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.

AirNav 1090 Dongle RTL Based?
https://github.com/szechyjs/dsd this will decode Dstar, I haven't used it for many years but it did work on my computer.
- Automatic Digital mode detection and decoding

Is this encryption or frequency hopping or just not FM modulation? Not law enforcement, just a school they use Motorola handhelds.

Command line Linux DRM decoders
I have searched DSD only, but it can't stream audio to Icecast server.

Problem with piping audio
I use DSD.
- Decoding DMR at MacOS

Having trouble following tutorial
https://github.com/szechyjs/dsd/wiki/Installation Just install it from the repository. sudo apt-get install dsd
-
What am i doing wrong??
there is native DSD implementation https://github.com/szechyjs/dsd

Adding CFLAGS to a makefile
For DSD, this one is the most likely project I found. I don't have time to track down the prereqs right now, but if that's the project you're looking at, the Makefile would be generated by CMake, and I'd hope that an up-to-date version of CMake would output a Makefile with appropriate CFLAGS for the version of compiler.
