YES, the TS-2000 will work linear transponders. You need to put the radio into "Satellite mode" and it will do any mode in both the main and sub bands.
The difference between satellite mode and just using the "sub receiver" is that in satellite mode, the main side of the radio is receive only, and the sub is the transmitter only (no receiver function).
So, check out the purple satellite mode button :)
