Is it a regular periodic thumping sound?

Is this a battery powered device?

Its not a battery operated device, I play it on 230 Volt /50 Hz commercial supply n it seems problem with FM antenna/Circuit but I cant pin point. Regular periodic thumping sound is not happening,when we tune a FM station, thumping sound will start and when we tune away to a no signal zone ,there wont be any thumping sound.
