Hi, Frank,
Attached to this post are the details of the Revision C version of the Main Board. The principle change is the incorporation of the Spur Elimination module rather than having it as a separate attachment as it is in the Revision B version. On the image, you can see this in the top left-hand corner where there are two transistors marked Q1 and Q2.
Also attached is the schematic for this board.
Hope this helps.
73, Adrian, 5B4AIY
