The wires are 18 gauge unshielded cables, up to 60 feet long, running through the house. They all pass near the electrostatic filter, which is basically a small lightning generator. The current board will glitch the furnace relays and LCDs when the electrostatic filter sparks. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
