      Great post. Thanks.

      I appreciate the extra information as I learn a bit more about the SDR topic in general and enjoy playing with the Peaberry I built last month.

      I had a hard time figuring out a few things but with the help of several people on this board it all came together and now I wonder why I was so 'challenged' because it's all rather straightforward.

      Next stop is definitely to play with PowerSDR.
