Addendum: After posting the last message, I reviewed the video link which I had posted regarding saving of stimulus frequency range. Then I saw that on recall, I have to press on the number displayed

I am using a 32GB micro SD card in my NanoVNA-H v3.6. I use it mainly to save calibration (https://youtu.be/DgvjlHsU0h4). I did not do any formatting, just inserted a new card and started saving

I recently bought an H4 v4.3. Was looking forward to being able to save plots from the nanoVNA to a micro SD card. But every attempt resulted in "fail write" message. I read that it cannot handle

Oops, sorry, already answered multiple times. Must remember that when we Brits are tucked up in our beds, you Yanks are still enjoying your evening's hobbies :-)

It's your calibration! O - Open; S - Short; L - Load (The 50 Ohm)

As a P.S. to my last comment (below), from a search i found a reference to yet another version of nanoVNA Saver (0.7.3). On one PC, the SV4401A would not connect (or would crash) just as in the other

Just out of curiosity...for the H4 the VF is entered as a decimal as 0.82. Is the F V2 VF entered the same or is it in percent? 73, Geoff -->AB6BT

No, you may have gotten a clone. Try NanoVNA.com Good Luck. ________________________________ Sent: Wednesday, March 5, 2025 8:17 PM To: [email protected] <[email protected]>; Orrin Winton

Yes, if you mean the value. Both 82% for RG-8X. Even if the VF was off maybe 5 meters still shouldn't come up with over a 1000 m for the 16 m / 52' length. ________________________________ Sent:

So i bought one of these on Amazon (SV4401A). They're $150 less on Ali Express, but i don't entirely trust Ali Express -- i've been burned twice by them. The last "burn" was $24 worth of fake coax.

Did you enter the Velocity Factor (VF) of the coax the same in both units ?

Clifton, the 1.2.40 firmware version is very recent, so you don't need to update. The correction item should be there in the calibration menu, but you don't need to worry about it unless for some

What does OSL stand for and where or how to find it on the VNA H4 or F V2 ________________________________ Sent: Wednesday, March 5, 2025 2:49 PM To: [email protected]

Once you complete your chosen cal., go back and check that the OSL actually shows as an OSL should. If so, that will assure your cal has taken hold. Dave -
