The purpose of this page is to inform the user of the different types of scrambling systems, and where they are being used in the Lane County, Oregon area. The only intent is to familiarize the serious scanner listener with the different types of sounds emanating through their radios and who uses them. Please do not ask for any information that would assist in defeating these systems. I will not provide any nor do I know of any. Sample sounds below are slightly modified from their original recordings. |
