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*)

it works, thanks

All three plots below are for renormalization from 50 to 330 ohms. Red used the forward and reverse measurements while blue is forward only and green is reverse only. The "only" measurements set S12 =

You should try NanoVNA Saver or NanoVNA app.

is there a beginners guide to connecting your nanovna-h to a pc? It may not be as simple as I am thinking. I have a nanovna-h edy555 ver 0.4.5-1 efbbceca when I connect it to my pc it shows up as

Hi Brian, Thanks big time for sending me the .s2p renormalized file. As a reminder to everyone your renormalized curve used my original forward and backward measurements of my ceramic filter using a

Hi Brian, Can you post or email me the .s2p file for your renormalized curve (red curve). I want to overlay my curves I obtain with resistive matching. Thanks, Don (wd8dsb)

VNA is the wrong tool (coherent detection depending on harmonic structure, and with a single detection bandwidth). Use a nano Spectrum Analyzer

All of this begs a simple question. Use the NanoVNA as a Field Strength Meter. Why - Just built a new antenna using the NanoVNA to adjust it to the operational Frequency and adjusted the impedance for

I forgot to mention that initially NanoVNA-App would not load the renormalized .s2p file. I had to manually change R 330 to R 50 in the # line to get it to load. Before I discovered this, I used

The plot compares S21 of the forward 50 ohm file with S21 after forward and reverse were renormalized to 330 ohms. Stopband details of the renormalized curve differ from your earlier curve using a

Hi Brian, Your wish is my command. See attached .s2p files for my ceramic filter with 10 pf load connected direct to NanoVNA-F ports tested forward and reverse connected. Note: I set my NanoVNA
