[Elecraft] K3: Using a K3 to route antenna signals to external devices...

[Dave Cole (NK7Z)]

A few months ago someone asked how to move the antenna signal coming in 
on the main antenna connector of a K3 to an external SDR via some 
connector in the rear of the K3.

The answer indicated connecting the SDR antenna to some connector in the 
rear of the radio, and pressing some number of front panel keys to route 
the signals from the antenna to the SDR...

Can someone point me at that post, or tell me how this is accomplished? 
The RF Signal flow on the K3 has always eluded me.

Also, is the output from the K3 at zero or close to zero when 
transmitting? i.e. is it safe for the SDR?
