[Elecraft] How to Isolate 2nd Transceiver in two Radio Base Station (WU6R / Mark)

[Mark Wheeler]

I see lots shack photos with two transceiver setups, especially two Elecraft K3S radios; how do you isolate the 2nd transceiver or SDR receiver (SDR Play, for example) so that you do not damage one transceiver while transmitting with the other?  I am assuming there is a way to use both radios at the same time.

Can I safely use an antenna switch to switch between multiple transceivers using one antenna, or will I risk damaging the non-transmitting radio on the other side of the antenna switch?

If there is a way to do this can anyone explain their setup?

Thanks.
