First off, let me thank you for your assistance and direction here. You 
pointed me to the sqlite utilities which is what I was wondering; can I use 
them here. I am taking the time to learn more about sqlite database.
Second off, thank you for kindly answering when I clearly didn't use the 
group search function effectively. There is a lot of useful information on 
this group. 
Thanks for sharing the nice weewx application too.

Brian
