And of course, the software should remember where it was when it was stopped, so that it would start from there next time.

Re: Unwrapping Phase
Maybe because nobody bothered to try? <grin> Sometimes, I find the derivative of unwrapped phase (group delay) more useful, too.

Re: Nano VNA SAVER graphs of a 40m loop antenna
I have a 40m 144' horizontal loop also at about 20'. It is a right triangle. The pointy end is due east and is a little lower. I feed it with BalunDesigns 1:1 balun and then about 55 feet of 450-ohm

Re: VNA buying aid
I don't see much mention of the SAA-2N v2.2 Does everyone recommend the H4 over the SAA-2N? The price difference is not of concern I am more concerned about functionality and support. Brian W1BKW

Re: VNA buying aid
Nanovna-H4 is a great basic vna, if you don't need multiple GHz frequencies. It runs the latest firmware and is actively supported. And you should be able to get one for less than $100

Re: Nano VNA SAVER graphs of a 40m loop antenna
Hi Jim. Thanks for the reply. The answer is simple. Convenient! A pair of trees are there, about 100 feet apart and between them, nothing. No balun used. The ends of the dipole are away from each tree

Re: Nano VNA SAVER graphs of a 40m loop antenna
Hello Alan Did you start with some ideal calculated length for 7.05 MHz, set the dipole at 7 feet high and then trim the length for best return loss? Or perhaps put up precut wire for a higher

Re: Is a negative Offset Delay in ps ok?
Hi Stan and others, Thanks for the reply. Based upon my photos from earlier in the thread does a negative offset delay seem reasonable. It doesn't to me, but my experience is limited. Best, Chris

Re: Is a negative Offset Delay in ps ok?
Normally you try to calibrate at the reference plane where you want to take the measurements, and the delay is set to 0. The e-delay is a method of adjusting the position of the reference plane before
