[Elecraft] K3 KEY OUT, hi or low on TX?

[Don Wilhelm]

Jamie,

It will short the active wire to ground.

The KeyOut does not source any voltage, it is like a switch, it is 
either open or closed.  Any voltage is sourced by the amplifier or other 
external device.  It will only work with a positive voltage.

The voltage and current listed in the specifications are the greatest 
that the FET can handle.
