What is the term for switching from a duplex to a simplex radio channel?

Explanation:
Talk-around describes bypassing the repeater to communicate directly on a single frequency. In normal operation, a duplex setup uses a repeater to relay signals (two directions on different frequencies). When you switch to talk-around, you’re moving to a simplex link, meaning you and the other radio transmit and receive on the same frequency without the repeater. This is handy when the other party is within direct range, when the repeater is unavailable, or you want to avoid congestion on the network. So the action of switching to that direct, one-frequency link is called talk-around.
