What does a receiver's dial calibration depend on?
Answer: A
The dial reads the signal frequency, which is the oscillator frequency less the intermediate frequency, so correct tracking is what makes the calibration true across the band. Padder and trimmer adjustments exist precisely to align it at three points. Audio gain, detector characteristics and loudspeaker impedance have no bearing on which frequency the dial indicates. Alignment is the process of making a mechanical scale agree with an electrical relationship.
