3.4 تعديل الإسكات

The squelch control on the rear of the receiver helps to suppress unwanted noise when the transmitter signal is weak or absent. Adjust the "SQ" knob for each channel. A higher squelch setting requires a stronger signal to open the audio gate, reducing background noise but potentially cutting off weak signals. A lower setting allows weaker signals but may introduce more noise.
