Best SW for SDRs but some defects.

[mistergitj]

I am running V7.4.0 under W10 with a AirSpy for the last couple of months. I have several years of experience with other SW and other SDRs. SDRangel is by far the best I have encountered but it does have some problems. All my experience is on V7. Lately it crashes way too often, it almost always crashes when closing. This is a problem when I have updated a Device Set Preset-my latest updates are lost. Clicking the X on the big window or the Workspace window gives a rotating blue circle and then the big window closes after a few seconds. I use the ? often but it often fails. AirSpy main window does nothing when ? is clicked. Spectrum Marker dialog and several others yield a red circle with a slash through it. Please tell me what saved information may be useful for debug. Thanks much. Enjoy, John.

What features / channels do you have open when it crashes? A screen shot might help. It may be related to: https://github.com/f4exb/sdrangel/issues/1295

Preferences > Configurations > Update button should save the config before you exit.

AirSpy main window does nothing when ? is clicked.

The link for this is missing. I'll add it.

Spectrum Marker dialog and several others yield a red circle with a slash through it.

Can you post a screenshot showing this please?

I also have problems with blocks and slowness especially when displaying and using 3D maps (especially with the Ubuntu version). My Internet connection is OK. But I think the power of the PC must be high to be able to use SDRangel in the latest versions (v7.4.0). What type of PC configuration do you recommend (RAM, number of cores, clock frequency ...) ? My current PC must be too old... (Google traduction)

Spectrum Marker dialog and several others yield a red circle with a slash through it.

I cannot take a screenshot of the "no way" sign that appears but I think it is when the "?" is clicked in the top bar of the system dialogs like:

I don't know how a link to a web page can be inserted there... Or the "?" be removed.

Edit: it appears that QDialog has the context help button (the "?") by default.

[srcejon]

In HttpDownloadManagerGUI I get rid of it with:

    Qt::WindowFlags flags = progressDialog->windowFlags();
    flags |= Qt::CustomizeWindowHint;
    flags &= ~Qt::WindowContextHelpButtonHint;
    progressDialog->setWindowFlags(flags);

If you want to handle clicks, stackoverflow suggests https://doc.qt.io/qt-5/qwidget.html#nativeEvent

It seems it's Windows only - so if we did want to add context sensitive help - probably better to do in a cross-platform way.

[f4exb]

Or:

setWindowFlags(windowFlags().setFlag(Qt::WindowContextHelpButtonHint, false))

Handling the event seems a bit complex for things documented elsewhere.

[srcejon]

You might need Qt::CustomizeWindowHint as well.

[mistergitj]

I will investigate and try all the suggested solutions soon. It does not seem to matter what Channels/Features are being used. I will post a screenshot as best I can. I also found I could not get a SS of the red circle/slash but will post a picture.

choupette-change, when I bragged about my machine having 16 cores capable of running 32 threads, I was told that the current V7 does not multi-thread. Right now I am running ADS-B and seeing 23 threads running: Thanks much for all the quick response. Enjoy, John.

[srcejon]

I was told that the current V7 does not multi-thread.

V7 is multi-threaded - I was referring only to one function within the Radio Astronomy plugin that you was having problems with.

I also found I could not get a SS of the red circle/slash but will post a picture.

It's OK - I think we understand this problem without the need for a screenshot

"What features / channels do you have open when it crashes? A screen shot might help. It may be related to: https://github.com/f4exb/sdrangel/issues/1295" I really do not think the Features/Channels in use makes much difference. Recently I was using Radio Astronomy and ADS-B which almost always crashed on close. I was doing some frequency calibration and running either no Channels or the Noise Figure and experienced the crash.

"Preferences > Configurations > Update button should save the config before you exit." I do not understand. The Preferences-Configurations is blank. I am to click Update with nothing selected?

Thanks much and enjoy, John.

It does for me on Windows but not on Linux (Ubuntu 22.04). On Windows the segfault appears right after DeviceGUI is destroyed:

Thanks much, f4exb. I was afraid of that. I will look in my system log and post what looks relevant. Enjoy, John.

Thanks and enjoy, John.

I have discovered that if I do not Start the SDR, then I can close SDRangel with no crash. But if I click Start button, then SDRangel crashes every time on close. The Channels/Features running have no effect. Thanks and enjoy, John.

[mistergitj]

Initial testing of 7.5.1 indicates it has the same problems for me as previous versions. Thanks, John.
