[Elecraft] K3S DSP filter plots

[Bob McGraw - K4TAX]

Here is a site that provides free computer based spectrum displays. I 
use Spectrum View in conjunction with the USB soundcard within the K3S.  
It can be run in real time and you observe the changes that occur as the 
various parameters of BW and Shift are utilized.  Easy to use and best 
of all, its FREE!

With this application one can see the effect of the BW and Shift 
changes.  Also with the markers, one can measure, with reasonable 
accuracy and repeatability, the results between different configurations.

I'm sure there's other applications. This one just happens to be one of 
my favorites and thus I don't move the HP Spectrum Analyzer from the 
shop to the station.  {By the way I figured out what HP stands 
for............it's "Hernia Producing"}
