 TS-440s update

  If you have been having some signal loss on either receive or transmit,  you
might check the J-15 connector on the IF board(X60-1300-00).  I am not quite
sure just what this circuit is doing (feedback or signal),  but have been
having some troubles with loss of full signal output,  and a noticable 20+db
signal loss on receive.  Generally a quick slapp of the case restored the unit
to normal (I thought) use,  but within a few day's it was back to having
trouble.  Well it only took me 3 months to decide to find the culprit(s),  and
decided it had to be either a bad connection,  or RING-OUT.  After taking the
case apart as was actually going to replace a bulb,  I noticed that the signal
strength was going up and down as I worked on the rig (never work on a rig with
power on,  unless doing alignments,  or testing,  never to replace a bulb!
hihi)  Anyway I got to moving some cables around and noticed that under
certain circumstances that the signal would go from very weak to very strong.
