[hpsdr] Perseus is a reality

[wbr_wf4r]

Hello All,
              I'm not  a math whiz by any stretch of the imagination, but
I'm wondering why in the beautiful panel layout that there are buttons to
select the sampling rates of 125K 250K and 500K when the sdr only covers
10KHz to 30MHz?  What does this do for the user?  Should the sampling rate
be changed depending on the *displayed*  bandwidth?  Or is this a given.  I
assume that the overall sampling rate will be approximately 60 MHz which
would be the Nyquist rate.  Maybe I just don't understand the labeling
"Sampling Rate"

73, Bill, wf4r
