Police Scanner Codes

The past of the police scanner goes clear way back to 1930's. The police will broadcast over an AM radio Station. Anyone w/ a radio can hear the calls. A radio system is full of frequencies. Frequencies are the communication channels.

For you to be able to hear transmissions you should program channels to the scanner. The initial kind of police scanners are crystal controlled w/ about 4 channels. To hear transmissions you would have to get a quartz crystal tuned to the frequency and put into an inner slot. Each of these crystals is around 7 dollars and become very costly to upkeep.

Then in the 1970's police scanners that are programmable were made. It has a keypad that you will enter frequencies and the scanner memory would store all your frequencies. After that the trunked radio system has been introduced and it permitted you to save 5 to 30 frequencies or channels. A controller is where consumers were automatically allocated frequencies. Like the emergency sections would have 1 trucker or frequency would have some other frequency. These kinds are harder to check because you're usually changing channels in between conversations.

They were introduced in 2002 by "Uniden" and then in "2003", Radio Shack introduced their digital scanner. These are good to utilize because you could say things through the radio and it can't be heard, but simply by those who could decode it, which will be several individuals. The only persons who can decode the codes are those who are professional for the channel.
