Which statement best describes the USA-INT function on duplex channels?

Explanation:
Duplex channels are meant to work with repeaters, using separate frequencies for transmit and receive. The USA-INT function, when enabled, allows those channels to operate in simplex mode, meaning you can transmit and receive on the same frequency (direct, without using a repeater). This is why it’s described as converting duplex channels into simplex. It doesn’t increase range or convert simplex back to duplex.
