Re: NanoVNASaver 0.4.0 crashes on start

Stan ... YAY!!!!!!  I know that was probably an easy answer for you, but seriously THANKS A LOT !!!!  I have a few antenna analyzers, but the NanoVNA is my only VNA and I need to make measurements of choking impedance this week.  Thanks for helping me keep ON schedule!  de K7ZOO

Re: NanoVNA-Saver 0.1.3 MAC

Solved....
I may have had multiple issues, but this is what I did.
there were two versions of python on my machine, so I uninstalled both and reinstalled.
I have a Macbook Pro with a M1 chip.  I had to install PyQt5 using a Rosetta terminal:

I was then able to install NanoVNA Saver and it ran.

OK, thanks!

Re: NanoVNA-Saver 0.1.3 MAC

I guess I missed that message, but it appears from your build logs that that requirement does not exist in your build, since early in the log (sorry, don't have that message . . . ) it clearly shows that it is looking for a version above a certain  level, and not 5.11.2 specifically . . .

Re: NanoVNA-Saver 0.1.3 MAC

It looked like it was having a problem building related to sip, so was hoping that wou,d help.

I'm not honestly clear what you are calling a "PyQt restriction" . . . Building PyQt is often a part of the install (if not already present) and absence of subcomponents can affect it as well.

Re: NanoVNA and VNAsaver

#28169

Yes, that should work. Note that to get uncalibrated data from the nano,
you need to reset the calibration,  since it always powers on with whatever
state is in save slot 0.  That is why many find it easier to save a wide
calibration in slot 0, e.g. 50kHz to 900M or whatever your nominal total
range, and just use that with Saver.  I think that is the idea behind the
Saver author's statement of calibrating the nano first.

where can I get that replacement plsThere *is* only one board, so you're probably looking at just buying a nanoVNA, and having a spare battery and LCD display.? You might ask whoever you bought yours from if they'll sell you just the board, without the "case" or LCD.

You probably cooked the bridge (CH0) or the 20dB pad (CH1), and maybe some downstream components (the mixers).

They're readily available, but they *are* SMT devices and a bit tedious to replace.

It would be interesting to know what actually cooked.? For instance did the SA612 mixer perform as a sacrificial fuse, or did the analog inputs on the audio chip also get fried.

If you're interested, you can probably try to diagnose it if you have an ohmmeter, and an oscilloscope.? For instance, assuming you can "talk" to it, you can set a frequency and see if the synthesizer is putting out the two signals 5 kHz apart.? You can look and see if the output of the mixer changes when you change the termination on CH0.
