− | ==CHARLES COUNTY PUBLIC SAFETY RADIO SYSTEM==
| |
− | Charles County Public Safety is a Rebanded 800 MHz System Motorola Type II(2) <br>
| |
− | with Digital Audio & Moto ID's, to use a scanner to listen you will need <br>
| |
− | several of the setting displayed in this page. All regular TGID's are displayed <br>
| |
− | on the regular RRDB, this page list the Motorola ID's and Channels. Currently there <br>
| |
− | is no way or any legal way to decrypt their encrypted ;communications, all other <br> communications are in the free and clear. If you program or download the Encrypted <br>
| |
− | channels you will either slow the scanner down with an additional TGID that's <br>
| |
− | unnecessary, or hear a digitally encrypted audio signal, or your scanner may mute the<br> digitally scrambled audio altogether, unless you are recording hoping to decrypt the <br> communications in another 10-20 years, it is virtually pointless to even enter them <br>
| |
− | in even a Motorola handheld or base unit without the proper "KEY" cannot decipher the <br>
| |
− | Encrypted communications. Digital End codes is not used, AGC setting on Digital and <br>
| |
− | Analog make motor-boating a prevalent issue.

| |
− | SCANNER BAND PLAN SETTINGS on some model have to be set-up to receive transmissions, since the 800mhz frequencies were rebanded in 2012, without the Band Plan set correctly then some scanners will no long understand where the channels(Motorola/TGID's) are
| |
− | since they moved from frequency range of 861mhz-868mhz down to the 851mhz range.
