A chat with Gary i now understand whats happening with 400hz FSC 3 colour frames one after the other at that line rate so a bit of flicker on that one .
All the FSC systems on Video2NBTV being all experimental and for Gary more a personal experiment we have to be grateful to Gary letting us experiment with them in the first place.
A 1.2 khz system version as been made for me so i don't have to change any thing constructed really so big thanks to Gary for the help here .
So with that cleared up i have nothing really at the moment to view the 1.2khz line rate 12,5 hz frame rate FSC on .
PC wise so far apart from off line rate on B/w software seems to give best results on 48 line on Doms viewer as in i can see the the red blue and green frames one after the other i suppose .
I have been working on the the sync part of it bit more now circuit below using a Lm567 tone decoder, the Klaas and Steve's reworking of the sync slice circuit works fine as it is for 400 hz and seems to up to 3.6khz but to clean it up and use the higher line rate pulse i am using a 567 a reworking of this circuit for only 400hz .
The results seem fine ,but i do have to switch the capacitors on the 567 to change the working frequency range as expected .
I did run both circuits on 5 volts so far not 12 5 as shown so need to test that next my mistake on the circuit
