小功率发射机在使用过程中因维护不到位、电压不稳定、使用条件恶劣等原因出现一些故障,影响安全播出。下面笔者就发射机播出过程中频繁出现功率波动故障、无法满功率开启发射机或发射信号场强不达标、在某一个特定频段上无法满功率开启发射机等故障展开论述。 Low-power transmitters in the course of their use due to maintenance is not in place, voltage instability, bad conditions and other reasons there are some failures, affecting the security broadcast. The following author on the transmitter broadcast power fluctuations occur frequently, unable to open the transmitter at full power or transmit signal field is not up to standard, in a particular frequency band can not open the transmitter full power failure and other discussions.
