Currently I have a manual switch to switch headphones between radio 1, radio 2, and one ear for each. Seems to me a relay setup to switch both ears to the non-CQing radio, while the run radio is xmitting would be more efficient. Has anyone done this? I'm not lokking for something to switch mics, keyers, etc., just the receive audio.
