News and Updates Radar Trainer 3 is a new program and we expect to periodically have updates to the various components of the product. These include the two main simulator programs RT3 and RT2a, documentation, tutorials, and simulation examples. Click the topic name to download. Install instructions are included. These updates will not open or function unless the full Radar Trainer 3 program has been previously installed and registered. A new KEY is not required, but you will need your serial number for the installer. Download to some temporary folder, then double click the file name to execute the update installer. If you have changed the default folders we recommended on original installation, you will need to make this adjustment when asked in the installation of these updates.  If during the update process you are asked to write over "read only" files, answer yes.
