That's a circuit board I laid out. You can see my signature at the bottom right of the board, next to the 10-pin IDC connector. 30 copies of it were used in the Arecibo Search for Early Hydrogen for a few years in the late 90s. I didn't stay in radio astronomy long after that, but I'm still saddened by the news yesterday that they're going to have to take it down.
