When I originally replied to Hector's comments about the RIT problem, I
copied Paul Clinton on the reply.  I received a reply from Paul and want to
pass it along showing how much effort Paul and Ten-Tec have put into the
problem.  If you have a problem, please call and try what he suggests.
Maybe we can get to the bottom of the problem and everyone will be happy.

Dear John:


Thanks for the update. The RIT failure is one of those unsolved mysteries.In
some rare cases the RIT encoder is defective and replacement will solve the
problem. In the cases where the encoder is defective, there is no problem
reproducing the failure on the service bench. One customer with the
intermittent failure insisted that we change the encoder, the encoder was
changed but the failure returned after a few weeks of operation. In other
rare cased we have found a broken solder joint where the encoder is attached
to the circuit board, again no problem getting the RIT to fail on the
service bench. I have literally spent days using an Orion with the
intermittent RIT failure and have been unable to reproduced that failure.
The Orion was operated hot and cold. The Orion was controlled from a
computer using various logging programs. I spent hours with the Orion
engaging the RIT, raise the frequency using the RIT, reset the RIT, decrease
the frequency using the RIT, reset the RIT and it never failed. Engineering
spent a week with the same Orion and could never reproduce the RIT failure.
If the RIT failure is a software glitch,  we are unable to reproduce the
series of button pushes that trigger the failure. If the RIT failure is a
hardware problem, it is logical that it would surface on the service bench
or in our own shacks. We wish to solve the mystery of the RIT failure as
much as any Orion owner but unless we can reproduce the RIT failure, we can
not discover the cause. I would encourage any Orion owner that has the
problem to call me when the RIT on their Orion is in the failed state. If I
could talk to an owner who is in front of an Orion in the failed state then
perhaps I could discover the source of the problem.
