Using SDR to make .CSV files for Wireless Workbench
https://github.com/AD-Vega/rtl-power-fftw can help. This can be easily piped for various outputs and works with GNUPlot off the bat. Use this on an Android based SDR for foxhunting and Signal seeking.

how can I find other signals to listen to?
I like to use rrl_power_fftw

Frequency hopping driveway sensor?
You could use rtl_power_fftw to better record the wider band over a time period. This is similar to rtl_power from librtlsdr, but is more efficient and can dwell for as little as 100ms on any 2.4MHz window (24MHz done in 1 second, f.e.). You can then plot this data through GNUPlot to get visual representations.

Laptops with lowest RFI?
I have a rooted Android with an RTL-SDR attached, which I'd take with me if buying a new laptop. I'd sit near the laptop's on display with a stubby duck in the SDR and use rtl-power-fftw to rapid scan 27-1724MHz (fastest is 100ms dwell at 2.4MSps). Takes a minute or two and can be fed into GNUPlot to give you a pretty graph of signals seen. Do it at a low gain and any spikes you see are likely from those sources.

Passive signal collection?
Look into rtl_power_fftw. It can be run for hours on any host (including a Raspberry Pi) and the spectrum results examined later.

Rtl_power scanner logic
rtl_power_fftw is likely more well suited. It's multithreaded, so can sample IQ and process the data as it samples. It's also faster and uses libfftw for processing (faster and more accurate). Outputs more friendly, too. I use this in part with a signal heatmap project; https://www.reddit.com/r/RTLSDR/comments/ifer8j/progress_on_the_android_sdr_linuxdeploy_rtl_power/

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.
