Thanks. Loaded it and all I get is a solid white line down the right edge. My touchscreen is faulty for sure. Thanks again. Andy - W4KIL

I made a special firmware to check the touchscreen. The test loads immediately upon startup.

It sounds like there is something pressing on the surface of the touchscreen.? Remove the front frame and check for any debris, then try operating with the front frame removed and see if it

Herb, I did not see that "my through measurement was about 10 dB down." Nor were other things centered around 50 ohms on the Smith chart. But.... Thanks for the tip. I will try it again and report

Bryan, I had problems similar to yours when I upgraded to edy555's 0.2.3. After calibration my open and short loads on the Smith display stayed centered around 50 ohms and my through measurement was

OK. Tried it with Putty. The X coordinate for the lower right always comes back with a "0" . I think my touchscreen is faulty.

Your suggestion is very similar to the one I wrote about half an hour ago about the vector voltmeter option on a FieldFox. I attach a screenshot of that. The FieldFox one actually shows less than you

Greetings to All, I am very much enjoying the NanoVNA, and very grateful to the developers for making this amazing and affordable instrument! I would like to suggest a useful display format for use

Rune, I tried that firmware; however, I was getting very strange errors, even on the nanoVNA screen, with that version of firmware. When measuring an open I frequently get data which is obviously in

Right on! There are many questions that don't seem to be asked, and answers don't always much sense without some hands-on tests and data. I got started with this round watching comparisons of assorted

I share your opinion of this seller; they seem to be giving away their items. Too good to believe. Stuart K6YAZLos Angeles, USA

Rune, The logfile.txt is attached. I ran the initial scan, one without a calibration loaded, loaded a calibration, and then ran another scan before closing the file. You can probably tell all that

Hi Bryan, could you try running a multi-segment scan, but after starting the program with the command-line option "-D logfile.txt" - and sending me the resulting log file? I would like to see if it's

I recently downloaded the latest nanoVNA-Saver version 0.1.2 from https://github.com/mihtjel/nanovna-saver/releases/ . I am using firmware which gives the following information from a terminal window:

I bought a FieldFox at some point and paid for the “vector voltmeter” option. I was expecting a high impedance input, but it was not and I felt it was a bit of a waste of money. All this expensive

When did non-gekko white nanoVNA first appear?

PuTTY https://putty.org/

Yes, before the firmware upgrade.

Hmm, the calibration within the firmware should be the same as if it's activated from serial - it puts a couple of marks on the screen and asks you to press them? If you have a screen that's for some
