[Elecraft] Diversity receive with ant1 and ant2?

[tomb18]

Ok, I have more answers.
If the sub is sharing an antenna, you do not have to worry about antenna
isolation, only if you are using a separate antenna for the sub. 
Furthermore, the RF on the receive antenna should not be higher than 2 Watts
of power.
Now this opens a question; Why didn't the K3 design allow an option to
automatically isolate the sub on transmit i.e. either disconnecting the
antenna completely or grounding it?
This would have given the sub much greater utility. Of course this can be
done with a relay and the key out but this would fix the antenna to just one
since it does not seem that there is an easy way to tell which antenna is
the transmit antenna externally or is there?

I would like to be able to use diversity mode with ant1 and ant2 but choose
which antenna will be the transmit one as I am listening (reverse ant1 and
ant2 role depending on the signal).
Is there a way to sense the rf signal in one antenna and then trip a relay
to short the other antenna to ground?
