Reception of a station in a wrong position is caused by ______

The correct option is 4

Concept:

1) Defective Gang Condenser: In radio technology, a gang condenser is a type of capacitor used to change the frequency of an oscillator circuit. If the gang condenser is defective, it would affect the tuning of the receiver, but this failure would likely cause the radio not to receive any stations at all rather than receiving a station at the wrong position.

2) Misalignment of I.F.T (Intermediate Frequency Transformer): This is an essential component in the radio's superheterodyne receiver design, which assists in converting received signals to a lower, fixed intermediate frequency (IF). Misalignment of this component may lead to distortion or loss of signals, but it usually would not cause the radio to pick up a station at the wrong position.

3) Misalignment of Antenna Coil: The antenna coil is linked to the radio receiver's input, which captures the radio waves. If the antenna coil is misaligned, it could potentially lead to poor reception or none at all. Incorrect positioning of stations wouldn't typically result from a misalignment of the antenna coil.

4) Oscillator Coil: Oscillator circuits in a radio generate a signal at a specific, desired frequency. These frequencies are then mixed with the received radio frequency signals, and this process facilitates tuning into different stations. If the oscillator coil is improperly adjusted or not functioning correctly, it could indeed cause the reception of a station at a wrong frequency, essentially the wrong position on the dial, which we usually call "misalignment."
