Martin, ACC Pin 10 is a low power (10 ma. max) copy of the KEYOUT connector on the rear panel. It is open circuit until the K3 is keyed (or PTT or VOX), and then it goes to a closed circuit condition. So yes, the K3 pulls this pin to ground during transmit, and it should work well for keying a

Folks, I asked Elecraft about this before I bought my rig in January; they said it's "on the list" but not as easy to do as one might think. I figured they could just drop an FTDI chipset into the rig in place of the RS232 jack, but it seems that it's not all that simple. Patience is a virtue.
