Hi Jean-François I use two K2's in an SO2R (single operator, two radio) configuration for contesting. I listen to one in one ear and one in the other. They are controlled via KIO2's with a computer. The software allows me to transmit on either one, but prevents me from transmitting on both at the same time. The SW also allows me to listen to both (one in each ear) at a time, or, either one by itself in both ears. I have very little interaction, if any, between the radios, at QRP levels. The SW I use is NA10. The NA10 manual has a diagram of the control box to control both radios with a computer. Very simple and inexpensive to build.
