Question B-008-001-009

Two mobile stations are traveling along the same road in close proximity to each other and having trouble communicating through a local repeater. Why may it be necessary to use simplex operation to communicate between these cars?

Correct Answer

The strong signal of one mobile transmitter may desensitize the receiver of the other mobile receiver

Explanation

When very close, the strong signal from one car's transmitter can overload or desensitize the other car's receiver, even though they are on the repeater input/output frequencies.
