Improving P21 colors


When playing around with P21 (Dr. Ting's kit) I am having
real problems with some of the colors on NTSC.
Jeff Fox told me that some people have tried to improve them
by applying a filter (capacitor) to the output signal. Also
the XTAL's closeness to the NTSC pin may introduce noise.
Can anyone who has tried any improvement relate his experien-
ces here (positive or negative) ?
Thanks,
Klaus Blass
