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 On 7/26/2012 10:58 PM, Steve KC8QVO wrote: > Don Wilhelm-4 wrote >> Pin 4 goes to the tip >> Pin 5 goes to the shell >> Pin 3 goes to Ring 1 >> Pin 2 goes to Ring 2 >> > Don, > > Your numbering was backwards from what I used, but I translated the numbers > from the other direction (made 8 = 1, 1 = 8, and the others in between to > match) and got the same pin designations and wire colors.
