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?

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.

Create a subghz file from known data?
For example, rtl_433 has the spec for an X10 sensor say I know what data I want to put where, is there some tool/site I could enter in what the "specifications" of the signal waveform are and the data I want to send as a byte-string or binary-string and it would create a playable .sub file for me?

New Guy: Outdoor Thermostat / automated fan start/stop.
For "outdoor distances" I'd probably stick to something LoRa or 433MHz based. YoLink has quite a few options using the LoRa protocol. I use basic 433Mhz based AcuRite sensors paired with an RTL-SDR dongle connected to a machine running RTL_433, and use Home Assistant to trigger automations and alerts.

Mystery signal?
866-868MHz is SRD/ISM band (in UK/EU). Can be things like energy meters, TPMS, medical devices etc. Try rtl_433 on it.

Problem trying to listen to a Honeywell doorbell (RF 868 Mhz) with RTL-433
I'm trying to add a Honeywell doorbell to Home Assistant by using the RTL-433 GitHub project/program. When I run the program the SDR dongle is detected but it doesn't display anything when I press the doorbell (the image shows what I see after running the program and pressing the doorbell). I have also tried Honeywell Activelink (FSK) aka [116], so I have tried both 115 and 116 decode protocols.
