Indeed, it is optimized for 50 ohms, but I don’t know that I’d say the precision loses much of its meaning as you get away from that. Can you quantify your assertion? Ultimately, the accuracy

I'm starting to think that adding the washers, (in other words increasing the space between the NanoVNA's front/top cover and the touchscreen just a teeny bit) solved the start-up problem as well,

Hi We have the impression that the NanoVNA is as an impedance meter, a Q-meter or a frequency analyzer, while it is only a transmission line network analyzer, that is to say we have to do with

My version appears a bit different. 73 Jon, VU2JO [email protected]> wrote:

I have done a few surface mount repairs, and I have a tiny Oryx 6-watt iron and some tweezers :) But I can't locate the videos you refer to. I've tried searching on Youtube for every combination of

Fixed the jumpy menu (kinda). Put two 0.7mm/0.027in flat washers as thin spacers on rt. side on NanoVNA (see foto) to keep cover from pressing on touch screen.

Nizar, No I don’t believe Port Z function is in the latest version but check for yourself. https://github.com/DiSlord/NanoVNA-App

Hi Roger Need Please what is the latest version reference of Dislord modded NANoVNA-App windows program ? If It does have the Z-renormalized function ? Or Z0-renormalized function ?? H4 firmware

Normally this destroys some surface mount components. Unless you have experience replacing surface mount components a new unit is the best option. Also. There are several YouTube videos about this

I would assume significant and maybe subtle damage and replace it. Chuck K4TZO <charlesmorris800@...> wrote: -- Chuck Cole ?K4TZO

Today I was doing two things at once, and unfortunately transmitted 400W of SSB into my inverted-V while my nanoVNA H4 was still hooked up to my OCFD antenna! Although they are perpendicular, they're

VNA-QT is not a program for your NanoVNA. NanoVNA-QT (VNA View) is the native software for the NanoVNA V2 Plus4 and VNA6000 series. There are some very old apps for the NanoVNA like NanoVNA Sharp

Patience, my boy, patience. You can widen the RBW and VBW for faster scans. But you will lose noise floor. You can also decrease the number of segments you wish to scan to increase speed, but you

What are the alternative to vnasaver? I got it running fine but discovered that it is painfully slow and it doesn't mark frequency line in small increments. What I want is something that is fast as

Here's an update on the SVHFS 2025 Conference; Deadline for papers has been extended to March 17 Conference & hotel registration is open; details are in the attached file. Thanks, Robin Midgett

Ensure the STM driver is installed for the device. Refer to the wiki on the group website for more information about the driver

It wasn't clear to me whether the 10 pF test load that simulates the capacitance of the circuitry the filter feeds should be reversed along with the filter when doing the reverse measurement. Don had

I have found this one useful for initial use of NanoVNA as a beginner (*Absolute Beginner Guide to NanoVNA by 9A2JK*)
