TR4W (TR for Windows) is a freeware program for operating in amateur radio contests. Program is based on source code of the TR LOG MS-DOS program, kindly provided by Larry Tyree, N6TR (author of TR LOG). The basic idea of the TR4W project is porting TR LOG code to the Windows environment. TR4W is written in pure Windows API (application programming interface) and designed to be as small and fast as possible. Size of the executable file is only 160 kB. At the same time, the program contains almost 40 windows and consists of more than 100,000 lines of code. The TR4W project was started in March 2006, by Dmitriy Gulyaev, UA4WLI.
