Administrative Regulations on the Establishment of Radio and TV Broadcast Station Article 9

The transmission power and transmitting field strength of transmitter for each type of station are stipulated as follows:1. For amplitude-modulated radio stations:（1）The transmission power of transmitter for Type A AM radio station shall be 3 kW or lower. The field strength of ground wave beyond a radius of 40 km from the transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for transmission field strength is not a true circle, the widest point-to-point distance, referred to as the widest radial length hereinafter, of the station transmission antenna through which the field strength mentioned in the preceding paragraph passes shall not exceed 80km.（2）The transmission power of transmitter for Type B AM Broadcasting station shall be 5 kW or lower. The field strength of ground wave beyond a radius of 60 km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission is not a true circle, the widest radial length of field strength mentioned in the preceding paragraph shall not exceed 120 km.（3）The transmission power of transmitter for Type C AM radio station may be greater than 5 kW. The field strength of ground wave beyond a radius of 100 km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission isn’t a true circle, the widest radial length of field strength mentioned in the preceding paragraph shall not exceed 200 km.（4）Output electric power of transmitter and field strength of transmission for other type and overseas AM radio stations shall be stipulated by the competent authority depending on practical situations.2. For frequency-modulated radio stations:（1）The transmission power of transmitter shall be 1.5 kW or lower for Type A FM radio station in Yilan, Hualien, Taitung（hereinafter referred to as Eastern）and offshore islands, and 750 W or lower for the rest of regions. The field strength of ground wave for Eastern and offshore islands beyond a radius of 15km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission is not a true circle, the widest radial length of field strength mentioned above shall not exceed 30km; field strength of ground wave for the rest of areas beyond a radius of 10km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for electric field intensity of transmission is not a true circle, the widest radial length of field strength mentioned in the preceding paragraph shall not exceed 20 km.（2）The transmission power of transmitter for Type B FM radio station shall be 3 kW or lower. Field strength of ground wave for Eastern and offshore islands beyond a radius of 30km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission is not a true circle, the widest radial length of field strength mentioned above shall not exceed 60 km; field strength of ground wave beyond a radius of 20km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission is not a true circle, the widest radial length of field strength mentioned above shall not exceed 40km.（3）The transmission power of transmitter for Type C FM radio station shall be below 30kW. The field strength of ground wave beyond a radius of 60km from transmitting antenna shall not be greater than 500 μV/m or 54 dBμV/m. If isotropic curve for field strength of transmission is not a true circle, the widest radial length of electric field intensity mentioned in the preceding paragraph shall not exceed 120 km.（4）The transmission power of transmitter and transmission field intensity for other types of FM radio station shall be stipulated by the competent authority depending on the practical situations.3. The transmission power of transmitter shall be 10 kW or lower for wireless television stations. The intensity of the transmission field shall be stipulated by the competent authority depending on the practical situations.For the stations mentioned in the preceding paragraphs, if it is deemed by the competent authority necessary for broadcasting management or in case of electric interference that shall be resolved by adjusting transmission power, the transmission power and transmission field strength may be adjusted by the competent authority at the authority’s discretion; Interference resulted from transmission power adjustment shall be resolved through negotiation. The failure to resolve the interference may be brought to the attention of the competent authority and resolved in accordance with the competent authority’s concluded decision.
