**below curtesy of Brian Lusk KC0YEJ**
I'd like to add a few more microphone pinouts to your
charts, if you would like them.

The Kenwood TM-733A 2M/70cm dual-band radio uses an
RJ-45 connector for microphones that is unlike any of
those listed on your site. Here it is:

Sorry, I tried to get this picture to format better but my editor is
having none of it! de w5nig. (edit)

1. Down
2. N/C
3. MIC
4. MIC Gnd
5. PTT
6. Common/PTT Gnd
7. (Possibly) 8v
8. Up


---------------
The Yaesu FT-857D all-mode HF/2M/70cm radio uses a
different pinout as well. Using the same RJ-45 as
above, here is this pinout:

1. Down
2. Up
3. (Possibly) +5v
4. MIC Gnd
5. MIC Audio
6. PTT
7. Common/PTT Gnd
8. Fast (FST) Button
Hope this is of use to you! Sincerely, Brian Lusk KC0YEJ
