Having found it necessary to replace one of my encoders, I took it on myself
to see exactly why the other one failed. There is a rubber or synthetic
material ring inside that is used to provide damping and provide a seal to
the shaft from the outside world. I found this ring had basically "balled
up" or galled in its race around the shaft causing the shaft to bind. Then
the mis-alignment of the shaft caused the wiper on the segmented control to
also become mis-aligned.
To me this is a quality issue with the manufacture of the control and is one
not likely to show up until some time later. Thus just as reported.
Now with all that said, the new encoder has been in the radio for some time
and still shows a nice degree of dampening on rotation but no other issues.

This happened to mine too, after just a few hours of gentle use. The
multi-knob froze up.
TenTec arranged to have UPS pick it up to ship back to them. Apart
from the shipping time both ways, they turned it round in one day.
When I received the Omni VII back, the note inside said that 3
encoders had been replaced. Everything feels smooth now, as it should.
Although this shouldn't have happened on a new rig, TenTec could not
have done more to rectify the problem so quickly and efficiently.
