A few months ago i was at work listening to the radio, which is on a desk about 3 meters away from me. Suddenly it stopped and i heard white noise. I thought the antenna had moved to i walked towards the radio. When i got near it, it suddenly started playing music again. But the nearer i got the more white noise it produced. When i held my hand right above it (few inches) it would only make white noise, and the moment i removed my hand it would play music again. I tried this about 20 times and then a colleage also tried it, but his hand had no effect at all (the radio kept playing music). In the past few months this has happened half a dozen times. The radio would be fine and in a splitsecond it stops. I do not have a watch on my wrist nor any other electronic devices or metal on me. What is the explanation for this?
