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.

Radically different noise levels of different software and other noise reductions
Download the https://github.com/rtlsdrblog/rtl-sdr-blog or https://github.com/librtlsdr/librtlsdr version instead. Even try both, since there may be differences.
-
rtl_tcp for HF frequencies?
Give https://github.com/librtlsdr/librtlsdr a try?
-
Running rtl_power?
I should have mentioned, I'm using this fork of the librtlsdr library, which contains a slightly different version of rtl_power with some extra features, and apparently the "-D" option is treated differently in the version I'm using. The forked version allows you to set a specific branch using the "-D" option, as described below:
-
RTL SDR linux driver with full control.
There are a few variations of librtlsdr, f.e. this fork; https://github.com/librtlsdr/librtlsdr which adds features that aren't available in the version used in most Linux distributions. This adds some extra features and output that are really useful (most notably, regular output of max, min, mean power levels and noise floor). It also has some extra functions to fine tune signals.
-
Listen to DMR for free
Linux, librtlsdr and this port of DSD. FWIW, this port of DSD is newer and also has a Windows binary.
-
WBFM and nrsc5 using lightweight tools
Next I moved onto try feeding the output of rtl_sdr (from https://github.com/librtlsdr/librtlsdr) to nrsc5 and that worked well!
-
How to receive and record fm radio in stereo on the command line
You have an older librtlsdr; I'm using the GitHub version, which adds extra features; https://github.com/librtlsdr/librtlsdr

'rtlsdr_set_bias_tee' not found
Thank you for your reply, I have tried it with the 'static' from the official GitHub https://github.com/librtlsdr/librtlsdr/releases , but the error remains? Do you mean an even newer version?
- command line tool to search for local FM stations?
-
would I get worse performance by buying this nooelec clone instead of the real thing? the real thing is 10 bucks pricier and it also comes with a remote which i don't see myself using. https://www.amazon.de/-/en/RTL-SDR-Receiver-Antenna-RTL2832U-Software-blue/dp/B094ZJ3VVN/
github.com/librtlsdr/librtlsdr may be worthy to check out.

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.
