Comment (by FranceBB):

 Using gsar to modify the header also works and makes the files possible to
 decode like so:

 type "INPUTFILE" | C:\temp\gsar.exe
 -s:x83:x09:x40:x00:x00:x00:x02:x80:x01:x03
 -r:x83:x09:x40:x00:x00:x00:x02:x80:x01:x02 -F  | C:\temp\gsar.exe
 -s:x60:x0D:xC0:xDE:x00:x00:x02:x80:x01:x02
 -r:x60:x0D:xC0:xDE:x00:x00:x02:x80:x01:x03 -F > "OUTPUTFILE"

 Still, I believe this should be addressed anyway without using gsar.
