Hey all,

This might be a silly question? But please no silly answer! :D

If I wanted to source the best composite signal from the Falcon motherboard, where would I take it from. (Please I don't mean from the output connector, I mean specifically on the motherboard, the best source component)

Cheers

Not even sure falcon has C-video.. possible as its driven from the MC1377... but its only called C-SYNC on there.. Even so, should really just use the video connector...

So it looks like R31 would be the best place to solder a wire?

By the way, as far as I know the RF modulator takes a composite signal from MC1377 to create the RF. C-Sync should not only be carrying a sync signal, but also the composite image.

You would have to scope the signal, and on the monitor port.. the port should have a filter on it, so "soldering direct" could actually be worse.. If you want better video.. why not just use RGB.. composite is almost as bad as RF!

I don't want to use composite as my main signal source. I just want it as a secondary output. I ripped out my modulator internals and fitted a standard composite jack. I guess I'll try wiring it to the output jack again, it's just I did try before without any luck. I might have done it wrong though, so I'll just have another go.

I'd probably go for either leg of L28 depending on whether you want to be upstream or downstream of the ferrite bead.
