Which of the following connections is made between a computer and a transceiver to use computer software when operating digital modes?

The connection between a computer and a transceiver for operating digital modes typically involves sending audio signals from the computer to the transceiver. By connecting the computer's "line out" to the transceiver's speaker connector, you allow the transceiver to receive audio signals generated by the computer software. This setup enables the transceiver to process these signals for digital mode communication, such as RTTY (Radio Teletype), PSK31, or other digital modes.

The speaker connector of the transceiver is designed to accept audio signals directly, making it suitable for transferring sound output from the computer. Essentially, this connection allows the computer to communicate effectively with the transceiver, enabling the use of various digital modes efficiently.
