Here is the problem I am having. Notice the calculated time offset:
http://www.n1bug.com/eb1.jpg
If I run EbNaut-rx with that I get:
http://www.n1bug.com/eb2.jpg
If I edit the time in EbNaut-rx to 160.95 s and run it I get this:
http://www.n1bug.com/eb3.jpg
Is the last decoder output correct?
What could be causing the time calculation problem?
