In Canada and the U.S., a good source for small quantities of PCB's is EPCircuits (ph: 604-824-1238), (www.uniserve.com/epcircuits/) in British Columbia. Good prices and very good service. Ask for Gary Kwan. I signed on with Prodigy to access the newsgroups (electronics, am.radio, etc) because my employer's system doesn't provide it. THAT is wasted time and bandwith... along with about $38+ per month of my cash. This list is very informative: PIC's, and all the RF, IR... we all have to do that periperal work that goes with each project. Thanks, pull ahead... John "I ain't stickin' anything in a cow" Leonard
