Kenwood/Elecraft and Icom put the mike element on the same two 
pins 1 and 7.  Unfortunately, Kenwood/Elecraft use pins 2 and 8 
for PTT where Icom used 5 and 6.  

To use the SM20 with the K3 you have two choices: 

1) rewire the SM20 plug to move PTT to pin 5 and PTT ground 
   (chassis) to pin 8. 

2) make an adapter cable -
