"1) Build an ADS-B receiver using Raspberry Pi and Software-Defined Radio (SDR) to track aircraft in your vicinity.
2) NOAA Weather Satellite Receiver ... can capture and process high-resolution weather images.
3) Radio Astronomy: Detect and analyze radio signals from celestial objects, such as the Sun, Jupiter, or even pulsars. F
4) Build a trunked radio scanner using Raspberry Pi and an SDR dongle.
5) Create an Automatic Identification System (AIS) receiver with Raspberry Pi and SDR to track ships and vessels in your vicinity.
6) Radio Direction Finding (RDF) - locate the source of radio signals. This project allows you to determine the direction of signals and can be used for various applications, including locating interference or tracking down rogue transmitters.
7) Pager Decoding: decode and monitor pager signals.
8) Turn your Raspberry Pi and SDR into a microwave cooker camera to visualize microwave radiation.
9) FM Radio Receiver:  tune in to your favorite FM radio stations and explore the world of software-defined radio.
10) Create a GSM base station using Raspberry Pi and SDR to experiment with GSM networks and protocols. This project enables you to set up a miniature GSM network and explore cellular communications.
Please note that some projects may require additional hardware, such as specific SDR dongles or antennas ..."


10 Best Software Defined Radio (SDR) Projects:
" 1)  Receiving and Decoding Radio Broadcasts, including FM, AM, shortwave, and digital radio
  2)  Tracking Aircraft with ADS-B
  3)  Monitoring Weather Satellites, receive images and data from NOAA weather satellites.
  4)  Listening to Amateur Radio Communications (ham), including SSB, CW, and digital modes
  5)  Exploring Digital Radio Mondiale (DRM)
  6)  Analyzing the Radio Spectrum
  7)  Experimenting with Digital Modes
  8)  Setting Up a Local FM Transmitter - Create your own low-power FM transmitter (understand local transmission regulations!)
  9)  Building an SDR-Based Radar System - build a simple radar system for detecting objects
10)  Monitoring Satellite Communications


Fifty Things you can do with a Software Defined Radio: 
"A Software Defined Radio is essentially a radio that relies on a computer to do most of its data processing. It doesn't rely on analog hardware too much – instead, most of what is does is "defined in software", hence the name.
Usually, SDRs can detect electromagnetic waves in a much wider range than a common FM radio, which makes it especially exciting! "
"(By the way, there's another great option if you don't want to buy anything – lots of people make their SDR accessible through the Internet! You can find a map https://rx-tx.info/map-sdr-points)"
