[Elecraft] Aviation noise reduction headset for K3?

[ron hess]

Am setting up a newly acquired used K3 which came with no microphone.  Is
it possible to use an adapter to make a Lightspeed Zulu noise cancelling
headset work for the K3.  I got very nice reception using the cell phone
attachment line but can't identify any microphone function.  The two main
lines are different sizes, per standard aviation usage.
