I modified the UHFSDR design to replace the GTL2002 with opto isolators. That change is on page 4 at <http://wb6dhw.com/UHF-SDR/UHF_SDR-sch.pdf> I still have to make the change to the PCB. One other item I am looking at is the best way to provide for substituting another external oscillator for the Si570. The differential outputs of the Si570 make it more complicated than just not installing the Si570 and running coax to its output line. Dave - WB6DHW <http://wb6dhw.com>
