working fine on Windows 10 but hanging when running on windows 7. Turn it off kapersky antivirus protection then solve the problem. Regards On Wed, Sep 25, 2019, 14:54 peter_pc2a <pc2a@...> wrote:

thanks for trying at least :-) If you're running the latest release (if not, you should be ;-), please do try to use the command line option "-D logfile.txt" This will log all debugging information to the file name you specify. You can then try sending the log file to me after a crash/lockup, and I will try to see if I can figure out what's going wrong. If you're the curious type, and want to follow along with the debugging, "-d" outputs log information to the console. My email is mihtjel@... if you want to send me a log file. I hope you get it working! -- Rune / 5Q5R On Wed, 25 Sep 2019 at 08:54, peter_pc2a <pc2a@...> wrote:

No Virus protection is on, so must be something different

I'm not certain quite how it works via groups.io, but I did attempt to put my email (mihtjel@...) in the body of the email I sent earlier, in order that Peter (and others) could contact me directly, should they need to. I should probably set up an official email address for nanovna-saver at some point, given the number of users it's starting to accrue, but for now, gmail is doing fine at sorting them for me. ;-) -- Rune On Wed, 25 Sep 2019 at 15:50, BruceN <k4tql@...> wrote:

Using Thunderbird, and perhaps other email clients, you should see the poster's full email address on the "From" line at the top of the email header. For instance, when I look at your email (to which I am replying here), I see k4tql@....

One can right-click on the email address and copy it. DaveD On 9/25/2019 9:50 AM, BruceN wrote:

I am running nanovna-saver.v0.0.11 on Win 7 - 64 bit and it is working great. The software is very useful and seems to be quite stable. Rune: I know you are quite busy. Here is a suggestion: I would like to see group delay added to the measurements. Thanks, again, for all of your great work. -- Bryan, WA5VAH |

Thanks for the suggestion, Bryan. It sounds interesting. Do you know if/how
group delay is determined from S-parameters? I'm not really an RF engineer, so I have had to figure out all these things from the ground up ;-) (Also, no more busy than I can easily answer emails. :-) -- Rune / 5Q5R On Wed, 25 Sep 2019 at 16:17, bryburns via Groups.Io <bryburns= [email protected]> wrote: peter_pc2a |

Hi Rune,
The group delay (GD) is obtained from the transmission phase, S21. The negated value of phase shift calculated as the small change in phase shift occurring with a small change in frequency. The difference in phase with difference in frequency (the aperture) taken small enough to arrive at an accurate value for GD. The site below is a good reference and provides a useful calculator so you can test your routine: Regards, Alan |

Thanks Alan! See, I didn't even figure out it was an S21 measurement :D

We had the same problem here... works with Win10 but not Win7. Not sure if this is the cause of your problem. We found that Win7 did not have latest Framework 4.0.

One other note Rune. And others can comment in if I am off base. After thinking about this a bit more, there may be an issue in obtaining GD and what is known as differential group delay accurately particularly for NARROW band networks. The Nanovna is currently limited to 101 data points. No issue for wide band networks but for narrow band there may be a problem with just 101 points to obtain a sufficiently small aperture. As a rule of thumb, to get GD proper, the frequency step size must be a fraction of the network band width. Taking that into consideration, 101 data points may fall short of the desired resolution to obtain GD. Maybe not, have to run a simulation for grins on say a crystal filter or a very high Q LC filter and see if this is an issue. FUN!

Hi George (and others),

the .exe for NanoVNA-Saver is built on Windows 7 - on a virtual machine that's used for nothing else. It has the build tools installed, but otherwise is just a (fully updated) clean Windows 7 install. I'm not sure what else I can do to make it run on a clean Windows 7? I *do* assume that people install updates - I don't think I have any way to generate executables that will work on un-updated machines, or indeed on Windows XP, which I've recently discovered there are still people using. If you have any suggestions on what to do to make it more portable, let me know :-) -- Rune / 5Q5R On Wed, 25 Sep 2019 at 21:59, George <steber@...> wrote:

one of the features of NanoVNA-Saver - the prime one, really, from my point of view - is the ability to sweep many more than 101 points. I think I've used it up to 20200 points at one time, but I believe there are people who have tried more ;-) So it should be possible to get decent data, I hope. -- Rune / 5Q5R On Wed, 25 Sep 2019 at 22:02, alan victor <avictor73@...> wrote:

You are doing fine work. Keep it up. But I hope you can understand the frustration of not being able to run the software on the many laptops and other computers that have not been upgraded to Win10. We do not want to install a bloated Framework 4.0 when it already has Framework 3.5 --- just to run one program. If you ever get it to run on WinXP that would be a big big plus! I'm sure a software developers life is full of headaches. Hope you hang in there. Your work is appreciated by many here. By the way, how did this thread get hi-jacked away from dealing with Win7 issues? On Wed, Sep 25, 2019 at 01:12 PM, Rune Broberg wrote:

I'm not suggesting you need to upgrade to Windows 10 - as mentioned, the app is built on and runs on Windows 7. I don't know anything about Framework 4.0 or Framework 3.5, but a quick look reveals that Microsoft .NET Framework 4.0 was released just under nine and half years ago. I don't specify anything in my software to say that it's required, but I could see why the build software might assume it is installed on PCs in current use. ;-) I do think it requires some version of the Microsoft VC++ redistributable packages. But again, I couldn't say which: The build machine never had any externally added to it that did not come automatically with Windows Update. As to thread hi-jacking, I have no idea. I try to reply to the posts that address me and/or my software fairly quickly, and I rarely pay that much attention to the rest of the thread unless I really need to. I can't keep track of all the threads I get involved with anyway ;-) -- Rune / 5Q5R On Wed, 25 Sep 2019 at 23:04, George <steber@...> wrote:
