Naaah....he is just trying to listen to an SSB signal that is moved partially outside the receiver's passband. This will make signals sound extremely tinny and ringing. IF shift is used to move a nearby interfering signal just outside the passband while leaving the desired signal inside. Audio quality is altered a bit to the desired signal but the signal/interference ratio is increased.
