The communications feature allows the installation to receive and transmit on a wide range of radio and TV bands, monitor police and emergency channels, coordinate communications between members of a team, and so forth. It includes communications equipment, consoles, and monitors. The system’s access to restricted communication bands depends on the clearance and skills of the user. Heroes often have access to special government channels, while a successful Technology skill check (DC 25) can grant a user illegal access to restricted systems.
