 SCP-724 is an anomaly covering approximately 8 meters in diameter. It occurs only when all of the surrounding radio towers, designated SCP-724A through SCP-724-1, are broadcasting actively, and when the signals from these towers are able to reach the anomaly's location without significant interference. While SCP-724 is active, any individual of the species Prokion-Lotor, North American Raccoon that passes through the anomaly is permanently altered by unknown means. Altered subjects, collectively designated SCP-724-1, begin to frequently produce abnormal vocalizations, including human voices, music, static, modulation and demodulation signals, and data expunged.
