Build a 10 GHz upconverter from a downconverter by PA4DAN LNB's without a build-in feedhorn are generally the oldest and easiest to rebuild. These old LNB's are only capable of receiving the lower band. The local oscilator works on 9.75 GHz. If you change the LO frequency to 9 GHz, the entire 3cm band will range from 1000 to 1500 MHz. http://pa4dan.nl/ham/homebrew/upconverter/
