Security tools like Flipper Zero are essentially programmable radios, known as Software Defined Radios (SDRs), a technology which has existed for years, and in some cases can be built using open-source or simple over-the-shelf-components.
That’s my local university; I listen to it all the time. It’s awesome to just listen to things from god knows where, knowing that it bounced around basically half the globe to reach me.
The tech itself is also really cool. You can have hundreds of people all listening and tuning to their own frequencies, all at the same time.
SDR is really cool:

SDR? I thought it just had a CC1101 for sub-GHz digital and an NFC/RFID module? CC1101 is very flexible but it doesn’t do direct IQ sampling.
