For you other FACNET members Rustic Alpha was not a personal call sign like most of the other phoenetic Rustics but the call sign of the Rustic radio relay station located on Nui Ba Den, RVN. I am not sure when the transaction took place but it later became known as Sundog Alpha, most likely some time in 1972 . Rustic control was the call sign of Rustic op's both at Bien Hoa and at Ubon.
