− | ==Control Channel Only (CCO) Mode==
| |
− | This mode is available in selected RS and Uniden models when trunking [[Motorola]] systems in the 800 or 900 mhz bands.
| |
− | It is not available for trunking in any other band. It enables the user to trunk a system by programming in only those
| |
− | channels that are control channels, instead of having to utilize memory to program the entire system.
| |
| | | |
− | Note that if the control channel should change, and it isn't in the list, trunking using CCO will fail. You can thus
| |
− | use this mode to flag if any new control channels suddenly become active in the system.
| |
− |
| |
− | Uniden radios require that a plan be programmed, as well as all the control channels, for CCO to work. RS/GRE radios
| |
− | do not require a plan. The status of the upcoming GRE radios is unclear as of this writing. In addition, no plan
| |
− | is required when utilizing CCO in the 900 Mhz band.
| |
− |
| |
− | The following scanners are known to support CCO:

− | ==Uniden Plan Information==
| |
− | For those radios that require a plan to use CCO, there are 4 possibilities;
| |
− |
| |
− | * '''PLAN 1:''' if the last three digits of ALL the frequencies in use end in one of the following
| |
− | three digits: 125, 375, 625, or 875 (example: 856.1125, 860.7375, 859.6625, 855.8875).
| |
− |
| |
− | * '''PLAN 2:''' If ALL the frequencies are less than 869.0000 and end in one of the following three digits
| |
− | (125, 375, 625, or 875) and if ANY other frequencies end in (000, 250, 500, or 750) use Plan 2.
| |
− |
| |
− | * '''PLAN 3:''' If the last three digits of ALL the frequencies in use end in one of the following
| |
− | three digits (000, 250, 500, or 750)
| |
− |
| |
− | * '''PLAN 4:''' If ALL the frequencies are less than 866.0000 and end in one of the following three digits
| |
− | (000, 250, 500, or 750) and if ANY other frequencies end in (125, 375, 625, or 875)
