I'm using an LM395 (High reliability transistor) as a simple threshold detector. The source is half wave rectified AC (from a current loop) and through a resistive divider into the gate via a 5K resistor to prevent oscillation (per datasheet).
The saturation point seems very non-linear as I vary the pot. Coule the diode be the culprit ?

Because GMSK is a constant amplitude signal, the power of the modulated signal is constant. Because of that, you can use a compressed, non-linear amplifier for GMSK.

non-linearity per se isn't necessarily an advantage nor a disadvantage. There are some filters that simply perform specific tasks better than linear filters. Examples:
Median Filter does a good job
of eliminating outliers.
Rate Limiter does a good job of
eliminating certain kinds of noise.

basically yes, but the real answer is more complicated. As you have a non-linear circuit, affecting the fundamental, will affect the harmonics. Probably there will be difference in harmonic content between shorting (series resonant circuit to ground) the fundamental component or impeding it (via a parallel resonant circuit in series).

I know there are manual methods through which this can be done, but I prefer not to spend too much time learning them, if it can be done directly using software.

The quoted discussion refers to a very general mathematical field of function theory and linear mappings. If you want to understand XOR in this relation, you would need to get familiar with some theories, I think. If you just want to understand which property of binary logic operations is addressed with "linearity", there's a more simple answer.
