LES-1 satellite heard again

| March 8, 2013

Phil Williams, G3YPQ, an amateur radio astronomer in North Cornwall reports picking up a signal from the LES 1 satellite, a satellite launched in 1965. The satellite failed to reach its intended orbit owing to a wiring error and has been drifting out of control ever since. G3YPQ ran across it while monitoring near 237MHz when he noticed a signal with a peculiar signal drift caused by the bird tumbling end over end every 4 seconds as the solar panels became shadowed by the satellites engine. He said that gives the signal a particularly ghostly sound as the voltage from the solar panels fluctuates.
