Two transceivers is a typical contesting setup. I do not believe that you
are contester so it would probably have little value to you. Typically a two
radio station on operator setup (SO2R) has one transceiver on one band and
the other on a different band with filters to protect the receivers. With
super human operating skills very high run rates are possible:

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.
