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.
