associated operating and technical parameters for such stations.
34. Control Point: The location at which the control operator function is performed.
35. Local Control: The operation where radio communications are adjusted and controlled at a station in situ.
36. Remote Control: The operation where radio communications are adjusted and controlled indirectly through a control link.
37. Automatic Control: The operation where radio communications are automatically adjusted and controlled by the equipment and procedures set up by a controller.
38. Third Party Communications: A message from the control operator of an amateur station to another amateur station control operator on behalf of a third party.
39. International Morse Code: A telegram（dot-dash）code as defined by the International Telegraph and Telephone Consultative Committee; referred to hereinafter as the "Morse Code".
