Thanks for everyone's advice. Sorry about title SQR versus SWR which stands for Structured Query Language from Peoplesoft which I use alot.
As it turns out my antenna is up 30 feet not 40 feet, ends at 15 feet, and this last weekend we had rain on top of snow and then ice which, of course, drove the SWR up to nearly 3.0 to 1 at the center frequencies on both 160 and 80 meters. It appears to be OK on 40 which again confirms the height as being the possible problem. Much of the rain and snow has partially washed away and dried up and the temperature is now close to 0 and as expected the SWR is also much improved at about 2:1. I guess I cannot complain since I was able to work several caribean DX stations on 160 meters over the weekend with the antenna and a tuner.
The antenna was built from a 1992 QST article. Here is the link to the article on ARRL web site by W8NX. http://www.arrl.org/tis/info/pdf/9207035.pdf
