We put the whitener and CRC32 in for a reason:
1) clock recovery and other things work better if you do not have long
runs of 1's or 0's.
2) How will you be able to check end to end integrity without CRC or
other style checking?
The answer is, you can live without either but you pay the obvious
penalties implied by 1 and 2 above.

Even if ggmsk-test were fixed to use it, it doesn't work anywhere
nearly as good as the new code.
I would like to use the new code in gmsk2 but I can't implement the CRC32
and the whiten/dewhiten in the microprocessor used in the transmitter. The
original engineer on this project, who left the company and that I am
replacing, selected a real poor microprocessor.
Do you think that I can use the same basic idea of the gmsk2 framer and
sync whithout the use of the CRC32 and whiten?
