OOPS, Pin 2, not pin 3.
Should be 600 ohms at pin 3 (ext mic). You can get around this by
turning up the mic gain in the programming software.

I am trying to hook one up to use
for an autopatch and cannot get enough drive from the patch to be
useful. I suspect an impedance mismatch.
I don't have any doc for the things
and Moto's web site isn't any help.
Thanks -Rob-
