Lee have you seen the nice article on manhattan lowfer tx at 
http://members.shaw.ca/ve7sl/lowfer.html

Might be good reference to what you are doing. 

Say HI to Bill I have tried to get him on here but he is reluctant to 
join. I had hoped he would see reports on WEB. He is one of my favorite 
people.
