Hi Stefan

Did you get gpsd and ntp working by following Paul's info (email 21/07)?

I have a UBlox NEO 7M connected to the RaPi by USB and I can run xgps or 
cgps and see that the NMEA is being read. But ntp is not being updated 
by the gps...

Once I have that problem solved and built the PPS shaper, I can make 
progress with the Octo soundcard project.

Paul made it seem so easy...!

I followed your recommendation and bought some of the DC/DC converters 
from Amazon. Do they require any additional filtering?
