Or... you can use the standard stereo mini plug which is usually
supplied with condenser mikes and plug into the mic jack on the rear of
the K3. I use a Yamaha CM550 and it plugged directly into my K3 - just
had to remember to enable bias on the rear mike jack. I don't know
which flavor of mic those two are, but page 28 of the K3 manual (and
nowhere else I can find) explains what to do.

Bob,
The Elecraft mic pinout is ALMOST the same as Kenwood's
The Elecraft pin 6 carries +5 volts while for Kenwood, the +5 volts is
on pin 5.
Pin 5 for Elecraft is the Function button.
If your microphone does not require +5 volts and does not have buttons
other than PTT, then you only have to be concerned about pin 1 (AF),
pin 2 (PTT) and pins 7 and 8 (one for PTT return and the other for AF
return - both are connected together inside the K3).
Icom and Yaesu are not as straightforward, see the G4WPW info at
https://www.qsl.net/g4wpw/date.html for details on the pinout for
those mics.
If you can do a bit of soldering, you can make and adapter for the
price of a male and female Foster connector and a bit of wire. If you
rewire the Foster connector on the mic, you don't need any adapter or
connectors at all, just a bit of solder, to unsolder the wires from
the existing connector and solder them in the correct pins for the K3.
OTOH, if you wish to switch back and forth between the Icom/Yaesu
pinout and the Elecraft, the adapter or the MFJ box would be the best
choice.

It appears that MFJ makes a box, designed to convert one brand’s mic
connector to others. It appears to be programmable, using jumpers.
I believe the Foster connectors on the K3 or K3S are wired the same
as Kenwood’s.
The model number is MFJ 1263. I have not used or seen one, so cannot
comment on its utility.

I have no microphone for my K3. I am usually on CW or the digital modes.
Now I want to get on the KY Phone Net on 3838.
So I talked DXEngineering and they know of no adapter plug/cable.
So, I have an Icom SM-50 mic and a Yaesu MD-100 mic.
Anyone know of an adapter connector that would fit either to adapt
them to the K3?
Or maybe a universal box that lets me plug all the mic's in and have
a cable to the K3 ....
Also run an Icom IC-9700 FWIW.
