Composite Signal from Spectrum 48k

Hi,

Just a quick question for you all.

I have a nice new LCD Monitor which has Scart. composite and S-Video inputs on it and I'm using some of my older machines with it (Acorn Electron/Atari 800XL and VIC 20)

However, what I want is to be able to use Spectrum 48k's on it via a composite signal. I know you can modify the 48k and get a composite signal from the RF modulator but I don't want to have to modify all my 48k/ 48k+'s this way.

I know you can get a composite signal from the edge connector and I have modified a RAM Turbo interface to include a composite video connection.

However, the picture is not stable and rolls. Is this due to the fact that the signal from the edge connector isn't 75 ohms, how can I get round this ?

Thanks in advance.
