[QuadList] Servo Modes

I agree with you regarding the state of many machines in TV stations.  I went to one and all four heads in the ACRs were down below a half mil.  No one could figure out why the dropouts were so bad.  

VR 1200 Lock up times were terrible.  After a few hours on each machine they looked a lot better.  Still could not break the habit of some operators of using H lock mode.

I also found that a number of folks had no idea about standards and operations to make them look good.  It was throw a tape on and it was good enough.

If you are concerned about the horizontal position, then the 4/8 field lock should be used to sort of color frame the output.  Lock up time is not important for making dubs and digital capture.  When I first worked at a station, we ran all machines in H lock, so a station break consisted of 2-3 spots rolling from net to spot to spot to spot to slide to net.  My guess some people at home never saw a locked picture on their slow sets until we went back to the net.  So a couple of us worked hard to get all machines to auto lock and our breaks were vastly improved.  It was interesting to think many of these machines actually got better than when they were initially purchased due to the modifications and service by the local techs.
