[TenTec] RIT/XIT Problem back

It can't be the cable.  If you look at the menu, you can change what the
frequency on the remote pod, RIT/XIT and PBT/BW.  I have never had it fail
using the remote pod.  The wire in the ribbon cable is the same pair that
controls all three functions.  It is a software switch that controls where
the signal goes.  Since that works fine, I know it must be somewhere on the
encoder board which is behind the front panel.  By mounting it is standoffs,
I can touch things in the RIT/XIT circuit flow and hopefully find it.

John: I started seeing the same problem for the first time a few weeks ago, 
and I performed the fix you described back in July on connector J8.  That 
solved the problem for me, but it's always a possibility that simply 
disassembling the case is actually repairing another lose wire or circuit 
board trace somewhere else.

The interesting clue is that the RIT/XIT control is the one that seems to 
have the most problems even though it's generally used less than the Multi 
or Main AF encoders by most ops.  I'm still suspicious of the cable.  Those 
ribbon connectors with the "wire stabs" that punch through the insulation 
have failed on me in other types of equipment.  Perhaps swapping the two 
cables might cure the problem, or make it manifest itself in a different
