Sorry, "S-33963" (if that's your real number...) but it looks like there is lots of interest in using RF modules in conjunction with PIC's. Glad to see so many people here that can provide the facts. The RF mod I've been playing with from Abacom Tech. of Canada is indeed manufactured in the UK. My next stop is FR Monolithics. "PIC'n Up the Pace" and "Easy PIC'n" are available from Jameco Electronics (www.jameco.com), but Myke's book isn't. Where can we get it Myke? I have had similar luck with the magazine projects. I usually wait a couple months to read all the letters-to-the-editor with the needed corrections.
