Interesting project. One thing seems a little odd. You use an attenuator to 
reduce the level of the 28MHz signal as it would be too much for the 
transverter to handle. You then say you then need to amplify the transverter 
output because it only puts out 1mW but you wanted 100mW.

It makes me think you could simplify things if you used a different 
transverter that would give you the higher output since you are only talking 
100mW. It could let you eliminate the 28MHz attenuator, the 1mW to 100mw amp 
after the transverter, or possibly both.
