Hello This evening (0325Z) on AO-51 my old S band AO-40 (sobsob) still works!! No one else was on, only the west coast was available. The biggest challange is tracking the fast moving AO-51 with a 3 foot primestar dish with out auto tracking (next project). think HEO 2009 73 Bob W7LRD -- "if this were easy, everyone would be doing it"
