'''Control Channel Only (CCO)''' is available in selected makes and models of scanners, when trunking [[Motorola]] systems and [[P25]] trunking systems. For the older Uniden scanners that utilize [[banks and lists]] only 800/900 MHz trunking is supported; it is available on all bands where trunking is supported in the Uniden scanners that support [[DMA]].
  
 
CCO programming is recommended for use in selected RS scanners starting with the Pro-93 in bands where [[Motorola]] trunking is supported and this includes all P25 trunking bands for the Pro-96/2096 and the GRE PSR-500/600 scanners.  It enables the user to trunk a system by programming in only those channels that are utilized as a [[control channel]], instead of having to utilize memory to program the entire system.  This mode works for both analog and digital systems.

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. An example can be viewed [http://www.radioreference.com/modules.php?name=RR&sid=187 here] . In this case there are 4 control channels; 2 primary and 2 alternates.   
+
In the RR database, frequencies are marked in {{color|red|RED}} with a {{color|red|(c)}} for the {{color|red|primary control channel}}, and {{color|blue|BLUE}} with an {{color|blue|(a)}} for any {{color|blue|alternate control channel}}. Be sure to program both {{color|red|primary}} and any {{color|blue|alternate}} control channels. An example can be viewed [https://www.radioreference.com/apps/db/?sid=187 here]. In this case there are 4 control channels; 1 primary and 3 alternates.   
  
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.

Older Uniden radios require that a plan be programmed, as well as all the control channels, for CCO to work. RS/GRE radios including the New GRE radios, as well as the newer [[DMA]] based Uniden scanners, do not require a plan. In addition, no plan is required when utilizing CCO in the 900 Mhz band.

Introduction

Control Channel Only (CCO) is available in selected makes and models of scanners, when trunking Motorola systems and P25 trunking systems. For the older Uniden scanners that utilize banks and lists only 800/900 MHz trunking is supported; it is available on all bands where trunking is supported in the Uniden scanners that support DMA.

CCO programming is recommended for use in selected RS scanners starting with the Pro-93 in bands where Motorola trunking is supported and this includes all P25 trunking bands for the Pro-96/2096 and the GRE PSR-500/600 scanners. It enables the user to trunk a system by programming in only those channels that are utilized as a control channel, instead of having to utilize memory to program the entire system. This mode works for both analog and digital systems.

In the RR database, frequencies are marked in RED with a (c) for the primary control channel, and BLUE with an (a) for any alternate control channel. Be sure to program both primary and any alternate control channels. An example can be viewed here. In this case there are 4 control channels; 1 primary and 3 alternates.

Notes:

  • If the control channel should change, and it isn't one of the ones programmed in the list, trunking using CCO will fail, possibly making your scanner go deaf on a system. You can thus think of this a "mode to flag if any new control channels suddenly become active in the system."
  • Harris Trunked Radio Systems may need all channels programmed since all can be the Control Channel

Older Uniden radios require that a band plan be programmed, as well as all the control channels, for CCO to work. RS/GRE radios including the New Whistler radios, as well as the newer DMA based Uniden scanners, only require a plan if it's an 800mhz rebanded system Motorola Type I or Type II. In addition, no plan is required when utilizing CCO in the 900 MHz band.

Hints and Tips

If you need to trunk a multi site system (particularly if you are mobile, and moving from the coverage from one site (a) to the next (b), programming a dummy channel (c) will allow the scanner to move to another site(a,b,d) better during inactivity from the current site(a). The following illustrates the programming:

ex. Site Frequency
(a) Site001 868.17500
(c) Dummy 1300.00000
(b) Site002 868.22500
(e) Dummy 13000.00000
(d) Site003 866.65000

The dummy frequency (e) could be any valid frequency that is unused in your area (free of signal). Programming a used channel (c), in this position, could interfere with normal trunking. This tip works with the PRO-96 and 2096. (Thanks to user "fmon" for the tip and suggestion for the writeup) and could possibly work for other makes & models
