Which amateur stations may make contact with an amateur station on the International Space Station using 2 meter and 70 cm band amateur radio frequencies?

The correct answer indicates that any amateur radio operator holding a Technician class license or a higher class license is permitted to make contact with an amateur station on the International Space Station (ISS) using 2 meter and 70 cm band frequencies. This is governed by the rules of amateur radio that allow licensed operators to communicate across various bands, including those specifically designated for amateur use.

The 2 meter (144-148 MHz) and 70 cm (420-450 MHz) bands are commonly used for local and repeater communications, as well as for special events like those involving space stations. The ISS operates special amateur radio stations that are accessible to licensed operators.

Amateur radio is designed to be an inclusive hobby, encouraging participation from anyone who has obtained the necessary licensing. Thus, all amateurs with at least a Technician class license are authorized to make these contacts, regardless of affiliation with NASA or any other organization. This availability fosters communication skills, sharing of space information, and can even inspire people through learning about amateur radio and space exploration.

In contrast, the other options incorrectly restrict access based on affiliation, personal connections, or suggest that contact is not possible at all, which contradicts the open nature of amateur radio communication as regulated by the Federal Communications Commission
