Apparently the FCC does not need a warrant to perform a search of a radio users equipment. This youtube video I came across explains how it works. https://www.youtube.com/watch?v=e4AeX7fsd6E
I emailed a repeater owner before my last road trip. He responded within a couple of hours letting me know the repeater would be down during my time in the area. He was finishing up some upgrades and testing, but would let me know when it was back up.
