Hey guys... I'm usually against placing off topic questions on a PIC mailing list, but I really don't know where else to turn... I hope someone can help. Where can I learn (either a text, or good website) about producing my own radio frequency communication? I am very much into amatur robotics, and I want some remote control that does not require such a short distance (like IR) and direct line of sight (also like IR). Where can I learn (from the beggining) the basics on up to the complicated about RF circutry? Thanks. -Ben ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
