Think I found the problem. Yes, running on a dummy load.
Not the K3 Utility software, does the same with the update. Seems to be a power supply issue, why it bothers so on 50 MHz I am not sure, but I also got it to do it on the 75 meter band once, think the overload protection in the supply is just triggering. I'm charging up a battery now for the real test, will know tomorrow. Rig worked just fine, ran the New England AM QRP this afternoon on 3.880 MHz - 3:00PM EST, just fine. Thanks for the help and suggestions. Cordially, Bruce J.
