Re: errors of "error" models
@Gary O'Neil , N3GO - 17 December 2019 /g/nanovna-users/message/8294 Dear Gary, Your decision is really great. So, would you allow us, please, to ask you if could you reconsider your

Re: Are any of the NanoVNA sold on Amazon any better or worse than any others? Is there a better U.S. site to order from?
I'm pretty sure S11 directivity is a well defined parameter. It is the (uncalibrated) ratio between the |S11| reading when measuring an ideal load and the lowest |S11| reading when measuring loads

If you could produce a set of specifications, in a *format* used by Keysight, then people with the right equipment could compare the performance of one NanoVNA-H against and the specifications, and

Re: Cases
OK, I see there is a problem that can be solved quite easily. I have 3D printers and Laser cutters, so if you can give me till the New Year, I will work with you all to design and prototype a case

Re: Some test results using a NanoVNA
What's needed to connect my NanoVNA- to my Android phone to use the NanoVNA- Webb app? Just a usbc to usbc cable? Martin K0BXB [email protected]> wrote:

So how do you measure inductance using it? Could you tune a trap with it? How? Thanks. Martin K0BXB [email protected]> wrote:

Re: Cases
Searching ebay.co.uk has the same issue, no cases just nanovna units themselves. I made my own metal box, so not an issue for me. Maybe the vendors have placed a .com or regional listing condition on

Re: Simple example of interfacing Octave with nanoVNA #octave
Hi to all , I've solved the problem . The instrument-control pakage was installed. The mistake is that I was using the COM14 , that need a different sintax like hCom = nanoOpen("\\\\.\\COM14") instead

Re: Some test results using a NanoVNA
Hi Bob, It's interesting, and the translator translated it, I just had to put "space" in the right places. Still very understandable, thanks for the summary. 73, Gyula HA3HZ

To clarify how to load the instrumentation library use the Octave command: "pkg load instrument-control" from the Octave command-line prompt. But don't use the quote marks. -- Bryan, WA5VAH
