All transmissions must be identifiable by identification signals or other means, though for some systems, space systems among them, signals are not always possible (19.1, 19.1.1); transmissions with false or misleading identification are prohibited (19.2); amateur, broadcasting, fixed below 28 MHz, mobile and standard frequency services should carry identification, radiobeacons must, and 406-406.1 MHz satellite EPIRBs must (19.4 to 19.11); identification is given as often as practicable and at least hourly (19.17); administrations ensure that transmissions without identification signals that can cause harmful interference abroad are identifiable by other means and adopt measures to that end (19.26, 19.27); defence stations may be identified by national measures but should use recognizable call signs (19.28).
