from Twitter - Providence FD and Warwick FD radio systems went down from midnight to approx 330 am - Providence FD units were told to use Backup Channel 1 (? 154.37?) - the area had high winds and rain overnight
I would expect a user of an 800 MHz trunked system to run 800 MHz backup channels. Perhaps it is one of the 7 conventional 800 MHz channels they are licensed on.
