What does the designation "mode U/V" indicate about a satellite's operation?

The satellite operates only on VHF bands
The uplink is in the 70 cm band and the downlink in the 2 meter band
It uses both UHF and microwave frequencies
It operates under user-defined parameters

The correct answer is: The uplink is in the 70 cm band and the downlink in the 2 meter band

The designation "mode U/V" signifies that the satellite utilizes two specific frequency bands for its operations: the uplink frequency is in the 70 cm band (UHF), while the downlink frequency is in the 2 meter band (VHF). This is a common configuration for amateur radio satellites, allowing users to transmit their signals from ground stations on the 70 cm band and receive the satellite's signals on the 2 meter band. This dual-band operation is advantageous as it provides a means for effective communication in amateur radio, catering to the equipment commonly available to operators. It allows for established protocols and frequencies that many amateur operators are familiar with. Understanding these designations is essential for effective satellite communications and ensures that operators can access the satellite's capabilities as intended. The other options do not accurately describe the meaning of "mode U/V," as they either limit the satellite’s operational scope or inaccurately describe its technical parameters.
