Which types of radio services are prohibited for CAP business?

The correct choice highlights that amateur radios and general radio services are prohibited for CAP (Civil Air Patrol) business. This is primarily because these types of radios are not specifically designed or licensed for the operational and communication needs of CAP activities.

Amateur radio services are meant for personal use and do not adhere to the same operational standards required for organized emergency communications, which CAP requires. General radio services, while more versatile, also do not provide the level of reliability, regulation, and accountability needed for CAP operations.

In contrast, family radio services, though they can be used for personal communication, are not typically referenced in the exclusion for CAP business, focusing on amateur and general services instead. Therefore, focusing on these two categories emphasizes the legal and procedural boundaries that CAP adheres to in order to maintain the integrity and safety of their missions.
