Our TargetTrack and SignalTrack software packages provide map-based data from our direction finders. We recommend TargetTrack for use with our DDF7000 series radio direction finder (RDF) and SignalTrack for our legacy DDF6000 series equipment. In short, this page contains radio direction finder demonstrations and instructions on running playback for our RDF software. In addition, there are instructions on connecting with a fixed site radio direction finder. Visit our downloads page to download both software packages.

TargetTrack Play Back Demonstration

First, to view the operation of TargetTrack without a RDF, we’ve recorded two missions and created one training package.  We ran the recorded missions using the DDF7001 packaged systems near our office in Carefree, AZ.  The first mission is a single mobile unit searching for a beacon transmitter made by Big Red Bee.  The transmitter is programmed to send pure carrier for about 15 seconds followed by 30 seconds of silence.  The second recorded mission utilizes two fixed sites and one mobile site searching for the same transmitter in a different location.  The training package demonstrates the multiple target capability of TargetTrack.

To run the software demonstrations, download TargetTrack  This zip file contains instructions for loading the data and running the demonstrations.

Live Data Demonstration

(NOTE: The live site is currently off the air.  Please contact us if you would like a demonstration.)

Doppler Systems maintains a radio direction finder site in the Phoenix area that connects to the Internet.  Although we use the site for equipment and software tests, it is normally available to our customers.  If you would like to use this site, install SignalTrack or TargetTrack and download a map for the Phoenix area (press here to download). 


After you have installed TargetTrack, launch the software.  At the top of the map pane select Map Menu and select Open Map. Navigate to where you stored the “Area Around Phoenix” map and select it. Once the map is displayed, right click on the map near Carefree and select Add New -> Fixed Site.  Next, fill the dialog fields as shown below.  After you’ve connected to the site, use the receiver tuning control in the lower left corner of the window to tune the receiver to 162.55 (a local weather channel).  The site should display bearings slightly south of Phoenix (near the G in Guadalupe).  You can also tune to 162.425 which is another weather station on Mount Ord near Payson, AZ. 

TargetTrack requires audio streaming.  To set up audio streaming you will need to port forward port 10001 in you router. See the technical application note on how to configure your router.

TargetTrack Site Data Entry


After you have installed SignalTrack, launch the software. When the wizard appears, select Blank Fixed Site Mission. On the maps wizard page, push the Load Maps button and select the “Area Around Phoenix” map that you downloaded. Press Next.  In the next dialog, enter a frequency of 162.55 and name it “Phoenix WX”.  This is the local NOAA weather frequency.  Press Finish and save the mission.  Next, you will enter the site. Press the New button and fill in the information as shown in the figure below. Press Done and you should see the site centered on Carefree, Arizona. Next, tune the receiver to 162.55 and press the Run button (lightning bolt).  The site should be showing bearings emanating slightly south of Phoenix (near the G in Guadalupe).

Signal Track Fixed Site Data Entry

Occasionally this site is down for maintenance and new equipment installation. If you have trouble getting a connection, please contact us, and we will let you know when the site will be available.

SignalTrack Playback Demonstration

The installation disk that came with your RDF includes the data required for the playback demonstration. You can also download the software demonstration.  The data consists of two playback files and two maps.  Test case 1 contains data recorded by a single mobile site trying to locate a transmitter.  Test case 2 is a mobile site using data from a fixed site to find the transmitter.

First, to run the demonstrations, download and unzip the demonstration files and save them on your hard drive. If you haven’t installed SignalTrack, download and install it.  Launch SignalTrack, and when the wizard starts press the Cancel button.  Go to the Maps menu and select Map Menu Builder to display the dialog shown below. Press the Add button and select Maps.  Navigate to the directory where you saved the maps and select both maps. 

Map Builder

Next, select the “Carefree 2” map from the Maps menu.  In the File Menu select Playback.  Finally, navigate to the directory where you saved the playback files and select the file you would like to view.  After selecting this file, a dialog box like the one shown below will be displayed.

Playback Demo

Use the controls in the playback to start and stop the playback or to fast forward it as you would in any playback.  All the controls within SignalTrack function as if a radio direction finder were connected to it.  Use the Insert and Delete keys to capture mobile bearings.
