    hi all, so i have been trying to make a simple metal detector, i find on the internet with clalculator and am radio. Calculator broadcast EMW when is close to metal and am radio picks them up and amplifies them. Thing is i dont have am radio and cant find anywere to buy it, so is there a way to pick up that waves from calculator and to hear them on the speakers or headphones? sry ignorance of electronics and my bad english.
