Re: RE: [Elecraft] Two K2... One Mic... Zéro Problem ? :-)

OK Don, thanks for ideas...

I'm looking the ability to receive from both K2 at the same time. But when one K2 is TX, the receiving K2 will be off automaticaly (antenna momentary disconnected). When TX finished, both should receive again. The only manual operation I see is when I want to choose from wich one I would like to TX with. The antenna switching technic, with relay I guess, must be automatic.

This module could be like a RF "power sense" autoswitching device... And I think that a very short time delay (a few ms at least) must exist between TX and RX to make sure that the antenna on the RX K2 is really off.
