While not a physical radio, a Linux phone such as the Librem 5 in conjunction with an RTL-SDR dongle and external antenna may be a good candidate for a mobile software-defined radio (SDR) transceiver.
SDR frameworks such as GNUradio or REDHAWK are well-established by this point. Newer versions of REDHAWK are designed to run on CentOS/Rocky Linux, however, and they don’t (AFAIK) come with a mobile-friendly UI.
I do know that there are some web-based SDR tools in the wild. I’m not very familiar with them, their system requirements/capabilities/limitations, but they could be worth a look to jump-start a Progressive Web App for mobile devices.
GPS works anywhere on earth and doesn’t require a cell connection, it even works in airplane mode, so you really can’t get lost if you have the maps app (which you probably do)
Mapping apps like Magic Earth are a lot faster than Google Maps, especially when outside good cell coverage, and it’s easy to download maps in advance for wherever you’re going to be.

IF you have the local maps downloaded.

Or basically any Android with OTG support. There’s a bunch of SDR software also available on Android. SDR++, SatDump, SDRAngel, Welle.io, Dump1090,…
But obviously, a proper GNU+Linux phone will do better.
you can listen to encrypted radio transmissions this way with the correct codes and software of course
stop sharing police technology bro /,$
