Signal on laptop
Can anyone explain this ?
Sitting in an adjoining room some distance away from my laptop, which was switched on, I heard a bleep then a girl's voice saying, hesitantly, " hello". I went towards the laptop and heard a few indistinct noises then it reverted to it's usual silent desktop state.
I'm reminded of a time, in the 1960's, when my desk dictaphone recorder, connected to the mains, picked up a very clear conversation between two water authority employees.
I can vaguely understand that a wifi connected device can pick up something from the ether but I've never worked out how the dictaphone did.
