What is meant by the statement that a satellite is operating in U/V mode?

• A. The satellite uplink is in the 70 centimeter band and the downlink is in the 2 meter band
• B. The uplink and downlink are both in the 2 meter band
• C. The satellite's frequency is variable
• D. The uplink and downlink are in the same frequency band

Answer: (A)

When a satellite is described as operating in U/V mode, it specifically means that the uplink frequency (the frequency at which signals are transmitted to the satellite) is in the 70-centimeter band, while the downlink frequency (the frequency at which signals are received from the satellite) operates in the 2-meter band. This configuration is common in amateur radio satellite operations, as it allows for effective communication between ground stations and satellites. The separation of these frequency bands is beneficial because it helps reduce interference between the uplink and downlink signals, which can occur if both are operating within the same frequency range. By having distinct bands for uplink and downlink, operators can clearly identify and separate the transmissions occurring in each direction, making for more reliable communication and ensuring that multiple stations can operate simultaneously with minimal disruption.
