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.

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!

'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.

SDR over Ethernet - Anyone tried it?
A network protocol called rtl_tcp that has been ported to rsp_tcp by the guys at SDRPlay in order to increase the IQ bandwidth from 8 to 14 bits to get the most from their SDRs. SDRPlay has provided a rsp_tcp server app/image that can be run on various hosts including RPi. Your RSPxx SDR connects to the RPi via USB and the RPi connects to your local network via Ethernet or Wi-Fi. Any network client application that supports rsp_tcp/rtl_tcp (including SDRUno) can connect to the RPi and use the SDR just as if it was connected via USB. This not only allows you to use your SDR from potentially anywhere you have a computer, it also allows you to minimize the distance between the SDR and the antenna(s). In theory you could even run Ethernet cable right up to the antenna.

How does sample rate work in an sdr
Hmm. I'd check out the RTL-SDR Sourcecode, in particular rtl-test, and manpage. This tool lets you calculates the PPM error of your dongle.

Raspberry Pi controlled radio telescope.
Not sure if it’s exactly what you want, but you can control GQRX over TCP. If you want more granular control, you can use the rtl-sdr library to process your desired signal. In my opinion it’s a bit low level for your project so using its Python wrapper, PyRtlSdr so you can get most of the rtl-sdr functionality while using Python’s networking.
What are some alternatives?
When comparing librtlsdr and rtl-sdr you can also consider the following projects:
