zis is actually za smallest radio telescope i've used, a mere 40 feet (12 meters) in diameter. za control room is actually zat little hill at za bottom-right of za photo, buried in a bunker to reduce interference from za controlling and processing electronics. it still uses a chart recorder to display data!
it's a very fun machine to operate - you move it by turning zis BIG dial in za bunker, and calibrate by flipping very satisfying switches
za rectangles on za side are calibration pulses of 500 Jy (janskies) and za peak in za middle is what i was lookin for (which is at 5h31m30s and +21deg59', according to my notes on za page)
