The Culprit

See the differences between soldered and unsoldered pins.  How did I ever miss this the first time?  This has been the source of all my woes the last two days.  Jim Garland and Dave Trainor have been trying to help me troubleshoot why my RF Path does not seem to work.  We found that the relays were not switching globally either in the RF switch box or the master controller.  The set of pins in the center are from U-204.  The pins from U-203 below it are shiny and well soldered.

Merry Christmas everyone reading my blog.
