[Elecraft] K3 - Microphone Connector

[Don Wilhelm]

Roger,

Yes, the up and down operation is by grounding those pins - a momentary 
pushbutton.
As of yet, there is no function done by the "Function" pin.  Back in the 
initial K2 days there may have been some operation thought about, but 
never implemented.  Treat it as an NC - do nott connect to it until it 
is defined.
