for those who like to change microphones frequently: 

I have made microphone configuration plugs with the necessary connections 
on the plug. So it is easy to open the cover, change the plug and you are set.
I have installed the EA3BLQ digital PCB, to feed the Pactor modem inside 
the K2, but you can also make a computer band cable to the inside of the K2 
and mount the plug there. You can see my K2 top cover here:

The plug can be seen in front of the band cable, PIN 1 marked with a red 
wire loop.
