OSCAR 7 is Alive

AB3A writes :"Originally launched November 15, 1974, OSCAR 7 was long thought to be dead from natural causes (radiation, battery failure, space junk, etc.). However, AMSAT reports that it has recently been heard on the air! This probably isn't a record, but it does rank right up there with spacecraft such as Pioneer. I wonder how many other satellites out there have been given up for dead but are still functional at some reduced capacity?"
