A Guide to Get UniTrunker Up and Running


DISCLAIMER and NOTE:

The images on this page are from UniTrunker V1.0.0.11 and the instructions are geared for users of the GRE PSR-500, PSR-600, PSR-310, PSR-410, PSR 700, PSR-800 and Radio Shack Pro-106, Pro-107 and Pro-197. Others can follow this guide but will have to make allowances for the type of scanner used which will provide the feed of the Control Channel Data Stream. The instructions are also geared to a Motorola Type II 800 MHz trunked system. After reading these, you should be able to adjust things to suit your particular circumstances.

The current preview versions of UniTrunker support the use of inexpensive (approximately $15) RTL-SDR dongles to receive the trunking channel data. This allows people to use the program without having to tap scanner discriminators or tie up expensive newer scanners to dump control channel data. Users have been successful in using multiple dongles to function as both control channel receivers as well as voice channel receivers.

The steps in this guide were actually used to get UniTrunker up and running with a PSR-600 as the data stream input device. The procedure may be different for other model scanners so users/visitors to this page are invited to make corrections or additions.


UniTrunker will also work with the following Uniden Scanners: BCT15X - BC346XT - BCD396XT - BCD996XT


Check the UniTrunker site periodically for the latest version of the program. These instructions should give you enough info to get you started. Latest version as of July 27, 2014 is 1.0.28.4. The latest preview version as of July 27, 2014 is 1.0.28.4.



Options

Download the UniTrunker program to your computer and make sure you have a connection to your scanner to receive the feed from it to the computer. Those using GRE-500/600s or their RS clones will use the same cable used to program the scanner. Run the software and you will find the screen below to open first. If it does not, click on the Options tab at the bottom of the page.

Go down the page to Motorola and make sure it says Decimal for Display Mode. If it does not, just click on Display Mode > click the drop-down menu and select Decimal. Click on 800 MHz > Click the drop-down menu > select Rebanded (if you are in Utah, otherwise you might want to select North America).

Go to the right scroll bar and drag it to the bottom. You will see a place to enter the UniTrunker URL (as shown) and the next line down enter the URL for Radio Reference (also as shown) and then your log-in credentials.


Receiver

Click on the Receivers tab to open this page.

Clicking on the "+" sign creates the line for you to enter the type of scanner and other info needed. This image was taken using a PSR-600 which is using an inline feed and although it shows "PSR500" it is perfectly acceptable because, other than the case, the PSR-500 and PSR-600 are the same scanner.

Double click on the line showing Unconfigured (See line pointing to it).

You should now be able to fill in the info for the program to operate. Start with the Unconfigured box and work your way down.

Example for Uniden Scanner


If your using a scanner with a Discriminator Tap and you were using the Retro Version and want to change to the Windows version use the following directions:

From the Receivers tab, click "+". Double-click on the "Unconfigured" receiver. Set the receiver's Type to "Signal"; this will cause additional sections to appear - including Signal and Decode. For receiver model - type in something meaningful like "R8500". For receiver role - use "Signal". Leave the receiver "Run" state at "Stopped" for now. Under the Signal section, fill in the settings comparable to your Unitrunker Retro configuration. Sample Rate of 44100, 48000 or 96000. Sample Size of 16 bits is recommended. Channel of "Mono" is good - unless you were using something different in Retro. Leave the Decode and Feeds sections alone for now. Go back to the receiver "Run" state and set it to "running". Click on the "Scope" tab to see the waveform. Adjust recording level according to instructions on the Unitrunker site.

The current version of UniTrunker gives a button window with receiver options (shown below) when you press the add receiver button. Much of the configuration is pre-done by selecting the appropriate receiver type. For a discrminiator tapped receiver, select "Signal". For an inline receiver such as the PSR600 select "Inline". If using an RTL dongle as a receiver select "RTL2832".

Place scanner in proper mode

To set your scanner in the analyzer mode, press the TSYS soft key (F2) on the front of the scanner. Then press the Analyz soft key (F3) on the front of the scanner and using the 5-way key, scroll up or down to find the Control Channel you wish to watch. When you stop scrolling, that will put it in the proper mode to run the Control Channel data stream to the UniTrunker Program.


Start UniTrunker Running

Once you have verified each line in the particular receiver's window is filled in correctly (most of this should have been auto-filled when you selected your receiver type previously), you can click on the start arrow or stop square on the toolbar to start or stop the receiver. The UniTrunker program should now be receiving the data stream from the System Control Channel that you selected on your scanner. Make sure your have the right Com Port selected! Additionally, from the main UniTrunker window, you can select the receiver and click on the start or stop buttons on the toolbar here to start or stop a particular receiver.

Receiving

After about 10 to 15 seconds, you will see this screen and you should start seeing activity as TGs join and leave the program. To stop the program, click on the icon that looks like a Radio and the pop-up will return so you can move from running to stopped by clicking the "running" box. The text in the Audience Column can be imported from RadioReference.

At this point, you should be up and running!
