I understand that there is a 4.3 inch version available. Has anyone purchased one? If so, I am in the US. Where is a reliable source to purchase one?

I got one like this https://www.ebay.com/itm/202403566060/ -- it has the advantage of skinny profile, display on big screen; the disadvantage of latency, you better move pretty slow to solder smt

Well, it's actually an itty-bitty 2-port VNA that, within its specs, provides both reflected and through measurements of RF circuits. So, for they typical ham, mostly antennas, and maybe filters.

#54 : [TheLeastVNA] Code with an Application to [NanoVNA] Hello, Allow us, please, to inform you that, as we promised it, we just uploaded the /F/L/O/S/S [TheLeastVNA] at:

Hi Bryan, thanks - I figured it was something like that, but it's nice to have it confirmed :-) With your description of how you did your calibration, I'm sure more people will be using these fields -

Rune, I just figured out what is causing the crash I referenced above. If a user leaves one of the text boxes in the "Calibration settings" area blank, no number at all, nanoVNA-Saver will immediately

Jeff got me going, the driver was not installed. Now to get rid of the Smith chart overlay. BTW, the R and j do come up fine on the Saver, Thanks Rune. Mel, K6KBE -- Mel, K6KBE

Hello Mel, I assume your NanoVNA is plugged in, turned on(!), and that you have tried pressing the rescan button? Assuming you are running Windows, you may need a driver installed for your system to

Hi Erik - Can TAPR VNA save those nanoVNA absolute values to files?

Rune, Good Day, First time user or want to be, hi. 0.1.3 is downloaded and comes up fine, but does not present a COM port number? What is the best way to approach this? Thanks, Mel, K6KBE

KV5R, that's great to hear! :D I try what I can to make it scaleable, but I don't personally have a high-DPI monitor (nor serious vision issues - yet), so I don't have many opportunities to test it. I

Hi Rich, it should work with most versions, but I have good experiences with edy555's 0.2.3 firmware: https://github.com/ttrftech/NanoVNA/releases/latest There are instabilities and bugs in firmwares

Hi Rune, I am very happy that your software re-scales everything, even if it does cause a little "jitter" of the graphs' sizes... I use so many software tools that do not re-scale, and everything

Rune, What version of the firmware should I install to use with NanoVNA saver? Rich, WD3C

OK, great. One less thing to test. What are your thoughts on the transient response of the 3v regulator data sheet I've attached. Also, I wonder if you could lower the noise by running from 2 Li cells

Well, has anyone measured the +5 V rail(s) to see how noisy they are? Once that is done the specs for the parts powered by +5 V would need to be looked at to see how noise is too much. DaveD Sent from

Erik, This data seems to suggest that if we had better by-pass capacitors on the 5V supply noise in measurements would be reduced. Would you agree? -- Bryan, WA5VAH

Hi sala nimi, any examples please? Thanks. Have a fun! N.V.
