Hi Gary i didn't see this message when i i was testing earlier on adjusting the sync i had it on full before adjusted it here in the wav file video ...but yes i see the wavy look when playing back ..i can disconnect it now i didn't know till i had this problem with the sync mixer transistor that your software would still play just the video signal on its own.
Sort of hard to keep focused on one problem at a time as i have a few i need to fix and i do jump about .
In relation to that, however, one thing we didn't discuss (I don't think) is whether your disk is running perfectly concentrically - that is, is the side of the disk, taken at any position, always in the same position when you turn the disk? Or does it move back and forth, or up and down?
It pretty much has to run true as we are talking a mm or less as it rotates in its case so i would think it is ...but ....i used a template placed over the disk to drill hole positions so it is more than possible for this to be i a touch off so wobble could be this a touch off perhaps ...
Placing some reference near the edge would give you a good indication of that.
Its the reason i like to use a dvd or cd as i reused the mounting connection left on the motor so the disk it pretty much spot on as it would have to have been when used in a cd or dvd player .
In fact, it is more important (to what I am thinking) that the edge of the ENCODER is concentric to the disk, AND that the disk runs true.

Well yes here to on the encoder centering in place.... i do this by eye and i know i could be a touch off here too and this would also cause a wobble in the sync as the encoder does taper down in size.
I will try and do a sync less test ....
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
