Configure your receiver

Read this explanation of the different classes and roles of receivers for decoding and voice following.

Configuring your Uniden scanner to provide control channel data:

  1. On the program's receiver window, be sure the receiver's role is set to "Signal".
  2. Program the system into the radio first. Use the radio's front panel menus or your favorite programming software to do this.
  3. The program does not automatically enable/disable CC data output. You'll need to set this yourself.
  4. Set CC data output to "ON", not "Extended". It is less work for the program to parse the data provided.
  5. Set the radio to Hold on the control channel. It must not scan or search while decoding.

This last step is important. If you hear voice from the radio while decoding, the radio has left the control channel. This cuts off the continuous supply of control data to the program. This event is indistinguishable from a lost signal event and may force the program to re-acquire the site / system.


When the program first acquires the control channel of a site - it does not have a way to reliably match that signal to a previously logged system. It creates a new site/system and logs information to that new site. In the call activity panel the program will display "Frequency needed" next to the control channel. Enter the radio's control channel frequency here. Click on the frequency, press "F2", and type the frequency in Mhz. Press enter or click the "Apply" button on the toolbar.

The program will search for previously logged EDACS sites for one having the same site number, LCN and frequency. If a match is found, the program switches to that site, discarding the "Limbo" site/system.


The program does not (and should not) create a new system each time you start the program. It will create a new "Adhoc" site with site number zero. This site will be tied to the system ID. If you've entered talkgroup and/or radio ID labels, they will be displayed in the call activity and call history panels of this site. If the site is networked, the program will eventually discover the site's identity and create a new (or match an existing) site with the correct site number. You can also manually enter the control channel frequency (as described above for EDACS) to expedite this process.

If you've logged a new Motorola system that turns out not to be networked - you can edit the site's label to replace the "Adhoc" text with something more meaningful. The RR DB download will usually provide a descriptive name.


The '996XT has two serial ports. The front port fits the factory supplied cable. That is the preferred connection for programming and Unitrunker decode operations. There is a second serial port - located in back - that is primarily for connecting a GPS for location aware scanning. You can also use this port with Unitrunker. You will need to make sure the program's baud rate matches this port. You will also need to program your radio to direct the CC control data to the back port instead of the front.
