I got my Nanovna-H a week ago and after many tries I can't get it to display SWR trace. I now have it so messed up I need to restore it to factory default. So I seem to be dumb and need help. Can anyone tell me how to set it up for doing SWR readings and I might need step by step guidance. Next, how do I restore to factory new settings. Thanks for any help to get me on track, Carl
