Should work as expected if you increase the gain of the microphone amp: https://groups.io/g/BITX20/message/24437
Assume you raise the signal coming out of the microphone amp by 3dB (double the power). Assume the diodes conduct pretty severely on any voice peaks, and reduce them by a factor of 2, so your peak power into the crystal filter is back down to where you started out. But the quieter parts of your voice (for those of us that have any) have not been clipped back, and remain at twice the power.
