I've posted this on the Beta board as it might be considered 'sensitive' by SBS-1 users :-) It might also be a function of the Beta software output.
There is a nice little routine on the Kinetic forum that reads the recorded .bst files to interpret and display the data. I've contacted the author and he is interested in having a look at the RB rbl files to see if he can produce an RBLChart version.
http://www.kinetic-avionics.co.uk/forums/viewtopic.php?t=10562I sent him a sample rbl file, but he has identified that there are data lines with the same time for the same aircraft, but showing slighty different information. Here are a few lines I've copied from an rbl file I've just made. His question of course is "Which line do I read?" which is a perfectly valid question.

I've attached the extract from the rbl file I sent to the BSTChart author below. He's highlighted some of the duplicates in green.
