I  want    to reinforce  what   Ted  Cline said about  why we  want  to use  GNU Radio  in Amateur Radio  Astronomy   in  last GNU Radio  Group  hosted by   Andrew.

GNU  Radio    does the   buffer  management and  scheduling  of  processing  for  us,   A flow  graph sends  data from one  block  to  the next but  who  manages this   coordination for us?   Gnu  Radio  does this for  us  in multiple  processes  using  our  new   multi-core hardware

 Suppose   you  have  data arriving from  your  sdr   at  a  very   fast  rate...  you need  to  buffer it  and  make it  available   to your  collection  software in an  orderly  manner.   GNU  Radio  software will for  do this  for   you.

GNU  Radio uses compiled  C++  code  to  speed up the heavy  lifting  of   digital  signal  processing...  such  as  FFT's   and   Infinite  Impulse  Filters...

It  is  cool stuff    try it.
