I flipped a coin about three weeks ago and ordered an S-A-A-2 (NanoVNA-V2) analyzer for our ham club. We already had one the other three variations (-H_v3.4, -H4 and -F) and have been very satisfied w

edy555 has released firmware version 0.7.1-20200321 for the NanoVNA. No major changes from version 0.7.0: Contributions from @DiSlord - shrink flash size - faster sweep - added color command Added lev

How do I remove the screen cover sheet. Do I have to disassemble top cover?

I'm wondering what folk are using for storing and transporting their NanoVNA and accessories. My little cardboard box is falling apart. Thanks -John

Has anyone used the nanovna to make tunes coaxial stubs? I was thinking you'd need to get rid of the jumper which would add length to the overall stub. I picked up an SMA to SO-239 connector which hop

Hello everyone, specially our developers. Since we have an Antenna Analyzer version of our FW, can we have it more simple for field use? Simple information like SWR, or at least lowest SWR, etc... Som

If you are updating your previously installed NanoVNA-Saver in Linux, the procedure is the same with one exception. If you try to do the gitclone, it will complain that the directory is not empty. So

Hello. I am new to the group, having just received my new nanovna yesterday. At first, it was working great with the nanovna saver program. Then, it only shows a light blue screen. No display at all.

Is there a preferred hardware vendor located in the USA? I'm looking at buying this offering. Anybody see a problem? Thanks https://www.amazon.com/gp/product/B07Y53RCKW

I'm hoping to have access to a more expensive VNA later this week for comparisons but for now, the nanoVNA-H looks very promising in terms of accuracy near the top of its frequency range: https://ae5x

erik, I've been trying to transfer some of my NanoVNA scripts over to the S-A-A-2, and although its communicating, I'm operating blind. Any remote commands to the S-A-A-2 cause the screen to go white

I am currently designing a receiver for the 40 meter band and will be using an NE602 for my mixer. I have most of the individual circuits built (pre-amp, bandpass filter, crystal filter etc) and they
