Wow! Thanks Bill, if possible, as long as you are going to the meeting
tomorrow (it is tomorrow, right?!?)? I'm 90% sure I'll be there so, just
bring it with and I'll take it then. I'm sure glad that I'm getting the
help I was looking for. Curt and Jeff have been very helpful with this so
far and my hat's off to them!

Anthony:
Curt is giving you some very good advice....I have a SWR bridge that you
can have..glad to help.
You can give me a call and we can make arrangements for you to get it.
Welcome to the hobby..
