Wiring : Keep all wires as short as possible, this is an RF measurement tool after all . Many builders will also connect Filters to the power input, in order to remove even more outside interference. If you have a second AD8307 board, connect it to IN-B, this will add the SWR functionality. Search the web for SWR bridge project . The enclosure part is interesting project by itself , I build mine by using double sided PCB's. I cut all four sides , cut the LCD window , drill the buttons and BNC holes, solder all corners together , spray paint with black paint ,and then assemble all the the rest inside.
