probably not - but its years since I worked with Secam. The subcarrier
being FM should avoid cross-colour problems. Secam did have another problem
in that the output of the colour part was at a fixed level while link fading
could change the luminance component; the result was varying colour
saturation. Mind you a decent agc circuit should stop that.
