Look for a copy of my presentation some years ago held during EME
conference in Dallas, shows a mechanical solution. Have used it for many
years on all our DXpeditions. Think it is still available somewhere in the

Hi all,

Look at the controller on web pages following .
This will use
1.)  pots,
2.)  z-index incremental encoders
3.)  absolute



pulse encoder "MUST" be quadrature data or will not count correctly. The
system is 100% error free, also capable of .001 degree accurate or better

This is partial explain how this system

z-index incremental encoders  quadrature data (100% error free)


hope this will enlighten those of on going error problem of "simple pulse
that type can not be fixed for the count error.

W2DRZ  Tom
