Are you sure that's real noise or just the S-meter reading?  The K3's
S-meter has excellent linearity whereas most other rigs do not (Flex 5000
excluded).  S2 on the K3 is about -115 dBm and S2 on a FT-1000 is -102 dBm. 
So the K3 will show correct readings at a level where the typical S-meter
will indicate nothing.  Said another way, a weak noise signal of -115 dBm
will not register on an FT-1000's meter but the same signal will register S2
on the K3.
