Abstract
Two FM receivers with a common audio output each with its own antenna located six to fifteen feet apart are provided for a moving vehicle together with a switching circuit that in response to the AGC signal sensed at the output of the multiplex adapter of each receiver selects a first receiver if the AGC of that receiver is of greater amplitude than a threshold signal or the amplitude of the AGC signal of the other receiver.
