Demonstrations
Our SignalTrack software provides a tool for controlling and viewing data collected by a network of direction finding network. You can evaluate our software by downloading it and running it in the playback mode or if you would like you can connect live to our two VHF direction finding sites in the Phoenix area
Play Back Demonstration
The data required for the play back demonstration is included on the installation disk that came with your direction finder or it can be downloaded. The data consists of two playback files and two maps. Test case 1 is data recorded by a single mobile site trying to find a transmitter. Test case 2 is a mobile site using data from a fixed site to find the transmitter.
To run the demonstrations download and unzip the demonstration files and save them to a known location 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.
Next select the Carefree 2 map from the Maps menu. In the File Menu select Playback. 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.
Use the controls in the playback to start and stop the playback or to fast forward it as you would in any playback of data. All the controls within SignalTrack function as they would if a direction finder were connected to it. Use the Insert and Delete keys to capture mobile bearings.
Live Data Demonstration
Doppler Systems maintains a VHF direction finder site in the Phoenix area that is connected to the Internet. The site is used for equipment and software test but is normally available and can be used by our customers. If you would like to use this site, download and install SignalTrack and download a map for the Phoenix area (press here to download). Launch SignalTrack and 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 and 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 then save the mission. Next you will enter the site. Press the New button and then 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). Bearings should be shown emanating from both sites and intersecting slightly south of Phoenix (near the G in Guadalupe).
Occasionally this site is down for maintenance and new equipment installation. If you have trouble getting a connection please e-mail us and we will let you know when the site will be available.
