You need to find the binoculars. Many FFA maps have them to pick up. Then you can use them like in single player with sound and radar tag.
In mp_monkeybay, they are on a box in the middle of the walkway over the water. Look right and down when you are at the monkey statue.
In mp_radio there are two pair of binocs. One in the turret with the M4 and the other on boxes stacked near the central building near the fence.
