You normally listen to the outputfrequency, as it can generally be received from a much farther range. Sometimes, though,you might want to know if the mobile unit is nearby. To do this, check the input frequency bypressing RVRS. If you hear the transmission, then the mobile unit is probably within 2 or 3miles of your location.21
