Which of the following amateur stations may transmit one-way communications?

FCC Part 97 generally prohibits amateur stations from transmitting one-way communications, which are typically associated with broadcasting. However, there are specific exceptions built into the rules for stations whose purpose inherently requires one-way transmissions. Space stations, beacon stations, and telecommand stations are explicitly allowed to make one-way transmissions. Beacon stations need to transmit continuous signals to help others observe propagation and radio frequency conditions. Telecommand stations transmit one-way signals to control remote objects, such as satellites or model craft. Other choices like local repeaters, linked repeaters, and message forwarding stations are designed to facilitate two-way communications between operators, even if the transmissions are asynchronous. Therefore, they do not fall under the specific one-way transmission exceptions.
