Radar receivers have to be tuned to the precise frequency of the transmitter, in order to get the best detection and thus the best picture.
The transmitter generates microwaves from a device called a magnetron. The exact frequency can vary with age and temperature.
To pick up the echo generated from the pulsed microwave, the receiver is able to be tuned, to allow for differences in transmitter frequency.
The control on the radar receiver display, called 'tuning', actually alters the receiver frequency, not the transmitter frequency.
