    • A system for detecting and removing undesirable noise, such as beats and tones, from radio signals. The system includes a manual oscillator that is a manually tuned by a user to a selected manual frequency from one of a plurality of frequencies. An electronic oscillator is electronically tuned to a selected electronic frequency from one of the plurality of frequencies. A processor isolates and stores at least one interference frequency associated the selected electronic frequency and determines a correction signal to correct any interference frequencies within a particular selected electronic frequency. The selected manual frequency is corrected using the determined correction signal for the particular selected electronic frequency when the selected manual frequency is the same as the particular selected electronic frequency.
    • 用于从无线电信号中检测和去除不期望的噪声(例如节拍和音调)的系统。 该系统包括手动振荡器,其由用户手动调谐到来自多个频率之一的所选手动频率。 电子振荡器从多个频率中的一个电子调谐到所选择的电子频率。 处理器隔离并存储与所选择的电子频率相关联的至少一个干扰频率,并确定校正信号以校正特定所选电子频率内的任何干扰频率。 当选择的手动频率与所选择的特定电子频率相同时,使用所确定的特定选定电子频率的校正信号来校正所选择的手动频率。
