Ok, I was trying to stay away from a pre-amp. What setup does the
Elecraft pro headset have, and how would it have to be wired in relation
to the use of the MH2?

Dave,
Since your plan is to use both the MH2 and the Heil headset with the
HC-5 element, I strongly recommend that you jumper the K2 mic
configuration header for the MH2 - all pins jumpered straight across
(use the little configuration jumpers for computer headers) and solder a
5600 ohm resistor across pins 1 and 6 of the mic jack.
You might also consider connecting the headphone audio to pin 5 of the
mic jack - leave the jumper off the header pin 5 and connect the audio
to the header pin marked "5" with no connection to the pin marked "FUNC"
Then for the Heil headset, build a preamp/adapter in a small external
enclosure - the headset plugs into the adapter. You will need a preamp
to successfully use the Heil HC5 element.
I have a schematic (it is a bit cluttered, but usable) for a preamp that
was designed just for that application - unfortunately I cannot attach
it to the reflector post, so I will send it to you separately.

I have a Heil headset that I purchased about 4 years ago. I'm not
sure if it is the "pro" or not. As memory serves, at the time, the
next step up had a dual element with a switch. The headset has an
HC-5 element. I have an adapter to this to connect to my recently
sold, since finishing my base K2, Kenwood TS-570D(G). I have also
purchased an MH2 microphone.
The original plan was to sell a different radio, (IC-718) and keep the
TS-570 and thus the headset. The plan then was to use the MH2 for the
K2. I will still be using the MH2 primarily for the K2. But I want
to be able to use the headset on occasion as needed.
I understand the instructions for wiring up the MH2 on the K2. How
will this impact the use of the headset?
This email suggests it only needs straight across jumpers.

If that is the case, and I do have the Kenwood adapter already, then
if I just put the straight jumpers in, I should be fine.
If I want to use the MH2, then I need to either put the resistor in
the microphone somehow (not something I am looking to tackle with my
large hands) or make an adapter cable for the MH2 that has the
resistor in it.
Am I barking up the correct tree hear, or chasing a feral goose?
