What really happens when a scanner scans – what happens when if “finds something”?
Usually, scanners work pretty much like the radio in your car. The radio in your car probably has a “station seek” mode, where you can push a button, and it will slowly move up and down until it finds a station broadcasting. Then it stops and plays that station for a few seconds, and if you don’t stop it, then it starts scanning again until it finds another broadcast. Radio scanners work the same way, although often you can control how long they pause, how “much” of a signal will cause them to stop, and a variety of other additional features. Most scanners also support both a “frequency scan” and a “memory scan” mode. In frequency scan mode they work like the car radio – all frequencies between the end points are scanned, and anything it finds will cause it to stop and play. In memory scan mode, a scanner “jumps” from one stored frequency to the next, avoiding anything that isn’t “on” a stored frequency. Both modes can be useful for locating and troubleshooting RC RFI issues.
