Prepend "lms:" for easy/quickly categorization of scope of the patch. Something like:

lms: Change scaling factor from .3 to .7 to improve signal slope

PS1, Line 31: // this was 0.3 before - values above 0.8 give more phase noise, values below 0.6 give too much amplitude resolution/noise to pass gmsk validation on a E4406
We usually use /* */ type comments. No need to specify it was 0.3 before, we have git log for that ;)

Probably add word "experimentally found" or similar to understand it doesn't come from some spec sheets from producer.
