Nick All Messages By This Member #29011 Using nvna-s 0.3.9. Why does nvna-s default to a sweep range of 1M to 100M when I connect to the device? I have set the cal range to 100k to 50.1M on the device itself. Where is the nvna-s default sweep range stored?

I have set the cal range to 100k to 50.1M on the device itself. Where is the nvna-s default sweep range stored? The NanoVNA doesn't have very good visibility into its internal state, i.e. the sweep range and other parameters. The software can send a sweep command to get the current sweep setup sweep – sets the start/stop for the next automatic sweep, but you never know when that will happen or when that will be finished and issuing a pause command stops the automatic sweep (per QRP) - Usage: sweep {start(Hz)} [stop] [points] - If no inputs, then prints current setup eg: 300000000 500000000 101 but there's other things that are more difficult. So the tools tend to have their own sets of defaults (stored in an .ini or setup file or equivalent). NanoVNA-Saver also can do the nice thing of commanding the NanoVNA to make multiple sweeps over a subset of the range, so you can get 1000 points in a sweep, for instance.

C:\Users\Your user name here\AppData\Roaming\NanoVNASaver\NanoVNASaver.ini Thanks Roger. Using Linux Mint here. Found the file though ~/.config/NanoVNASaver/NanoVNASaver.ini But there don't appear to be any sweep settings in that file except SweepColor=@Variant(\0\0\0\x43\x1\xff\xff\xef\xef))))\0\0) Please could you look at your NanoVNASaver.ini file to see if it's different on Windows.
Nick All Messages By This Member #29065 Upgrading to version 0.4.0 fixed this. On connect nvna-s now sets scan range to that set in the device.
Glen Jenkins WB4KTF All Messages By This Member #29072 Hello Folks, I am trying to install Nano-Saver for the first time. I downloaded Version 0.4 and unzipped it to my PC. When I run the .exe file a DOS type window opens and then NOTHING else happens. Please advise what I am doing incorrectly. ----- Glen Jenkins, WB4KTF, Austin, TX
Stephen W9SK All Messages By This Member #29073 My guess is that you may not be opening it with administrator privileges. Check your PC user account to see if it is a Standard or Adminstrator, and change as necessary. If it is already Administrator, right-click the nanavna-save exe file and select 'Run as Administrator' to see if that cures your problem. Finally, make sure that app is white-listed in any anti-malware software you have installed (which may include Windows Defender).

Stan Dye All Messages By This Member #29075 Also, just wait a very long time. It takes saver two or three minutes (seems like forever) to load up all the required python stuff, after that command window opens, especially the first time you start. toggle quoted message Show quoted text On Wed, Jul 27, 2022, 2:23 PM Stephen W9SK <stephen@...> wrote: My guess is that you may not be opening it with administrator privileges.

Stephen W9SK All Messages By This Member #29087 Sounds like you have a lot of overhead background running, or slow/low resources, or both. Mine launches within a few seconds of the DOS terminal.

Stan Dye All Messages By This Member #29088 I think the startup delay has a lot to do with what version of windows you are using. Mine used to start up fast like that, 3sec or so - but after the latest Saver update, which happened to coincide with a win10 update, mine takes forever to start up, but then operates fine. I didn't make other startup config changes, so it's not likely that in my case. I haven't yet tried to investigate the delay, since I can just leave it up after starting it.

F1AMM #29089 Since I switched to nanovna-saver 0.3.10 -win7 the display time of the "console" window remains displayed for 12 seconds. Previously with version 0.3.8 it was only 3 seconds. It really is a great product. I don't know anything about Python; I have never done development in Python. From what I understand, Python is an interpreted language well not really that interpreted. Python. I have a multitude of them on my disk: 12723 files 941 directories 537 MB I think that's a lot. For example I see 28 python38.dll files in directories like _MEI00000 -- F1AMM (Fran?ois) toggle quoted message Show quoted text -----Message d'origine----- De la part de Charlie N2MHS 28 juillet 2022 04:31

For example I see 28 python38.dll files in directories like _MEI00000 This can be a problem... Some installers are less than smart, and copy all the files into a new directory each time, add that directory to the path that python searches, and then that longer path gets searched every time something runs. You really should have just one python38.dll for instance. It is possible to set things up so you have distinct python environments for different applications/uses (for instance, I have an environment for Python 2.7, and for Python 3.8, for testing purposes). But I'm assuming that for NanoVNA-Saver that's not what you're looking for. I'd go take a look at the PATH environment variable and see if the same directory appears multiple times.
