[Elecraft] K3 with SDR-IQ and external antenna for SDR-IQ?

[K7MDL]

Can use the K3's RX Ant input.  

For other purposes I brought out the internal ATU's connection to the SubRX
using the ExtRef BNC hole.  I jumper it to the AuxRF Jack for normal
operation.  Pull the jumper and you can route the RX side of the alternate
antenna (now presented at the ExtRef jack) to a transverter and optionally
feed it back in to the SubRX or to the RXAnt input.   So it is like RxAnt
function for the alternate antenna and SubRx.  No chance of TX damage.
