[Elecraft] Sherwood Receiver Test Data - K3S Added Today

Fred,

Isn't that what the RF Gain control or input attenuator is used for?
The ADC does not simply clip, when it overloads, the ADC output becomes 
total garbage.

In other words, I don't know of any reasonable answer.  To my mind, the 
ADC determines the maximum usable dynamic range.  If the strong signals 
overwhelm the ADC maximum signal levels, no signals can be successfully 
demodulated.

Mathematically, the overload situation might not be considered, but with 
practical devices (ADC), overload is quite possible.
