To be honest: I keep hearing that PGP was / is difficult to use. That couldn‘t be further from the truth - but somehow it has become an urban myth. From the very first versions that I used on my first Mac up to GPG Mail or Proton Mail I never encountered any significant difficulties and could successfully exchange messages with my peers - both in business and private contexts.

Yes there absolutely are!
The EFF has the Rayhunter project at https://github.com/EFForg/rayhunter - it is basically an IMSI catcher catcher. You install it on a pocket router and it detects typical signatures that IMSI catchers use, for example telling your mobile to downgrade from LTE to 2G making it easy for them to tell your device to join THEIR network and read the IMSI / IMEI for your device and possibly route your traffic through their network.
The device with Rayhunter installed will notify you when these signatures are being detected and you get a pcap file that you can dissect using Wireshark.
There are other tools that you can install on Android devices but Rayhunter certainly is a good start if you want to detect the use of IMSI catchers.
One caveat: IMSI-catching is a cat-and-mouse game, so no promises can be made that the Rayhunter heuristics catch all attacks.

Is the hardware and software open source? Is there a link to a repo that I have missed?

However for starters I would stick with the more well known sources directly from Qwen or from reputable players like Unsloth:
Watch your Linux systems for kernel updates. Reboot!
