Long-Lost U.S. Military Satellite Found By Amateur Radio Operator:
There are more than 2,000 active satellites orbiting Earth. At the end of their useful lives, many will simply burn up as they reenter the atmosphere. But some will continue circling as "zombie" satellites — neither alive nor quite dead.
"Most zombie satellites are satellites that are no longer under human control, or have failed to some degree," says Scott Tilley.
Tilley, an amateur radio operator living in Canada, has a passion for hunting them down.
In 2018, he found a signal from a NASA probe called IMAGE that the space agency had lost track of in 2005. With Tilley's help, NASA was able to reestablish contact. But he has tracked down zombies even older than IMAGE.
"The oldest one I've seen is Transit 5B-5. And it launched in 1965," he says, referring to a nuclear-powered U.S. Navy navigation satellite that still circles the Earth in a polar orbit, long forgotten by all but a few amateurs interested in hearing it "sing" as it passes overhead.

You are right, this is a cool story. It is the kind of thing that brought me into the amateur radio hobby. Actually, wanting to build my own radio telescope was a big driver.
My Google-fu is failing me, but there is (was?) a guy down in (I think) Texas who has a huge antenna, many meters long. And the way he points it is that one end is at a fixed point on a rotor, and the other end was supported in the bed of a pickup truck. To point the antenna he would drive the pickup around in a circle. NASA had come to him to find spacecraft that they lost contact with. I remember seeing a picture of his setup, which was pretty cool, but I'm having trouble finding it on the 'net at the moment.
I'm reasonably sure this was down in Texas because I think he had some connection to NASA Houston, like being a retired engineer or something.

Google W5UN antenna. I think this is what you are looking for,
