NOTE: These frequencies have been obtained from FCC records and other public sources. We do not list tactical or surveillance frequencies for security reasons. It is not our position to present municipal communications systems. Please contact individual cities directly for their monitoring information. It is very easy to misinterpret something you hear on a scanner. St. Charles County does not encourage any citizen action based on information obtained by monitoring. Remember, federal law prohibits you from divulging the contents of what you hear, using any of the information you hear to commit a crime, or using any information you hear for personal gain. You may be arrested for interfering with a public safety official performing their duty if you elect to go to a scene. Do not go to an incident scene unless it is your job to be there and you were called specifically. You may not record, rebroadcast or webcast any St. Charles County system without the express written permission of St. Charles County Government. You may not transmit on any St. Charles County frequency unless you are an authorized volunteer or employee of the County or of a participating public safety agency and are using FCC "Type Accepted" equipment.
