[Elecraft] What's New at Dayton? dual rcv

I think you would like to have the features of something like the Orion, but
for the price of two K2's. You would like to operate each rig as stand alone
on two different antennas.
You would like to integrate the operation of both rigs and mute the second
rig while the first is transmitting while on the same band.
You would like to select the audio so that you can have "either or" or both
rigs in stereo.

For instance, it seems you could pick up the receive signal from W6(XVTR
Bypass) to an outboard phono connector so that you could split the receive
signal between the 2 rigs.
More thought has to be put into this. It's going to take input from more
folks and I need to get a K2 at Dayton so I can play with this. I'm sure it
can be done.

Tony;

Thanks for picking up the discussion. I had a few direct responses, but
got busy with a project and had to drop this for the time being. Now
that I have at least a few minutes of free time, let me ask a bit more.
I see why you would want to do it, it makes a lot of sense. It is the
how that still puzzles me.

OK, so let's set up hypothetical station with a pair of K2s, the audio
output of one connected to the left headphone channel and the other to
the right. Each can operate pretty much independently at this point;
you can set the bands individually, key both independently, and so
forth. You can hear both received signals simultaneously. You then add
some sort of box that determines when one is transmitting and
"disconnects" the antenna input of the other one (ground it, etc) so
that it doesn't get overloaded. Either k2 can connect to any antenna,
but suppose we have a setup that allows them both to be on the same
antenna at the same time. The TX protection keeps the receive unit from
being blown up.

So what else is missing from your scenario? Is there some sort of other
synchronization needed or something to allow controlling things on both
radios together? What am I missing?
