[R-390] sensitivity measurement observation

[Roger Ruszkowski]

Tony,
By definition the limiter is suppose to limit noise.
You would think that by turning it on you would clip 
some of the noise off around the signal and thus get a 
better ratio with the limiter on. How much is not 
calibrated. So to keep thing nuts equal to thing nuts
all advertised results are just done with the limiter
turned off.
