Final answer:
Radio beacons typically transmit their identification in Morse code, which represents letters with patterns of long and short signals, except when voice transmissions are occurring.
Step-by-step explanation:
All radio beacons except the compass locators transmit a continuous Morse code identification in code except during voice transmissions. Morse code is a type of communication where letters of the alphabet are represented by patterns of long and short signals, often heard as beeps or clicks. This method has been traditionally used for navigation and communication by various means, including radio transmissions.
