The RTL-SDR is a cheap, powerful software-defined radio dongle that is popular in the hacker community. While it can be annoying to set up, using it on an Android device is free and surprisingly easy. Once set up, you can listen to radio conversations from a wide range of radio frequencies. Police dispatch traffic, hotel cleaning crews, first responders, and others use sub-megahertz range to communicate, and many of those remain unencrypted channels you can snoop on.

Parts needed:

- Android phone
- RTL-SDR dongle with antenna: https://www.amazon.com/RTL-SDR-Blog-R...

Either one of these, depending on your phone:

- USB-C OTG Adapter: https://www.amazon.com/Anker-Adapter-...
- Micro-USB OTG Adapter: https://www.amazon.com/UGREEN-Adapter...

Or, if you need power too:

- USB-C OTG Adapter with Power Hookup: https://www.amazon.com/Charging-Thund...
- Micro-USB OTG Adapter with Power Hookup: https://www.amazon.com/DSYJ-Micro-Sam...

If using the power OTG adapter, this would also be good:
