I'd think many may not want to honestly participate in this discussion simply to avoid bringing up former quilty pleasures like ?????????????????, ###########, !!!!!!!!!!!!!!!!!!!!!!! and ************* which is where many of us I suspect learned to aim a Ku dish. My linear experience started with looking for 79W as my due south but somehow finding 97W by totally random chance after hours and hours of frustration (and then promptly losing it when I moved the dish again!). Then it was finally 72W after another extended voyage of discovery with my roof top dish (which i did manage to lock down).
