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

[Don Wilhelm]

Dave,

Look for a post by Bob McGraw.

In brief, it takes a TEE adapter and 2 short pieces of coax.  Put the 
adapter between the 2 pieces of coax, and then connect one coax to ANT 
OUT and the other to ANT IN.  The SDR is connected to the TEE adapter.

To get output to the SDR, you must set the K3 for the RX ANT.

If you are not interested in a multi-band input to the SDR, but only the 
K3 IF (for a panadapter application), then you can simply connect the 
SDR to the K3 IF OUT and set the SDR to tune 8.215MHz.

In both cases, the SDR will be protected during transmit.
