The Most Common Codes Here they are: 10-4: affirmative, ok, received, 10-2: radio – good reception, 10-15: arrested, 10-12: standby and 10-9 means the cop is asking dispatch to repeat the last message sent. Other common codes are the following:
10-8: back in service, 10-7: out of service, 0-6: busy and 10-20: location. You will also hear other codes that are used such as 10-28, checking a license plate, 10-38 criminal record, 10-51 accident and ambulance is needed, and 10-97 means the cop is on the scene. Signals This is just the same as the codes but rather than actions it emphasizes events. The most popular signals are the following: 10-20: location, signal 53/63 – check up a home or building, signal 40 stop for a second, while standby means hold on and copy means you need to be prepared for a call. Code 1 means en route while code 2 means urgent, and 10-12 means the question being asked is are you on standby? What are Police Scanners? A police scanner is a device designed to let you listen to conversations by policemen and dispatch. The simplest way to think of these scanners is that they work like FM/AM radios. Those gadgets pick up the frequencies transmitted by music stations that allow you to tune in and listen. That is the same principle that is used by police scanners. The only difference is that instead of music stations, the scanner picks up the frequencies reserved for cops, firemen and other emergency personnel. These scanners are usually programmed with channels that allow the people who buy them to tune in. Most of them also have features like search, allowing you to pick up frequencies that are not yet programmed in the device. The early models made use of quartz crystals to manage the frequencies but were limited in the number of channels that they can provide. That is no longer the case though as modern devices have plenty more channels and features. It is also worth pointing out that there are different types of scanners now. For example, some of them are portable so you can bring it with you anywhere you want to go. Furthermore, these devices can also be set for the desktop. These are not portable but they have more features and are more powerful. There are also a growing number that are now online, so as long as you have Internet access you can use the scanner. For someone who does not know anything about police scanner codes, all the numbers they use in conversation except 10-4 will not make sense. But the information given above will help you understand what they mean. By Kate – Anyone who has been watching TV shows will realize that cops use certain codes and signals when they are on the radio. While it may seem complicated, these codes are actually easy to learn. Get insights into police scanner codes and what those codes and signals mean.
