[hpsdr] Mercury v2.4 -- still distorted audio ( Atom 330 ) Corrected.

[W4sc]

CORRECTED:  Should read

W4EFZ and I had Mercury/PwrSDR and SDR-IQ/Spectraview running, and
cruising internet, all at same time on his Atom330, no problems.  CPU
loading was about 55% or so.

Thanks Joe,, I was dreaming about Penelope at that moment when the fingers 
were in motion.
