[Elecraft] RX Test (long)

So what you are saying is the K3 is too quiet for its own good, and that's what makes it so noisy!

However, the stopband also has 
many leakage products (DAC artifacts) in the stopband some 
of which are as much as 50 dB ABOVE the noise floor.  

While these products are well below the desired audio in the 
passband, they are "in the clear" as far a local noise.  
This requires the ear/brain system to subconsciously work 
to reject (filter) the undesired discrete frequency products.
