Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

RTLSDR V4 wrong frequency range
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++ on Mint?
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.
- Using direct sampling on Android Tablet! SDR++ is out for Android!!

Can someone explain how this script bypasses CPU architecture incompatibility?
What incompatibility? Do you think that this code https://github.com/AlexandreRouma/SDRPlusPlus doesn't support ARM?
- SDR++ is a cross-platform and open source SDR software with the aim of being bloat free and simple to use.
- Alternatives to soapyremote/CubicSDR?

What SDR app on Android is compatible with Airpsy mini?

Update on my NOAA reception adventure
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.

Receiving Weather Satellite Images Using SatDump
GOES sats are geostationary but the NOAA APT satellites are encircling the planet and you can pick them up. Old tutorial but still relevant, just use "noaa-apt" tool[0] instead of WXtoImg. https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat...

- Hi 2
- SDR# and NOAA Satellites
- Made a very simple 137 MHz dipole V antenna, made out of copper brazing rods and a terminal block and this is the first picture of NOAA 18 I got from it, also it picks up 250 MHz Satcom pirate transmissions rather well. Much better than my pa0rdt antenna which adds a bunch of noise!
-
Why the image is so small?
Sometimes WXtoIMG just discards parts of the recoding when the signal wasn't strong enough. In those cases I've had some luck running the recorded .wav file through noaa-apt to get the full image.

Images pulled with RTL-SDR antenna NOAA
so the NOAA_APT decoder link on your guide did not work properly, By chance did you mean this link https://noaa-apt.mbernardi.com.ar/?
-
At least as long as they're not using the dev container...
So far I only use it for noaa-apt program though.

WXtoImg not decoding images
Had this exact problem, the thing that I found is that GQRX records at the wrong sample rate, which WXtoImg can’t handle. However, https://noaa-apt.mbernardi.com.ar this utility did work for me. I’ll also note that WFM is the setting I use in GQRX, not AM

Does anyone know whats happening here?
You should try noaa-apt too, it usually gives better results for me.
