sdrangel VS SDRPlusPlus

Can also try SDRangel which has integrated satellite tracker, rotator controller, and does 3D map overlay.

Try adding an issue with a screenshot here: https://github.com/f4exb/sdrangel/issues

Also, if you used the Satellite Tracker to start decoding, then you can open the 3D Map and have the image projected on to a 3D globe

See quick start page here: https://github.com/f4exb/sdrangel/wiki/Quick-start

I'm using newest SDR++ nightly built. win x64. Anyone can resolve this problem? Mabye I'm not using the right driver for SDR++? If so where can I find the right one?

SDR++ from GitHub (https://github.com/AlexandreRouma/SDRPlusPlus) runs on M1

Ah, I see what you mean, it's been a while since I looked at their repo. They don't seem to have one for ubuntu jammy yet in their stable release branch. But they do have an ubuntu jammy one in their nightly builds https://github.com/AlexandreRouma/SDRPlusPlus/releases/tag/nightly. I did give it a go and it seems to work okay, but obviously you would need to try it more thoroughly than I have.

What incompatibility? Do you think that this code https://github.com/AlexandreRouma/SDRPlusPlus doesn't support ARM?

Some software tips. There is a newer version of SDR++ that includes an IF filter for NOAA APT signals that should help improve things: https://github.com/AlexandreRouma/SDRPlusPlus/releases/tag/nightly That gives you a new checkbox under the Radio section called "IF Noise Reduction" with a dropdown to select the type of reduction (where you select 'NOAA APT'). You can also use the "Decimation" option in the Source section to give a bit better SNR. From what I've read you get a 3db reduction in noise every time you double the decimation level. If you can't get rid of the noise around 137.1MHz maybe try going for NOAA 15 or 18 since those are at higher frequencies, hopefully away from that noise.
