"We need 50 of your best radio operators to go down to Puerto Rico." Yet, a key mode of communication -- one not reliant on infrastructure vulnerable to strong winds and flooding -- still crackled: the "ham" radio. There, ham operators work shoulder to shoulder with public safety and utility officials to transmit information to other ham operators working with teams in the field. For instance, ham operators riding with police use radios tuned to the special broadcast frequencies to transmit calls to other ham operators hunkered down at the command centers with officers, who in turn respond with orders. Raul Gonzalez and Jose Santiago work to maintain the communication infrastructure they set up between ham radio operators in the Monacillo Control Center.
