Thanks to all for the info.
Wiring the XLR for the mike;
pin #1 as ground/shield,
pin #2 mike high,
pin #3 as mike low.
To the radio 8 pin connector;
pin #1 as mike high,
pin 7 as mike low,
pin #8 as ground.
For what its worth, I use a three conductor shielded cable and thus
shield is connected at one end only.

Assuming there has been no change from the late K3, pins 7 and 8 are
both connected to circuit board common. Since the K3/K3S front panel
mic jack is generally compatible with Kenwood (except for the reversal
of pins 5 and 6), most folks treat pin 7 as mic return and pin 8 as
shell/ground/chassis.

While I don't have my new K3S radio yet, I did print the Owners Manual.
It shows the MIC audio connection to be pin #1 as MIC audio, pin #7 as
GRD, and pin #8 as GRD. My question, are pins #7 & #8 the same or is
one analog ground and one chassis. ground. If so, which is analog ground
and which is chassis ground? I'm making a mike cable XLR to 8 pin.

The Heil PR-781 is grossly overpriced. Any quality dynamic mic will
work very well with the K3/K3S.
Right on both counts. Because I'm retired from pro audio, I have a
closet full of pro mics. All of the dynamic mics work very well with
the K3. Before one of the guys in our club introduced me to the CM500,
I used an RE11 on a boom stand from my music recording stash. I also
own two Sony MDR7506 headsets, which I no longer use in the shack
because the CM500 is so good.
The TX EQ built into the K3 is quite capable, and is all that is
needed to tailor TX audio to a mic and a voice. An external equalizer
is a waste of money. All it takes to use any dynamic mic with a K3 or
K3S is a suitably wired connector or connector adapter cable. For a
pro mic with an XL-connector, wire pin 2 to the mic input, pin 3 to
mic return, and pin 1 to the connector shell. Or if you have a two
wire cable (center plus shield), wire pin 2 to the center conductor
and to mic input, tie 1 and 3 together to the shield, and connect to
the K3 connector shell.
