Hi all,

I bought a nanoVNA on ebay like on the attached photo. And as you can see on the photo, there are 4 traces on it. I only have two. And I have no idea I have to make the other 2 visible. In the menu I also have only trace 0 and trace 1

Anyone have any idea?

Best regards
Colin

Yes, you have the 2- track firmware and you are going to have to update the firmware to the 4 track firmware. See your manual or get a copy of the pdf manual. A link to the manual is here on this users group. I was aware this might happen from the seller I was dealing with, so I was kind to him and asked please... Update the firmware or double check that it is 4 track firmware and he did. It's no big deal to do but just another hurtle to jump and I have enough of those to jump already. Good luck. Alan

Thanks, I try that.

Hi Colin -
Your nanoVNA has a front cover that appears to be riveted on;
- does it have shielding ?
(should be visible between back cover and circuit board, near connectors)
- how to remove protective film over display?

Hi Oristo,

Yes I know that it has the protective still film over display. Because I’m not sure yet if I send it back to the seller. Because it doesn't match what I bought. The photo above is from the seller.

And no it have shielding :-(
