Hi VNA-savers,

Im in the process of trying to save my sanity and, if I appear to be a tad pissed, I beg your forgiveness.

Yesterday, I had zero problems, with NANOVNA-Saver. Worked perfectly. The program even found a port I had never seen before - hidden or otherwise - Com Port 8.

Just now, the sftwr wont even recognize the VNA, yet when I unplug the USB connector, Device Mgr notices the hardware change.

I have tried combinations & permutations of opening & closing the sftwr, disconnecting and reconnecting the USB cable, with zero luck and I aint joyed.

DM lists Ports 3, 4, 5, 6 & 7 but no Port 8, hidden and in plain sight, for all the world to see. The VNA screen goes to a beautiful, pastel blue, when connected via USB cable, without a connection.

I have the USB cable, from the VNA directly into the motherboard.

I have version 0.5.3 and was notified, today, there is an update. I can find no ver 0.5.4, which must remain another issue. The program also loves to close, with unknown keystrokes, to me. Please note: not crash, just close.

OK, there are a few possibilities here. Based on what you wrote, I think
the two most likely are:
1 - Your computer updated overnight (windows does this from time to time),
and something became incompatible. But ver. 0.5.3 is very recent, so that
shouldn't be an issue.
2 - Your nanovna had a failure. Please share with us which specific
NanoNVA you have. I am worried when you say it shows a pastel blue screen
when you plug it into the USB port - the nanovna's I am acquainted with
should not do that - the nano screen stays with a normal operational
display when plugged in.

My Windows 11 laptop installs updates every Tuesday so that could be a factor in your problem.

Try NanoVNA-App instead. IMHO it's a much better and more stable piece of software.
