Thank
you very much Markus
  
  
  The .USR file is useful, but your detailed explanations are even
better to understand what's going on
  Would worth to add it to your EbNaut utilities
  
  
  So far so good. SL is "armed" and working on the next FFT in a
few hours
  Yes. Patience is a must when you play with high integration
FFTs. This is not a game for nervous players ;-)
  
  
  I was using 192Khz sample rate but have changed to 48KHz to fit
with your decimation and FFT lenght
  The 1pps syncronization is working good and the SR is adjusted
properly. I get the NMEA via com port
  and system is reported by SL to be just few mili seconds from
GPS 
  
  
  All ready here to receive a transmission !
