What does operating a transceiver in "split" mode normally mean?

The radio is operating at half power
The transceiver is operating from an external power source
The transceiver is set to different transmit and receive frequencies
The transmitter is emitting a SSB signal, as opposed to DSB operation

The correct answer is: The transceiver is set to different transmit and receive frequencies

Operating a transceiver in "split" mode refers to the configuration where the device is set to different transmit and receive frequencies. This mode is commonly used in amateur radio, particularly in situations such as DXing (making long-distance contacts) and contesting, where operators need to listen to one frequency while transmitting on another. In split mode, the operator might listen for incoming signals on a frequency that is different from the one they are using to transmit, often because there is a pile-up of signals and they are trying to work a specific station. By separating the receive and transmit frequencies, it helps manage frequencies more efficiently, reduces interference, and allows for clearer communication among multiple stations. The other options pertain to different functions of a transceiver. For instance, operating at half power relates to power output settings, using an external power source indicates the power supply method, and emitting a SSB signal specifies the type of modulation being used. These features are unrelated to the split operation of transmit and receive frequencies.
