I need help with the K1. With a antenna, or dummy load I get these results. I am using a 13.5 v. power supply.. 10amps I get 1.9 watts and 1.0 SWR. When I first put 8 fresh batteries internally in the K1 I did get 5.3 watts but now the AAs are down in voltage Paul Gates Elecraft K1 #231 XG1 kd3jf at hotmail.com
