Thank you for your interest and quick reply. 

Its a great start, seeing as I'm a beginner with python, I was actually hoping to see an example of http://code.activestate.com/recipes/408859/ as it appears to be exactly what I need, but I haven't got a clue how to implement it. Basically as each byte perhaps gets read or 9 bytes at a time, that way I can seek out as much real data as possible

Data:  [0000002c025b025321]
Data:  [00010048000602505e]
Data:  [0002004a000a025552]
Data:  [0003004b0006025752]
Data:  [00046698000702569e]

(notice the header data[9:1] will always flow in this pattern 0 -> 4 and then back again, so I figure that might as well be my start)


And skip the errors...

Data:  [0002004b000a026343]
Data:  [00]
Data:  [03004f0006025b4a00]
Data:  [046698000802569d00]
Data:  [00003002830257f100]
