    I’ve done quite a few hard shutdowns on my RPi with no consequence once I got the properly rated SD card. The only issues I’ve had was using the lower-rated SD cards, and it didn’t matter if I shut the Pi down properly or not.

    With a production repeater, it’s not that difficult or expensive to build in some power redundancy… I know a Pi can run a good while on AA batteries!

    A small UPS would be simple also to condition the power as well as provide backup power to other accessories. Some have USB connections on it. I am sure there is probably a Linux library out that that could interface with a UPS if desired and issue a safe shutdown when the UPS is reporting the end of it’s battery.

    This is another good idea, see what I’ve found with a quick google search on this topic:

    This project seems to be perfect for this use and it’s chaep.

    Thanks W5BFF for reporting your experience, I’ve executed also a number of hard shut downs with no issues, but of course before to put the repeater in production I would like to have some backup.

    Thanks! Mauro IW3ROW

    That seems to be a viable option too. As opposed to a UPS this will only provide power buffering to the PI where a UPS can support other devices if you need calls for that.
