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.
