If your laptop has a 2nd monitor jack, the easiest solution (and the prettiest) is to throw a 4:3 VGA 1200×1024 monitor on there. Amazon has ‘em for about $100, free shipping with Prime.

2) That makes quite a bit of sense. I’m currently running this on a laptop with a maximum screen resolution of 1366×768 and so the size of the spectrum display and waterfall are clearly being limited by the laptop’s limited resolution.

In response to your query I gave that key combination a try and the same result happened which that the “display setup” screen came up. I wonder what on Earth Windows is up to. I wonder if the keystroke is assigned to something in the OS and it is conflicting.

1) This seems to be a Windows thing; I duplicated it under XP, but not OSX. Windows (or perhaps the Windows version of Qt) is catching that control-D and turning it into just a “D”, even though I try to get the keystroke first. This *may* be configurable in your OS (it would be in OSX, so I’m guessing also in Windows… but don’t know. If it can’t be configured, I’ll just change the keystroke to something that works in Windows next time around… very shortly.)

2) There is some stuff in the docs, presently indexed under “aspect ratio” and “monitor.” I’ll go in there right now and add some other indexing choices that make sense for someone looking to get the spectrum and waterfall size under control… ok, done in the beta docs. It’ll show up in the normal online docs next update. Thanks.

So anyway, one direct adjustment is possible; that’s under the DSP dialog. You use the “2D Screen Size” setting to adjust the area percentage between the spectrum and the waterfall. This doesn’t set the area size; just the ratio between the two of the size. To set the size:

One indirect adjustment is possible; that’s done by adjusting the aspect ratio of the window. Seems odd, I know, but Qt insists upon resizing everything depending on window size and aspect, and so this turns into a way to adjust proportions. SdrDx, I find, is most pleasant to use on a 4:3 monitor, adjusted for about 1200×1024. On a widescreen monitor, it tends to shrink the spectrum and waterfall too far for my taste, unless you have enough resolution to shape the window into 1200×1024 within the widescreen window. You need a fair bit of native resolution to do that, though.

Thanks for your kind words. Fun for you = fun for me.

1) When I press CTRL+D to calibrate the S-meter the “display setup” windows comes up. I’m not sure why this happens.

2) How does one adjust the vertical size of the main spectrum display and waterfall? Currently the main spectrum display and waterfall are a bit too small. I read the documentation but at first glance I did not find anything.

Keep up the great work!
