In the 'IGC File Name Decoding Made Easy' it was mentioned
about the EW
Avionics recorders (and other recorders) which take
a long base10
serial number and convert it to base36 (0-9, a-z) to
fit in the file
name format.

'Cambridge, Garrecht (Volkslogger), Zander all use
the external serial.
Filser,LX,Colibri,PrintTechnik convert external serial
directly to
base36' - Peter Wyld

Peter also comments that depending on the Model of
EW recorder, they
take the serial number on the case and add 2000 (B
models) or 9000(D
models). A models stay the same. Whew.

What about the Model C? I don't think there were many
of these, but I
believe there were some.



Model EWC - add 6000 (range 6001-8999, 4MP-5EF)
Model EWF - add 5000 (range 5001-5999, 3UX-4MN)

I have an Excel spreadsheet which converts logger serial
numbers to the b36 part of a filename. It's pretty
ugly, but you're welcome to it if you want it.
