If you can't install nanovna saver, I recommend nanovnaPartner, which works under XP. You can find the latest version of nanoVNA Partner v0.19 on my website (ha3hz.hu) 73, Gyula HA3HZ

It is likely that the nanovna-saver will work from python under XP. However, Python 3.5 and above will not work on Windows XP. Try 3.4.4 and if you succeed in installing Qt5 then you are close to

Re: Calibration help - above my pay grade.....
Not only can our ears not detect much below 30 Hz, our radios don't do too well with that frequency and below, either. Most cut off 'around' 100 Hz. For those who must split hairs on frequency

Thank you, Herb, With your advice, I will try the nanovna-saver on Windows but thought I'd try the Web app just for kicks. I wasn't aware of the Web app until I saw your mention of it in this post.
