Ron, I didn't think to look at that last night, but I am testing it now into a dummy load at 50W. I am using an MFJ-4125 with about 18" of #10 "zip cord." This goes to a PowerPole DC distribution panel and there is another run of about 30" of #10 to the K3. On receive, I have 13.4 - 13.5VDC (1.15 - 1.16A). On transmit, it drops to 12.4 - 12.5VDC (~14.5A). The wires are not even remotely warm.
I do not have time to test with my Astron RS-35A at the moment, but I will when I get home this afternoon. I also have an Astron RS-20A I can experiment with.
