Regulations Governing the Use of Radio Frequencies Article 39

The following circumstances shall be deemed as illegally using radio frequency to interfere with legal radio communications:1.Use equipment of legal radiocommunications system to receive perceivable sounds or images of illegally used radio frequency;2.Use measuring equipment to measure identifiable messages of illegally used radio frequency, which can affect system operations, in the legal radiocommunications system;3.In more than five different points within the transmission radius of the antenna of radio stations, the electric field strength between illegally used radio frequency and legal station exceeds any of the following standards: 34 dBuV/m (decibel microvolts per meter) for a co-channel; 48 dBuV/m for a first adjacent channel; 64 dBuV/m for a second adjacent channel; or 74 dBuV/m for a third adjacent channel4.The electric field strength of illegally used radio frequency has been measured using the equipment of the National Communications Commission’s fixed monitoring station, where the electric field strength of frequency between 9 kHz and 174 MHz exceeds 80 dBuV/m, or that of frequency between 174 MHz and 3 GHz exceeds 94 dBuV/m.
