Yes,

I've recorded some of the Aerotoon's onto video using the
A520 on my 500. The 520 outputs composite video (colour).

    I have also used the CBM A520 video modulator. It plugs into the video
    port on any Amiga and output color composite video or RF modulated
    video. The unit cost about $30.

    Yup, the A520 works fine on my A3000, also.
    
    You should get some of the intro-to-Video books and look through those,
    though.  The rules about colors, etc are even more important than if
    you've got a genlock.

	Yeah, my performance tonight at the Perforamnce Place in Somerville
	uses  a video tape of Amiga graphics.  I used  a Creative Microsystems
	unit with composite out (also chroma and luma).  
	There is a behaviour with it that I bet is common to all of them.
	It behaves as though it has an automatic gain control on each
	color, but by monitoring the overall gain of all colors (or luma).
	I had these dark blue screens , and they went green.
	Well, it was as though it said, "this is too dark, let's turn up
	the red and the green".  Red and green make yellow, and yellow and
	blue make green, so I got green until I turned up the blue to 
	very bright blue.  Still pure blue though.
	I think this might be required by video standards; something 
	about average brightness.
	Don't buy something for $25, they stink.  I have one you can buy
	for cheap to experiemnt with.  The CMI one is about $60, or was.

    I've tried recording taking the signal straight from my modulator into
    my video,but the video doesn't seem to tune in to this.All I get is
    interference as if the video isnt in sinc with the signal from the
    modulator.As I am in the UK could this problem be due to the different
    television system over here? Or has anybody in the UK managed to tape
    from their modulator.

A modulated output should not be connected to a video input.
It is modulated to be connected to an antenna.  It should be connected
to an antenna, say a 75 ohm antenna, or a transformer from 75 to 300
if you have 300-ohm antenna terminals on the VCR.
An encoded output should be connected to a video input.
The encoded output is labelled composite.

I think that when .5 says ; 

�I've tried recording taking the signal straight from my modulator into my video

what he perhaps means is "into the RF input of his VIDEO cassette recorder"

"video" is an affectionate little term used in the UK which means the same
as VCR in US-speak or "magneto..." in French-speak

Normally this is OK, the problem could of course be encoding and modulation
compatibility when using RF systems from different countries.  I understood
from .5 that the author thought the "television system was different over here"

Different from where?  If you bought your Ami in the US and it has an
RF output, then surely it is NTSC format?  If the VCR you are using actually
works in the UK, then it sure as hell ain't NTSC compatible (unless being
a mug like me you forked out over �600 for a multi-standard).

My Ami 500 (actually a CDTV) bought in the UK, came with a special modulator
fixing plate labelled "RF - PAL"  I presume they swap in appropriate modulators 
depending on country of sale.  

If you have an American device its RF output is irretrievably useless for 
recording on a mono-standard UK PAL recorder...

    
    Peeds,
    
    	Assuming you have your connections right i.e. Ami modulator output
    to VCR aerial input have you tuned in your VCR input channel to the Ami
    output frequency. I believe the Ami output is approximtely Ch. 36.
    
    	Ch. 36 is also typically used as the output channel of the VCR so
    you may get 'bleed thro' if so you could try adjusting the output 
    channel of either the VCR or the Ami.

    I got it to record by taking the signal from the video out to video in
    on the VCR,rather than trying to tune the VCR to the output of the
    modulated signal.Thanks everyone for their help.
