There is no web site that I know of for it. However, there is a brief piece on
it on the Handi-Ham web site. The e-mail for the guy who makes them is
[log in to unmask] and his name is Remy. He's great about answering
questions. If you can't get the info you need, drop me an e-mail and I'll
forward you the brief sheet that comes with the equipment and a couple e-mails I
got from Remy with information not in the instructions.
