Russ,

Actually that disassociation is what i am counting on. In my TC there are
two ground systems RF and Equipment. The RF ground is out at the coil some
30ft away and is for the most part unrelated to the Equipment grounds back
at the console. I feel this helps keep the wild stuff off of my control
equipment and adds an extra measure of protection for the operator. (that
guy gets nervous some times)
