Started to investigate integrating the DRiACS dish controller into my existing system, beginning with an eddy current damped gravity pendalum elevation indicator.
I was extremely disappointed with the Machine-DRO digital pendalum inclinometer. Although the reading updates very quickly ( too quickly?) it is very unstable. It seems to be similar to the well-know 'Lidl' digital inclinometer. That is also totally unsuited to moon tracking as it takes ages to settle down to a reading. The Machine-DRO is exactly the same. It is suitable for indicating elevation if hou have time (>30-45seconds) but totally unsuited to tracking, where the 'noise' masks the immediate moon (or sun) position.
So, i'm back to trying to implement the MAB25 absolute encoder solution, but with the possibility of using eddy current damping to reduce reading instability, especially during windy conditions when the dish mount will inevitably shake.
On a very positive note, the add-on GPS clock works well, even inside my garage shack. GPS lock is solid. The DRIACS indicates the actual moon ( or other celectrial object in the almanack) without worrying about clock drift.
