While using the handheld receiver the static sound that is heard through the channel can get bugged to have a "dupe" replay. When the 9V battery was spent on my radio, the static sound of the void continued to persist even without a working battery. After I put in a fresh battery and turn back on my radio, this would cause a 2nd layer of static sound that plays over the original. A "dupe" radio static. When the radio is turned off the "dupe sound" will sync with my action but there is still the original radio static sound that cannot be fixed without having to do a re-log.
