Thanks. I guess I thought there was an extra degree of freedom so you could pick the turn over temperature. The graph at the bottom of this URL http://www.4timing.com/techcrystal.htm shows that there are actually 3 turn over temperatures. Do AT crystals used in ovens take advantage of the UTP? ---------- So we are just lucky that an AT cut works well at a convenient temperature and that an SC cut works well with an oven. A life form on some other star might not be so lucky. -- These are my opinions.
