Abstract
A method and apparatus are provided for determining a particular transmitting station from which program signals are received and translated by a monitored receiver within a test area and including mobile receivers. A stored transmitter characteristic table includes a corresponding transmitting station identification stored with a predefined subarea of a plurality of predefined subareas within the test area for each predetermined tuned frequency of the monitored receiver. A tuned frequency of the monitored receiver is identified and the particular transmitting station corresponding to the identified tuned frequency is identified responsive to both the identified tuned frequency of the monitored receiver and the stored transmitter characteristic table. The identified transmitting station data is stored with time of occurrence data.
