What is the purpose of using a receive attenuator?
To prevent receiver overload from strong incoming signals✓Respuesta correcta
To reduce the transmitter power when driving a linear amplifier
To reduce power consumption when operating from batteries
To reduce excessive audio level on strong signals
Explicación
A receive attenuator inserts a fixed loss ahead of the first amplifier stage, keeping strong incoming signals below the point where the front end leaves its linear range and creates unwanted mixing products and desensitisation. It affects only the receive path, so it does nothing to transmitter drive or battery drain.
