If you want a "TR-alike" contest program you might want to give TLF 
(http://home.iae.nl/users/reinc/TLF-0.2.html) a try.
Console application, but runs in X-window; makes use of hamlib 
(http://hamlib.sourceforge.net/) for radio- and rotorcontrol and cwdaemon 
(http://www.qsl.net/pg4i/linux/cwdaemon.html) for cw-keying.

I have it installed on my laptop but did not do a life contest with it. 
(Antenna is still on the ground).
