Chapter 5 Amateur Station Operation
In the case of an intended addition or change of external RF power amplifier or its kit for an amateur station, the owner shall submit an application to the competent authority. The station shall not be operated until the application is approved and the station license has been renewed. The removal of external RF power amplifier or its kit from an amateur station shall adhere to the Administrative Regulations on the Controlled Telecommunications Radio-Frequency Devices and the owner shall apply to the competent authority for the renew of station license.
The external RF power amplifier or its kit mentioned in the previous paragraph shall comply with the Technical Specifications for Amateur Radio Apparatus.
The call sign of an amateur station shall be assigned by the competent authority on the issuance of the amateur station license. However, the call sign may be assigned directly by the competent authority when the application is made for establishing a temporary station.
No amateur operator shall be allowed to request the assignment of a certain call sign. However, the competent authority may assign the call sign as applied for when the call signs of the temporary station meet the requirement of Article 27 and this does not cause duplicate assignments.
When having obtained the qualification for a higher class, the amateur operator may apply to the competent authority for changing the call sign of the originally established amateur station.
Once the call sign of the aforementioned amateur station has been reassigned, the former call sign shall be returned and shall no longer be used.
The combination of amateur station call signs shall comply with the followings:
1. The alphabet letter ‘Ｂ’ shall be used as the first character.
2. The second character shall be selected from the alphabets letters Ｍ, Ｎ, Ｏ, Ｐ, Ｑ, Ｕ, Ｖ, Ｗ and Ｘ.
3. The third character shall be a numeral representing the municipal, country or city where the amateur station is located, or a temporary station. The selection shall be as follows:
（1）０: Temporary station.
（2）１: Keelung, Yilan.
（3）２: Taipei, New Taipei.
（4）３: Taoyuan, Hsinchu.
（5）４: Miaoli, Taichung.
（6）５: Changhua, Nantou, Yunlin.
（7）６: Chiayi, Tainan.
（9）８: Pingtung, Taitung, Hualien.
（10）９: Any other areas outside the island of Taiwan.
4. The fourth through sixth characters consist of a set of 3 or fewer alphabet letters grouped based on the number of alphabet letters in the set as follows:
（1）One-character set: indicates a special amateur station; or a repeater station if the second character of the call sign is Ｘ;
（2）Two-character set: indicates a Class 1 amateur station;
（3）Three-character set: indicates a Class 2 amateur station if the second character of the call sign is Ｘ, and Class 3 amateur if the second character of the call sign is any other alphabet letter.
The combination of temporary station call signs is free from the limits specified in subparagraph 4 of the previous paragraph. In the case where a temporary station is established for a memorial purpose, the combination of its call sign may also be free from the limits specified in Subparagraph 3 of the previous paragraph on condition that numerals shall be used for the third and fourth characters.
In the case where a non-domestic amateur radio group or a person is approved by the competent authority to operate an amateur station for a short period of time within the territories of Republic of China, a back slash shall be used as the third character of the temporary station call sign.
A special amateur station, when approved by the competent authority, may use the call sign combinations for temporary stations mentioned in the three previous paragraphs to assemble its call sign.
The amateur operator shall transmit its assigned call sign on the transmitting channel of the station at the beginning of each communication, at the end of each communication, and at least every 10 minutes during communications.
The rules for amateur station's identification and call sign are provided as follows:
1. For voice communications, the language of English or the identifiers provided in the International Radio Regulation in English shall be used.
2. For data transmission and spread spectrum communications, the code specified in Article 30 of these Regulations shall be used.
3. The call sign shall be clearly shown in English on picture（s）in image transmission.
4. When an amateur operator operates a station whose class is equal to that of the license class of the operator, the call sign of the operating station may be used.
5. When an amateur operator operates a station whose class is below that of the license class of the operator, the call sign assigned to the control operator's station shall be added after the call sign of the station where the operator is operating with the back slash mark between the two call signs so as to identify.
One of the following required data code operation modes shall be used when an amateur operator transmits radio teletype or data via an amateur station:
1. The No. 2 5-unit RTTY codes defined in International Telegraph and Telephone Consultative Committee recommendation CCITT F.1, Division C（i.e. the Baudot Codes）;
2. The 7-unit codes specified in International Radio Consultative Committee recommendation CCIR 476-2（1978）, 476-3（1982）, 476-4（1986）or 625（1986）（i.e. the AMTOR Codes）;
3. The expanded 7-unit codes provided in No. 5 international alphabets defined in International Telegraph and Telephone Consultative Committee recommendation CCITT T.50, or X3.4-1977 defined by American National Standards Institute（ANSI）, or ISO 646（1983）by International Standardization Organization and CCITT recommendation T.61（Malaga-Torremolinos, 1984）（i.e. the ASCII codes）;
4. J2D type data communications.
Amateur operators shall submit a memo to the competent authority for the use of a data code operation mode other than any of those specified in the previous paragraph for radio teletype or data transmission.
Amateur operators shall comply with the requirements in the applicable administrative regulations on amateur radio when operating an amateur station. The competent authority may require an amateur operator to take the following measures when necessary:
1. Cease using any data code operation mode other than those specified in the previous paragraph for radio teletype or data transmission;
