What is the effect of selecting the USA-INT control on channels that are normally duplex?

This question tests how a regional mode control affects duplex versus simplex operation. Some channels are set up as duplex so you can access repeaters by transmitting on one frequency and receiving on another offset frequency. When the USA-INT control is selected, those duplex channels are forced to operate in simplex, meaning transmit and receive occur on the same frequency. This removes the repeater offset and lets you communicate directly without a repeater. The control doesn’t change how far you can reach (range is tied to power and propagation, not this mode), and it doesn’t turn simplex channels into duplex.
