[Elecraft] Is the K3 have low sensitivity on 10 M and 6 M

I have always done the same thing with signals at the noise floor, or below. The biggest change I've noticed by doing this is the band noise is much more attenuated through the headphones lying on the table and the signal one is trying to copy jumps out in the clear since band noise is attenuated.

Related subject:  An old CW RO's trick when copying a weak signal in 
noise and QRM is to lay the headphones on the desk face up.  I learned 
this years ago on the Holy Frequency.  I have no idea why it works, but 
it often does.  Maybe one of the acoustic experts here will explain it.
