After debugging many issues one step at a time, Ant 26 has signal all 
the way through the system on IFs A & C at X-band.  Jerry is going out 
tomorrow morning to wrap things up in the vertex room so the antenna can 
be pointed.

Ken helped confirm a bad L302 in antenna 24 today.  All fibers, cables, 
etc. checked good, so I swapped the L302-1 and the L302-2.  Ken then 
reported that the problems seen at all bands on IFs A & C had now moved 
to IFs B & D.  I removed the faulty L302 and left IFs A & C working in 
ant 24.
