You trimmed the part of my post that dealt with the bandwidth issue. 
Why don't you read that again?

Just like Joerg you are applying knowledge of electronics to part of a 
receiver without understanding how it all works together.

Oh, and these receivers typically use a long wire antenna, not the coil, 
to collect the signal.
