Last weekend i tried to put my new 23cm transverter with 28MHz IF and the 100W PE1RKI PA together. The picture shows my ugly “transverter in a box” construction.

I used this setup in the March 23cm DUR contest. My ODX was HA5YA via aircraft scatter about 550km distance. I also worked DL3IAE and OM5CM, both >400km.
