Hi Chris,

The Key output works as it should do, there is no output from it at all as
such. What it does do is in the transmit mode it will "sink" up to 200 volts
at 5 amps, so in other words if you have a 24 volt relay with one side of
the relay is connected to +24V and the other side connected to the centre
pin on the Phono plug, then every time you operate the PTT the relay will
activate, this is for operating any external equipment like linears or any
other equipment that needs to be operated on the PTT line. I use this port
to activate my linear, in my case I use a FET transistor as I have various
lines that need activating or de-activating as the case maybe. 

Happy New Year Chris

73 Paul.
