[Elecraft] 2 radios, 1 antenna... finally a prototype!

[Dan Barker]

I'm not a so2r kinda guy, but I've read that stereo will help. Seems
reasonable - If the left ear hears CQ, answer with the left radio.

Anyhow, you may want to do some AF-OUT magic in the same box. You'd probably
want a switch for selecting what it does. Maybe K2#1 in left, K2#2 in right
or Last-To-Transmit in both and the other in the corresponding single ear,
or something else alltogether.

Just to make sure I'm clear on my message... this interface is made
for listening on two radios at the same time from one antenna. But
when one radio transmit, the other in mute by putting it's antenna on
ground and vice-versa.
