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?

73,
Paul N1BUG
