Glenn VK3PE has built up one of the 9 component anti thump circuits described by ND6T (but it is in fact a design by VA7AT ).  He has yet to actually try it in his rig.

The PCB is about 26 x 10mm in size. Only difference to ND6T’s version is he placed the 10uF’s on the PCB also. ie remove from uBITX board and fit to this board. Otherwise it follows ND6T’s web page for installation. It is made from SMD 0805 parts.
