If you like to build a transverter, Paul, W1GHZ, has designed a bunch of
CHEAP to build units and has poted the information on his web pages at

Here's the direct link to the Multi band Microwave Transverter project
that he gave a talk at Microwave Update about this past year:

I am currently building the 900Mhz version and still have to acquire the
MMICs for it as I have found that I have misplaced the bag that I had
from years ago.

BTW, I do have a extra DEMI board model number 1296-144 that I would be
willing to part with if your interested. Just the PCB board. The cost of
acquiring parts on my own cost me about 75 dollars ten years ago though
and I don't know how 'unobtainiam' some of the parts used are now a days
though. It could be used for 1260 Sat or 1296 Terrestrial depending on
what crystal was installed.
