Here it's now primarily about the basics of the standard and the basics of what others have done in regards of the original 120/128-line monochrome SSTV system. If you wish to add details of what you have done, what you built and what its status is today, I suggest kicking off a new thread as I will do for the SSTV-625 up-converter.

i also have stuff scattered on the forum i would not mind placing here instead of in the off Topic area .

Just PM me or a moderator and we should be able to move things.
For moderators' reference, at bottom-right of any topic thread there is a "Quick-mod tools" menu. From that menu you can select "move posts" and then GO
That takes you to a selection page where you select posts and their new destination

By "here" I have assumed you meant to the SSTV forum, and so it is done.
Easy to move anywhere, so let me know if it's OK or not.
Steve Anderson wrote:Well, the board layout implications of the posting above are more than I expected! In a positive manner. I may shuffle things around to reduce stray capacitance. The differences between the MkI version and this MkII version are plain to see. MkI on the left, MkII on the right.
But before I get carried away I MUST work on the timings - something for the weekend.
Now the question is where do I place this thread? It's both NBTV and SSTV.

Sorry, pdf for reasons mentioned above. I'm waiting for my Acad expert to return from Malaysia, late this evening I think.

I went by car/ferry at friday, stayed at the friendly home of Chris and Pam Lewis in Loughborough, visited the Convention in Eastwood at Saturday and drove home during the night, from 17.00 to 03.00..... pffft.
I had taken my Heathkit like SSTV monitor to show, while Chis showed his little B&W Arduino based SSTV camera and his Raspberry Pie display. We tried to connect both setups, but that failed because of incompatibility of cables, plugs and systems. The things Chris made work only after a VIS code and the camera sends only one frame and then stops. Then it has to be reset and after some 10 seconds a new frame started sending.
Chris gave me two older books on SSTV, one of them written by Grant Dixon, the man that involved me in the club. Then I found out how chaotic SSTV became and why I left it just in time. It became obvious for me that different individuals and companies developed a multitude of incompatible systems and modes, such that all users had to buy all their new "products". During that process the system moved steady away from the area of television, into the direction of facsimile, where it takes many minutes to send one photo. Sending a .jpg would have been a much better idea. Yes, now.
It looks to be a good idea of you, Steve, to keep away from this chaotic mess and return to the source, where it is difficult enough to come to a good working system. So, lets work into that direction.
