Steve,

The only thing I can say is that there is more than enough audio drive 
with my MH3 microphone.
Does your MH-31 work with plenty of audio on your FT-817 or FT-857?

My numbering scheme was consistent with a left to right convention 
looking into the jack opening (like the diagram in the FT-817 manual.  
If you were looking at the end of the plug, the numbers would be reversed.

73,
Don W3FPR
