I've been following this sort of off and on, so forgive me if this has already been mentioned. DJ, your LCD has a back light, doesn't it? I've seen touch-sensitive screens using flourescent back lights which are powered by several kV generated by an on-board switcher. I'd imagine the LCD display also has a switcher on it to generate the backlight, and if the display is an el-cheapo model, well, the switcher could have all kinds of noise-prone components on it. Just a thought. Stuart _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
