Sometimes, some radio works well when a person stands near it. And starts having problems when there's noone nearby the receiver. What is this effect called? Why does it happen?
And i want to build a FM/AM radio(i know it's not worth really), how components different between the 2 of them(AM/FM)? How do they vary in components?
