[Elecraft] K3S DSP Filter Plots

[Fred Jensen]

I believe there's more than one correct answer.  In earlier times, the 
"Collins Standard" was 6 dB/S-unit and 50 uv = S9.  My 75S3 came in at 
53 uv for S9, and pretty much held to the 6 dB/S-unit below that.  Not 
so much above S9

With my service monitor feeding my K3, it is exactly 50 uv = S9 because 
I set it for that.  It's a little hard to tell on the bar graph S-meter, 
but it seems to be about 5 dB/S-unit below S9.  It also seems to be 
about 5 dB/S-unit above S9 [i.e. quite linear, in the logarithmic sense 
:-)].

I've often wondered why S-meters go above S9 which should be about the 
strongest signal you ever receive and thus would be full scale.
