| − | ==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 nor for other trunk types. 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. On the RRDB, these frequencies are marked in <font color=red> red</font> for the primary control channel, and <font color=blue> blue</font> for any alternate control channel. Be sure to program both primary and any alternate control channels.

| |
| − | 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)
| |
| − |
| |
| − | * '''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)
