Possibly. I doubt that they would reallocate their system wholesale, however. Do the math; if none of the adjusted freqs have a really horrible sounding data stream on them, you can assume that Kauai has not yet rebanded.
On second thought - didn't I read somewhere that they were moving from a LTR system to a P25? If they weren't on 800 before, save yourself some grief - use the FCC search tools in the database. Again, far simpler than just doing random searches
