LOL...You are starting to go over my head a little bit..(just a little) Thanks for the information though, and BTW, it is H-E-A-T-H tech, not healthtech (honest mistake guys) ...LOL just like the old Heathkit radios, coincidence? Nah, my mother named me after an old American TV western show called "the Big Valley" with Lee Majors, who played Heath Barkley on the show. Maybe it was destiny that my second love (always second to my family) is electronics. LOL...BTW, Healthtech is not an approriate description of me, I weigh 225 lbs...not sure what in Kg,s...LOL
