This is really good information, Alan, and makes sense. Regarding the approximation to Gaussian noise... given that most signals on a crowded band during a contest are highly compressed (their peak-to-average ratios are much smaller) would this make matters better or worse for the ADC, or no difference? I think I read that some signals during a contest have PAR's of 1 dB.
