The uWSDR (Microwave SDR) will not need a transverter, it will provide a 
transceiever operating at the frequency of interest (144, 422, 1268, 
2400 etc).  It will cover the whole of each band - i.e. 1240-1300MHz. 
Full duplex cross-band products such as L/S are planned specifically for 
satellite use.  The hardware is still in development, but progress is 
being made, and software can be downloaded now and used either in 
simulator mode or with a Softrock.  The hardware should be available 
long in advance of the next HEO launch.

Detailed system simulations show that the RF performance will be as good 
as, and hopefully significantly better than, a transverter/IF combination.

More details on the uWSDR website - fell free to join the project if you 
so desire, any extra help would be appreciated.
