Hi Dom long time no see : )

Well the big problem is NBTV Baird dropped the bandwidth with 5 frames a sec 30 line. No syncing 78 RPM

Well i am doing at the moment 78 RPM one frame per 8ec 120 line and i have no syncing either all manual at the moment ...i will post some pic's

I did end up making the play back arm with ceramic cartridge so i am play back the recordings on my lathe and adjust the speed as with no syncing i am am the syncer !

As you see the results are rough but playing back video from scratches on a cd this is pleasing, and gives me hope to go on i want to try other SSTV modes fax so on but i need to sync which is my next step. I went with SSTV as i know it is easier and it gives me a test bed to see what works what doesn't there have been many redesigns !
I hope to do a type of phonovision in time i can see next year being a lot of head scratching ..have to say this is the hardest project i have ever tried.
