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.

message hidden in video from an obscure challenge
I have little experience with decoding radio signals so I don't know if any software decoders are expected to handle the clipping. I tried using multimon-ng and found that its UFSK1200 demodulator can get something out of the audio, but it also keeps repeating Error: stop bit is 0. Bad framing if verbose mode is enabled.

why am I getting no pages on PDW? I have set EVERYTHING up as per the instructions. I have played with all the settings. nothing
Sorry I gave wrong name, it is multimon https://github.com/EliasOenal/multimon-ng and is capable to decode:

Questions regarding POCSAG receiving
It's likely that the signal is extremely strong. You can probably just pick it up with a short antenna indoors. I used MultiMonNG to decode. It's was pretty boring to be honest.

Pocsag decoding
Give multimon-ng a whirl. This is CLI based, but can output what it decodes to a simple text file or hex data to do what you need with.

A list of things I could do with SDR
POCSAG, FLEX (pagers), Morse, APRS and more with multimon-ng

What OS has the best software for RTL-SDR? I currently use gqrx but feel its limited.
multimon-ng for decoding various protocols.

Pager messages
Try this tool; https://github.com/EliasOenal/multimon-ng - It's CLI and you'll ideally want a Linux, but this can decode an awful lot more data modes like such.

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++ and flrig running on Mac M1
SDR++ from GitHub (https://github.com/AlexandreRouma/SDRPlusPlus) runs on M1
- SDR++ (Android) Frequency Manager will not import or export

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?

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.
What are some alternatives?
