If an amateur repeater's transmitter is activated by intermittent interference with unclear voice, and monitoring by other amateur radio stations within the coverage area confirms no station is operating on the repeater's uplink frequency, it is likely that strong signals from two other transmitters near the repeater are causing intermodulation interference on the uplink frequency.
如果业余中继台发射机被断断续续的干扰信号所启动,夹杂着不清楚的语音,根据覆盖区内其他业余电台的监听,确定中继台上行频率并没有电台工作。则可能是中继台附近的两个其他发射机的强信号在中继台上行频率造成了互调干扰。
