Nels, I should have said Hi-Z broadband transmission lines. Of course the tube amp situation is as Dave stated. I went to https://hamwaves.com/zc.circular/en/index.html to calculate the spacing for

I ordered a Nanovna H4 from alibaba begenning of the month, she told me it would ship before the 15, but did not had any news since. Am I the only one?

It's not just the Jog Switch it's also the way it is polled by the software. Replacing the jog switch with push buttons improves the operation, mainly because at least you can feel the positive click

I am no longer in front of the device, but I am pretty sure there was CH0 preceding all 3 of the active trace readouts (RL, SWR and Smith). Is there anything else that could have prevented the SWR
