One can rewire the mic plug of an HM-36 to work with the K3 as 
far as the mic and PTT.  However, unless the cable has a spare 
wire it will not be possible to make the up/down buttons work. 
Icom uses a single connection for both up and down.  "Up" grounds 
the function lead directly while "Down" connects the function lead 
to ground through 100 Ohms.
