Hi Jim. I think I must have a configuration problem with my computer (it is used, but new to me). I can see the box for the attachment but there is nothing to "click" on. I would like to see your schematic. It sounds like just the thing. I am sure that someone on the list can help. Thanks for posting the circuit. 73 de John
